THERMAL efficiency. Modern engines need to meet modern pollution targets, and thermal efficiency allows this more easily for most manufacturers. Also gives more consistent, reliable performance and longevity. 2019 I road into Berlin, Vienna, Prague, Bratislava in the summer heatwave. No problems overheating, not even burn any oil on Tenere. Liquid cooling works. Happy travels

[@motorcycleadventures]

Absolutely!

[@IngOehman]

Sure. But air-cooling works too. 😮😉 Don’t forget the history! Many world-traveller motorcyclists have been around the world. Some of then when basically all motorcycles were air cooled! Ted Simon on his Triumph Tiger (old tiger, not the moderns ones), Helge Pedersen on his BMW R80, as Sam Manicom. There has been a few old Urals, on travel and in more modern times, Ed March is using his old (1989?) Honda C90. And the Royal Enfield Himalayan that Noraly Schoenmaker is driving relys on air-cooling as well. But yes, water-cooling have some advantages. As have air-cooling.

Both Air and water cooled engines have it's own advantages and disadvantages. My personal preference is Air cooled, reason being simplicity as chances of things going wrong is less.

That is also mine stance.

[@zbynekanders8779]

AiR cooled engines are rather obsolete nowdays, they are less powerfull, usually service intervals are shorter, because oil faces higher temperatures and the problém of traffic jams has been already mentioned in video. But they still make sense in retro bikes where the power is not important and in entry level enduro bikes, which are not so expensive and not easy breakable when dropped down. Anyway interesting video.

[@motorcycleadventures]

Thanks, man!

Simple answer to your question - emission standards.

[@IngOehman]

Pavlin you are a wise old sage! Water cooled is definitely the way to go, air cooled engines run richer, making them less efficient and more polluting. Liquid cooled bikes can rev higher because they have higher tolerances due to their ability to self-cool. Air cooled can look better but water cooled is the way to go for me!

[@motorcycleadventures]

Thanks, Terrence!

[@nealeburgess6756]

I have been motorcycling for 50 years, with air cooled and water cooled. I have never once had a problem with overheating on either. My current bike (1988 BMW K75) is water cooled. In the 13 years I have owned it it has rarely even been topped up. It simply does it's job. Incidently, I live in Spain, so sometimes have done long journeys in 45 degrees heat. I did have to rebuild the water/oil pump a few years ago, but there was no drama. Just a very tiny leak. My previous bike (Honda CX 500) likewise almost never needed topping up. So for me, which cooling system is not important. Just having a well made bike, and regular oil changes (if it has a 4 stroke engine) are what is important.

[@motorcycleadventures]

Thanks for taking the time!

[@enduromotorradtouren]

As the others already wrote, Pavlin: thermal efficiency, emission and noise standards. I like the simplicity of my Beta Alp 200 engine (Suzuki air-cooled), less parts, less that can go wrong. But it's an old engine. I don't mind modern water-cooled engines, as long as they construct them troublefree for travellers. Protect water-pumps, radiators... Greetings from a cold Nürnberg, Günter

[@motorcycleadventures]

Thanks for taking the time, Günter!

[@575ban]

Engines are liquid cooled these days because it is easier to manage the engines temperature with liquid cooled engines. This makes them more reliable and easier to tune resulting in more power and efficiency. This format of you riding around your local area is very good. I can look at your home country while listening to you blether away. Let's hope the weather stays nice 🤞 Good work 👍

The best cooler system is the one you get on your bike.😝 I use my bike on different situation, in the city, on the highway, on gravel, during my hooliday . The theory is good to know but i don't think someone will choice a bike just for the cooling system. The exception is if you decide to make a bloody long distance roadtrip and you decide to choice a specific bike for that trip. This is my opinion. Good video,.thank you Pavlin.

