Could A 4 Stroke Be BETTER for Hard Enduro???

[@dirtbiker4376]

I actually have respect for you Rich, due to the fact that you primarily ride two strokes (as do I), but you brought out very valid advantages of the four stroke. Some people are so stuck in their opinions, they refuse to accept anything else. I find your reviews and opinions very unbiased. Bottom line, ride what you like, have your opinions, but for crap's sake - let other people do the same!

[@IRCTireUSAMoto]

Completely agree! Thanks for watching brotha!

[@marcel7161]

I am the other way around. I own a 350 EXC-F which I use for enduro cross and for training purposes at the MX track. When I want to ride hard enduro, I fly to Romania and rent a 2 Stroke from Gold Class rider Rienk Tuinstra. I once brought my 4 stroke and it simply not suitable enough for hard enduro.

[@2WheelDerness]

@@marcel7161 well...I am also from Romania and have a friend with Xr400 with slightly updates, but it goes where majority of us with 300 2strokes cant go. So I really think is about training and experience. I also love the engine brake of 4stroke, something I've been missing a lot. In trail riding I think that I would be lot faster on 4stroke (dont have a tpi so I hold the clutch quite a lot and is anoying). (Edit: we are not Gold Class )

I've been 2 stroke for years until I tried a 350 4 stroke xcfw, now excf and all my buddies thinks I ride much better and faster plus it doesn't tired me out like the 2 strokes. I feel my 350 has any power you want until you open her up hang on. I'm liking the 350 pretty much. I like 2 strokes but what fits me best I'll stick to 4.

[@IRCTireUSAMoto]

Great thoughts! To each their own!

[@moreliquorinmycoffee]

Perfectly explained, What youre basically saying is that yes, when it comes to the bleeding edge of hard enduro ability, the modern 2 strokes are better, this would also be reflected by the fact that all the top hard enduro athletes use 2 strokes, but with that being said, to the average enthsiast, even maybe a bit more of a hardcore enthusiast, pick whichever one you like because really they are pretty much equally capable to the average rider.

Hey Rich awesome review! I've been a maintenance technician for over 40 years and there's an old saying.. the right tool for the job! The bike that works for you, it's the best bike to have.

[@avz46]

Thats why I got my 450fx yamaha from a 2017 xcw300. The ktm 300 shines in slow speed stuff, but I find im faster over all on the big 4strokes. Our events are hare scramble type stuff with some hard enduro sections. If it was all hard enduro, I would have stayed with the 2T. I find most 4T more stable and controllable when trying to keep your over all speeds faster. gearing is more important on a 4T particularly in 1st and 2nd in order to be able to tractor over technical terrain at low rpm.

[@cokecruzb]

Completely agree! I have a 300 2T and a 450 4T and both are great for different reasons. In loose terrain (sand, very dry dirt, leaves…) i find the 4T much easier… also in fast rides. For me the only place where 2T shine are river beds, with lots of boulders, or very steep- very slow rock climbs.

[@bikesbeersbeats]

I also race harescrambles on a 2T 300 and the 4T riders definitely seem to have an edge as so many of the races are wide open fast sections vs technical woods riding.

[@mmaaddict78]

I tend to dual sport a bit more than straight trail ride because over the years more and more trails around me are being closed. The 350 makes stretches of road between trails much more bearable. I think a 350 is a much better all around machine, but if all you want to do is hard enduro, the 300 is king.

[@b2ridez279]

Saw several 500s at the first Grinding Stone hard enduro. They finished a lap and had some advantages: Tighter lines between rocks due to the smaller pipe, and the traction on sandy rock seemed better. 4t digs into the earth vs 2t spins on top (better on loose hills as it keeps forward drive). A give and take, but 4t is better in 90% of terrain… it’s that really hard 10% the enduro 2t shines.

[@0xsamgreen]

Great review! I'm in California where new 2ts were banned last year, and you can only ride newer 2ts half the year anyway. By the time I wanted to buy my bike last fall, the only one left was a 500 xcfw. Since I bought it, I installed a G2 throttle tamer and a Midwest clutch lever. Those made it way easier for me to practice slow moves. Please don't hate, but I'm going to put a Rekluse on it to prevent stalling.

[@BRAPMXLO]

Rekluse are great on four stroke, in my opinion useless on two stroke

[@Bigtymer781]

I live in California and 2T's weren't banned. Actually you can ride red sticker 2T's year round now. All off road bikes starting in 2023 and newer are banned, regardless of 2T or 4T.