I have never had a problem with aircooled GS 1150 and less overheating as the Transalp 700 in hot weather! Oposite to my old Yamaha XJ600 air cooled engine was very sensitive in the 35 C through the big city trafic :( Anyway, I am in love with the air /or/ air-oil cooled engines, from technical point of view it is something like art. As from old times when the engine have to a be beautiful peace of engineering. Not just stupid brick design of the fluidcooled engines. I love my Ducati twin 900 and Suzuki GSXR 1100 from 1986 as well as my GS1150, they are just a beautiful bikes. Take a look on the engine of old oilhead BMW twin, it is a masterpeace of art. Or the beautiful Yamaha XJR 1300. Compare it with water-cooled engines from Honda Hornet, Afrika Twin or well known Rotax 650? nothing to do with the beauty....

[@motorcycleadventures]

Point of view...

[@OneTwin]

Like most of the other comments I think that liquid cooled engines work hand in hand with the newer model motorcycles plus the electric fans as well in case of low speeds in the summer heat.

[@motorcycleadventures]

Exactly!

[@VLAD-fr9tf]

Greatly appreciate your Vlogging!, as for the claimed main air-cooled engine "cons" for the town which is overheating and confort: I ride a 1100cmc big twin which compared with small displacement engines with the same power+torque has a lower compression ratio and smaller rev limit (the big volume of the air intake and slow burning at low idle will cool the heads more eficiently )...of course, I must accept a double displacement and lower power than a small water-cooled "compressed" engine (but as an advantage, it will get more torque and more character than a small compressed water-cooled engine...), in the end, I found out that if the engine works properly (have the proper oil especially) it can idle in the hot summer without the slightest technical problem!, Regarding the creature comforts here I must point out that I was very happy with my V- twin compared to my fellows' sports bike guys, it needs at least 5 minutes to feel some heat when completely stopped, after that the heat will simply rise UP, the guys who have a radiator and fans must accept and even cry when the hot air will be blown toward them :) As for your question: as I see it, unlike cars, the power/weight ratio for a motorcycle simply doesn't justify a water cooling solution for average bikes, yes the performance (Hayabusa) maybe need this but not a 60-90 hp bike. As the science of metals and oils is way advanced is a pity that bikes must rely on water cooling to build cheap and stay reliable and compliant with rules. The ideal combustion engine would be the one that doesn't lose any heat and doesn't need any cooling :)...Anyway.....I assume that in 5-10 years will talk about Amps and Volts..so..no sweat for the combustion engine and life as we know now :), Good Luck and Safe Roads!

[@motorcycleadventures]

Thanks for taking the time!

[@whitedrguy6503]

Liquid cooling is good for the fact that you can run closer tolerances in the engine, mainly on the piston and rings. The big advantage being it allows a more even spread of heat around the cylinder and cylinder head, making the engine both more powerful and efficient. Air-oil cooled engines run larger clearances because you get hot spots, meaning the cylinder will not expand and contract at a constant rate. So basically water cooling is used to make engines pass emission laws, hence the adaptation of fuel injection and the death of the 2 stroke. As for which one is better ? Give me air-oil any time, after owning my DR 650 for so many years and riding in 40 degree days around the city with no issues and doing so many kilometres I love the low tech appeal. Great topic once again Pavlin. 👍👍👍👍👍👍

[@motorcycleadventures]

Thanks for taking the time again!

[@Nikki_Holland]

Good video, Pavlin. I’m jealous of your temperature. It was icy here in the Netherlands. I think most bikes now are liquid cooled so unless you are buying an old bike liquid is all you can get. I used to have a Yamaha Diversion 900 which was air cooled but managed ok during trips to Italy in the summer.

Because of the power/volume of the engine. More power from the same capacity engine makes more eternal heat. The manufactures tend to increased for marketing reasons. If you have big engine but low power it's possible even in the hot.

[@motorcycleadventures]

Than the performance will be like elefant in a muddy bath.

[@lkjagodics]

Easier to meet emission requirements with water cooling. More consistent Temps. More consistent clearances. Fuel injection or even carburation can meet requirements that air cooling could never make. I own a XR650L and would never sell it but I can tell when it is hot as it starts to get noisy, smelly (oil clearances are more when hot, oil gets past rings) and less power. That being said, an experienced rider will know when to ease off and let it cool. I still believe this is what makes it more reliable as you can tell when your bike needs a rest. Air cooling also cheaper to manufacture, cheaper to maintain and fix.

[@motorcycleadventures]

True!

[@andreykhalfin2298]

The reason is very simple: Modern technology allows to make very powerful engines. As more power, as more heat, and the air cooling system is not enough for the heat that the engines produce. The water cooling system is much more efficient.

[@mihaimihai9254]

Pravda !

[@motorcycleadventures]

[@tomdrpa7221]

Ok I understand that video is general and also focused on old air cooled bikes.... I will not hide that I own Moto Guzzi V85TT (3rd bike). This video may dissuade all potential MotoGuzzi customers. Half of opinions-facts are true, but Guzzi worked a lot on aircooled engines. They are not so powerful compare to cooled engines, but this is not a matter as power limiting V position. In case of temperature increasing ECU enriching mixture which keep heat level sustainable. Few ppl overheated V85TT on slow speeds , but KTM aside as well on some video trip. So from Guzzi side I can not agree with reliability, heating and so on. I may add following cons like changing performance and behave of the engine in cold temp - but nothing significant. Engine may drink some oil as clearances in engine are higher due higher operational temperatures. So you should be gentle mainly during 10 km after cold start. I do not know how other brands and their models, but aircoled motorcycles in 2020 does not have serious issues.

[@motorcycleadventures]

I don't want to say any bad words about your Guzzi but its performance is not even competitive with most of the water-cooled models in this segment.

I suppose it would depend on the manufacturer, but I've never heard anybody complain that they're cooling system has gone bust.

Very good video Pavlin. Interesting topic and so nice to see more of Bulgaria. A great place to visit. I always thought that air cooled engines would be best for long distance adventure trips, as there is less to go wrong. I appreciate your arguments and you make very good points. It all depends on the trip! I have to admit, i'm slightly jealous of you being able to ride around right now. Here in England the lockdown is strict and does not allow pleasure rides.

[@AceMcMoron]

Compression => power, efficiency, less emissions, but also more heat. Air/oil cooling is only for retro style bikes like the BMW R18 where only the fun factor matters. Having said that, there is something special about air cooled simple engine designs, but it comes at a "cost" in terms of power, comfort and longevity, as these engines have much more wear in the heat, but also in the cold, when the oil never reaches the optimum temperature.

[@motorcycleadventures]

Exactly!

[@Crotiger99]

Water, air and oil cooled engines are in the end air cooled engines. The difference is in what type of liquid/gas we will use to dissipate/transfer heat from the source. I have a BMW motorcycle with a boxer engine. The engine is cooled by air and oil, plus there are no problems with traffic jams because it is equipped with a thermostat and a fan. I don't see any flaws. Water cooling is "future" bc the reduction in oil capacity and emmisons standards is intended to preserve the environment. So today, highly efficient engines are made that are more enviromentaly friendly, and on the other hand, there are more complex systems that require more expensive production and maintenance, as well as a higher probability that something breaks down.

[@motorcycleadventures]

Thanks for taking the time!

[@PaulGrindean01]

These days, air cooled engine design seems to be selected for style considerations rather than objective reasons. R18 is probably one of the few new mass produced air cooled big twins we'll see. It'll be interesting to see what direction will Moto Guzzi go with their next California model.

[@motorcycleadventures]

Let's wait.

[@kevkfz5226]

Dont agree with this one, can't generalise. Very much depends on bike some a/c bikes are designed for heavy traffic in high temperatures while some l/c bikes quickly overheat. I remember taking the Guzzi into Milan once in the high 30's. The clutch was complaining a bit but it was fine. I overheat before the bike will.

[@motorcycleadventures]

You don't agree but: "The clutch was complaining a bit but it was fine". What if it was 40 or 45 degrees? With a water-cooled engine, this won't happen. End of the story!

[@prospecial]

my moto guzzi v85 is air cooled had no issues so far and the way they build the engine allows a lot of air to cool, but i have noticed that i am burning through engine oil quicker than on other machines

[@doughopkins7567]

Emissions are the main reason for few modern engines being air cooled. Tolerances can be tighter and encasing the cylinder in a water filled jacket reduces the mechanical noise of the engine which was causing concern to designers even back in the seventies.

[@motorcycleadventures]

If there were demand, there will be a supply, no matter how much it would cost!

[@gabrielwalker421]

Air cooled is easier to repair but if ur cooling system is assembled correctly and serviced on time, then the cooling system should just work without any problems or major repairs for many years. Air cooled engines run hotter than water cooled so they dont last as many miles

Yes, BMW does still make air cooled motorcycles. There has been some advancement recently in coatings used on pistons, cylinders, etc that allow for closer tolerance than the old technology. The air cooled engine is not dead. Before paved roads there was mainly air cooled engines that did rather well for the time. Liquid cooled motorcycles have advanced as well. Both work well and perform their intended function. It would be best to choose some other criteria to pick the right motorcycle for what you want to do as cooling is not an issue. Most people are comparing 20 year old bikes to new ones. Look at the new air cooled bikes.

[@discoveror9576]

I've noticed that air-cooled engines seem to be mostly limited to 250cc and less by the major Japanese and Chinese makers. I've, also, noticed that air-cooled engines are generally run with less/lower compression ... which, in turn, make less power ... no doubt for operation in geographies with poor fuel quality. I note that the (big) Royal Enfield air-cooled engines, which make relatively little power from their displacement, seem to be de-tuned with low compression, also. I've noticed that the higher power:displacement engines (usually running high compression) require the shorter maintenance (especially oil-change) intervals. From an engineering/design viewpoint, it seems like the more STABLE coolant temperatures, obtained with liquid cooling, allow higher compression and the resulting higher power:displacement ... and, probably, higher fuel mileage. Though I struggle with your accent (I still haven't been able to make out your name! 😄 ), I do enjoy and appreciate your videos. 🥰

[@bikesbabes4721]

"For LONG DISTANCE riding"... most riders don't require frequent sustained high performance riding. Going 60 - 100kmh through Africa or South America. Staying around the middle of the rev range, the cooling is more than suficient, the simplicity a benefit and the extra CO2 feed more plants. I rode a GS1200 air cooled all over Africa and enjoyed the simplicity and reliability. After 100 000km, I decided to get a new liquid cooled GS, but the jump in weight turned me down, so I bought a Tenere 700. The liquid cooled engine now sometimes protest by switching on the cooling fan, but other than that, the power per cc is more, the smooth cylinders appear clean, dont catch bugs & mud and, at around 100km/h, it often gives 30 km/litre while the GS would give 20 km/l at the same frugal riding style. Most disadvantages of air cooled engines were compensated for in design and ha no impact on riding. Same with LC engines, but maintenance and vigilance is required.

Exchanged that bike with an Oil/Air cooled R1200GS and when I was going off-road sometimes I could smell burnt/overheated plastics (due to lack of speed cooling was inefficient, but the bike behaved well also!) And now, I own another R1200GS, but liquid cooled. After having two air cooled bikes before, this last one comes as 'something better' simply because nothing overheats. I would not chose air cooled again. Am I getting too comfortable? :p

[@motorcycleadventures]

End of the story!

[@Geshmaal]

Interesting topic, when I'm flushing my coolant I dream of the convenience of an air cooled engine, but I don't often think of the downsides. Perhaps in Scotland it's a decent option as it's rarely over 20C here. It would be good to see you test ride the Moto Guzzi V85TT, perhaps the only current air cooled 'adventure' bike, I assume you'd need a viewer nearby who would be willing to donate theirs for a day though!

[@motorcycleadventures]

I will do it when I have to chance.

[@francis105G]

@@motorcycleadventures That would be great, as I am considering the Guzzi V85TT also. Love your quality reviews!

[@motorcyclesplanet]

My Guzzi V85tt does not overheat even 2 hours in slow moving congested traffic in Tropical heat Philippines , My Z1000 4 in line water cooled gets hotter , Maybe Moto Guzzi Know What they are doing with their Air Cooled Engines , So i Appreciate the Video but maybe modern air cooled engines like The V85TT have Changed These Days , Just Saying

[@johnfountain8588]

I jade a triumph Bonneville in Florida and the bake was so HOT in summer even on a slow cruise along the beach roads So I sold it and now use a Vstrom liquid cool bike

[@motorcycleadventures]

Lesson learned!

[@baltsosser]

I would say water cooled is better for long trips. It gives more consistent performance, and typically better fuel mileage. It is a better choice if you are force to move more slowly, which reduces air flow over an air cooled motor like off road riding. If you prefer road style motorcycles, liquid is better, and notably so...the first time you hit what I call stop and stop traffic. I've taken many long trips with a friend that uses a air cooled machine. On occasion, just because of traffic conditions, his engine temp has read 320 degrees, with 280 being the normal. We have had to exercise what we now refer to as the Tennessee protocol. That mostly consists of taking the breakdown lane and moving that machine enough to cool the motor before it destroyed the ECU. We've had cooling issues just because of traffic even in the cold weather. We've enjoyed riding in Badlands Basin in the middle of June with 124 degrees air temp. As long as we were still moving it was able to work well. My liquid cooled motorcycle has has no issue in any condition we've encountered yet. That may change in the future, but I haven't seen any complications yet.

[@motorcycleadventures]

Thanks for sharing!

[@dazzer4220]

Nice comparison Pavlin....you taught me some new facts 👍. That's also the first time in a while that I have seen you in a traffic jam 😏. Ride safe ✌🇬🇧

[@motorcycleadventures]

Glad you liked it!

[@mototakahe836]

Yet another superb video. The answer why all the mnufactureres are going water cooled is because they listen to you. Or at least they should , look at the latest Kawasaki KLR!!!!!!!!!!!!!!!!!!!!!!!!..

[@motorcycleadventures]

Cool!

[@MrEtnorb]

Mostly academic argument due to the nearing extinction of air cooled motors. Within a few years the Dr650 will be gone, unsure whether it will,be replaced by a modern engine. Certainly Japan is abandoning singles leaving KTM the winner. A big issue is whether your bike comes from Japan or Austria/ Germany. On a KTM I carry a spare fuel pump but a blocked injector is a real problem. Interesting to see that on his round the world travels, Lyndon Poskitt uses a carb equipped KTM rally motor as he can always fix a Carby by the side of the road. Try that on an FI bike in Mongolia.

[@motorcycleadventures]

This will be the topic on my next video.

[@soloveytherobber4124]

Good topic, excellent video. But by the way much of legendary models of adventure bikes are liquid cooled (tenere, africa twin, transalps, bmw gs series and so on). I think that much of advriders vote for liquid)))

[@motorcycleadventures]

Exactly!

[@wonniethepoop7856]

I love simplicity actually without any reasons this is a feelings I can't explain. So of course I prefer air cooled engines as well as carburetors and single cylinder, though it's very rare nowadays, unfortunately.

[@drakeb6168]

I feel that, love my 82 Honda inline 4. Carbureted and air/oil cooled.

[@sidecarcn]

This is very interesting topic. For myself it depends on a few factors. It depends where I'm going to ride. For example Mongolia and Inner Mongolia. If you break down getting a water cooled engine will be nearly impossible. The same goes in other remote areas where there is nothing. Here in Taiwan the coldest our winters get is 15 and thats only for a few days. The average winter temp is between 19 to 25, Summer temps starting in April to early September range from 31 to 35, with the hottest being 39 to 40 for about 2 to 3 weeks in July and August, If I know I'm going to be riding in an around Taipei or other cities I will use my water cooled bike, but I'm I'm going to be in the mountains or riding along the coast where there is nothing. Then I will use my air cooled bike. I remember in 2018 riding in North Vietnam and the air cooled bike I was using broke down on the border with Laos. I was also 200km from the closest shop that could fix it, but it ended up taking 3 weeks to get the parts. If I had decided to use an old BMW R69 there were 3 repair shops and they had parts. My point is if your riding in developing country. Simple engineering is always better.

[@motorcycleadventures]

Ok

[@warrenjoubert4027]

I have a 2011 Honda XR 250 Tonrado, which was manufactured in Brazil. It is air/ oil cooled and is fuelled by a carburettor. It was replaced in my country by the Honda CRF250L, which is fuel injected and water cooled. Both bikes have identical horse power and torque, although the XR gets to this torque sooner in the rev range and holds it for longer. Furthermore, the Tornado is more fuel efficient than the CRF in real world riding conditions (I know this having done a comparison with a Tornado and a CRF on an actual trip). I am not a fan boy of air cooled or water cooled over one another. I also have a fuel injected, water cooled XT660Z like yourself. But I think we must be careful in making stereotypical arguments like being water cooled or fuel injected always provides more horse power, and is more efficient. I must however admit one con of the oil cooled engine in the XR to that of the water cooled CRF. It has much shorter service intervals, perhaps because of the harder work the oil does in having to lubricate and be the means of cooling as well?

[@motorcycleadventures]

Fair enough!

[@ffroutes3715]

Nice video, I am planning a trip to Bulgaria in September with my air/oil cooled 650s bandit. In general I don't have any problems despite having an average of 30 degrees in the summer here in Greece. The only thing that annoys me in the city is the heat that reaches my ankles, this makes riding in the city difficult.

[@motorcycleadventures]

Have fun!

[@86krum]

The water cooled engines are lighter than the air cooled ones? In case of the BMW GS I don’t have to google it. My 2012 air cooled boxer Modell is almost 20 kg lighter then the liquid cooled one.

[@chhiparidersahmedabad.2022]

Engine oil does matter. In India engine oil 20/50 mostly during summers. For better performance of a motorcycle, liquid cooled is preferred.

[@motorcycleadventures]

Thanks for sharing!

[@javandell8020]

Hey Palvin, Best to keep focus on riding than scaring the little girl at 0:23, maybe the laws are more relaxed there than in the US, you would get a hefty ticket if you do not stay at least 10' back and wait for pedestrians to leave the crosswalk here in the US. Keep your radiator cool now...

[@motorcycleadventures]

Well, they do not even noticed that I am there.

[@superwag634]

But a million Honda cub 125 air cooled motors can’t be wrong. Most engines come with air cooled system. And they’re sold into tropical countries mostly. So I don’t think the situation is as bad as you suggest with “most new engines are water cooled”. Maybe in rich countries like Bulgaria they are 😅

[@motorcycleadventures]

Okay!

[@moreaxe9829]

Yah... I wonder why honda make a dirt bike with air cooling system and called it a dual sport, might be a scam but so far so good with my crf150L...👍 Never break down for 4 years now even when i dropped it several times...😅

[@motorcycleadventures]

Enjoy it!

[@paulfairbrass4424]

I have friends that say they love there v twin air cooled engines, i do to. But a couple of years ago traveling from milan to Verona in temperatures over 33 degrees pulling up in traffic and hearing the fan roaring, i thought well at least i don't have to worry about overheating.

[@motorcycleadventures]

Exactly what I mean!

[@G58]

The answer to your last question Pavlin is probably: emissions/economy regulations compliance, servicing and aftermarket profits, and marketing. Giving a tiny Swedish Elf Puppet fewer reasons to cry and hurl blame at everyone who doesn’t ride to a communal city-based organic vertical lettuce farm on a free range unicorn, is of course a noble idea - unless we forget everything we learned about photosynthesis in our first biology lesson in school, and ignore the solar maximum effect on Global climate change... Having said all that, as I’ve mentioned before, the bike I’m designing has a BMW F650GS Dakar engine in a CCM frame. The fuel system is being upgraded from EFI to a Mikuni carb, and so there will be very few electronic devices to go wrong. The main engine sensor will only be used to switch on the fan, with a calibrated feed to an analog temperature gauge. Or I may use a digital gauge that’s swappable between water, oil and air temp. Where hoses are vulnerable, I may substitute stainless tubes. All my CCM buddies think I’m crazy not using a genuine CCM engine. But with the BMW unit I get vastly superior temperature control (as you explained), better reliability and readily available parts, plus DOHC. What I don’t get is a kickstart!

[@motorcycleadventures]

Thanks for taking the time!

[@UndCon]

Only 1 time have I managed to get the fan spinning on my 660z Tenere - that was some hard work/clutch in the forest - otherwize i never hear it and it is a maintenance free system. I changed cooling 1 time - only to make sure I know what was in it, how much antifreeze. so simple. Even Porsche knew watercooeld was better for their rear mounted engines.

[@motorcycleadventures]

Thanks for taking the time!

[@aland.3728]

very informative. I learned alot. Thank you Sir!

[@motorcycleadventures]

Great!

[@amdaglas]

I would like advice on Balcan trip my friend Especially for Bulgaria which is going to be my main destination thank you for your awesome videos!

[@motorcycleadventures]

Have fun!

[@marcalampi5036]

Water cooling isn't always better for every application. Air cooled is simple and nice like a kick starter. Old honda CX610 air cooled car reminded me of the original austin Mini.

[@motorcycleadventures]

Ok

[@avim4896]

I did a 650 Km touring in my Air cooled Gixxer and didnt find any heating issue, I did the same thing in Liquid cooled KTM and my leg was toasted after 100 Km

[@motorcycleadventures]

It is because of the way the engine is constructed and mounted, not because watercooled is bad.

[@sjaakvandam2170]

Awnser to your question is not what you might expect: Air cooled is much harder to get past strict emission standards. I think water cooled is much better anyway for almost all aplications.

[@motorcycleadventures]

If there were demand there will be a way and supply

[@kornfred9087]

I never had any overheating problems with my aircooled boxer-engine, even when riding 2up and with luggage on holidays. But i have an oil-radiator with thermostat mounted and it only got 60hp out of 1000ccm, so its not the most powerful, but it will run on low oktane fuel, which modern bikes cant use.

[@motorcycleadventures]

Most of the air-cooled engines also have oil radiator.

[@MustafaMustafa-uy5xx]

Xt 660r i had it almost 13years.

[@motorcycleadventures]

Cool!

[@darrylmoffett8323]

It’s all about emissions. Governments want engines to run leaner and leaner. If you do this to an air cooled engine it will ping and rattle because engine temperatures. Water cooled engine don’t. Plus a water cooled engines can produce more horsepower from the same CC’s as an air cooled engine.

[@motorcycleadventures]

If there were demand, there will be a supply, no matter how much it would cost!

[@kl9518]

Heated grips. I use to put my hands on air cooled engine while riding on cold days.

[@motorcycleadventures]

Same here!

[@multilingo]

Come to southeast asia, most motorcycle underbone and scooters are air cooled unless it's 200cc above which is a minority.

[@motorcycleadventures]

I was there already!

[@pn3795]

This topic yes I wanted to learn

[@motorcycleadventures]

Cool!

[@leotehlion4586]

Air cooled is just simpler for me. I don’t like liquid cooled because you have to worry about leaks. And once you fix it, it’ll start leaking from another place 🙄