[@twowheelpilot]

100% agree with all your points. I'm on a 2021 WR450 now and it's epic right down to just off idle at the point of stalling. It's incredibly tractable and map-able with the power turner. For ultra clay, full lock to lock steering situations trying to get up stuff I'll say the two stroke wins. Everywhere else I'll pick the WR450. I've taken this thing everywhere from clay snot to river runs. I'm hugely impressed where it will go. When is Yamaha going to give us a WR250/300E with six-speed gearbox balance shaft in a carb. E = electric start

I must say this video ( and the comments ) helped me some. Many years ago ( 1996 ) I was a very fast local expert rider locally . Formerly in the early 80 s i raced motocross and did very well , but life changes and I had to stop. When , later I saw " scrambles" I really wanted to give it a try as I grew up riding forest . I was near broke at the time , but i found am old 1980 KDX 175 ( Needed a crank ) and a 1981 KX 125 chassis . I installed the MX suspension on the KDX and entered my first scramble ( 4 hour partner event ) . The track owner took lap times the day before and apparently i set the fasted recorded even though I was just having fun... but it was the expert class for me. opps. We got a second in that first event ( my partner was a whiner and would drop down to 3 rd when he was out , making me have to catch up in my shifts ) After I rode all the team events alone and won all of them ( all scrambles were 4 hours in length ) I loved beating the new machines on my old Frankenstein Kawi . I once rode a xr 300 ( thunper racing kit) in a national and won my class but found it more difficult in the tight stuff . Now retired and about to move to Thailand in 2 years , and I have been invited to ride scrambles by some local chaps there. Most ride KLX 140 s and have a blast with those . They said I have to ride bikes like theirs , and while it would be nice to do this on a reliable , cheap fun bike like those , part of me wants to enter and win.. The thing is , I will be 58 yrs and since i have not ridden in many years , its unknown if my fitness and skill will come back . I think a competition 4 T is out simply because of the blazing hot weather there often . So many in the comments say their comp 4 t failed due to heat . These guy's KLX 's survive because they are not highly stressed race bikes . During the rainy season the tracks are often tight and technical but also have some seriously massive long hills . Yet , that bug in the back of my brain to win is always there. After seeing this video I am thinking of a 200 cc 2 stroke with fuel injection and electric start . Importing into thailand is out of the question due to the 200 % import duty BUT there is a KTM dealership near my wife's house there . My preference would be an air cooled 2 t enduro racer but none are made anymore .( less things to fail and lighter weight ) Hmmmm. Maybe i could restore an air cooled KDX 200 and ship it. The duty on an old used bike would be more manageable . As you can see , my mind is still all over the place on this. haha But thanks all for the info.

I have been buying and riding new bikes since the 1970’s. Sometimes old ideas die hard. My 2021 KTM 500 XCF-W weights 234 pounds dry. My 2024 Husqvarna TE 300 weighs 235. No misprint. The gap between 2T and 4T bikes has really narrowed in recent years. Even the power delivery has become similar. The 2T bikes still have a lower center of gravity and feel lighter due to the reduced reciprocating mass creating less gyro effect. They also ( importantly) are more stall resistant at low speeds. But my 500 makes more bottom end torque, has a broader powerband, and is 20 mph faster. The big 4T bike finds more traction than the 2T bikes in slippery hard enduro conditions, and the motor is good for 800 hours in normal ( non racing) service. A big advantage for me is the extended range: I can go 40 miles further on a tank of fuel. Enjoy both types of motos while you still can. They will soon be legislated out of existence and you will be stuck with your Ebike with a dead battery miles from anywhere.

For me, in really tight singletrack (regardless of technical difficulty) the 2t is much easier to ride, feels much lighter, and takes a lot less energy and effort. I just switched from a 350 excf to a 300 and I am in love. I come from a MTB background and I'm pretty new to moto and I just immediately felt more at home on the 2t. I think it really comes down to this in all riding (doesn't have to be hard enduro)... 2t is light and nimble and 4t is heavy and stable. There are advantages and disadvantages but I feel much more confident in tight singletrack on the side of a super steep hill with the 2t. I'm not fighting the bike. I'll trade that for higher speed (30mph etc) stability as I ride lots of singletrack in northern Idaho.

I have a Husqvarna TE310R (last year before KTM) and I am still getting used to my Beta 300RE.

Unfortunately, that Husky cut its own radiator hose and I must have warped the head.

I honestly prefer my 2t 300 beta great engine for enduro but has 4 stroke is for the faster longer rides that’s where a xr250r comes in handy can sit at 60 mph all day happily and does well in the forest 🌳

[@dpforth]

Factoring in maintenance demands puts a big checkmark in the 2T's column.

[@IRCTireUSAMoto]

Interesting!

[@donaldgrant9067]

Well done article and I won't argue with you about it. I prefer 2 strokes, but someone else may prefer 4 strokes. I guess it is like boxers and whity tighty's. Of course the 2 stroke are the boxers. It is freer to work with.

[@robsonenduro3316]

Sure we can, Graham Jarvis won once Romaniacs on 4 stroke. Super enduro events are on 4 stroke mostly. My only problem is I stall more often on 4 stroke then on 2 stroke:)

[@IRCTireUSAMoto]

There you go! 🙌

[@tuomashayrinen4763]

I've ridden both, from a 200 2 stroke to a 450 4 stroke. Most important thing is that a 4 stroke heats up easier. Or actually really fast. A fan is compulsory and I still blew a radiator hose from a 390 Beta. So for slow speeds the 2 stroke rules since it won't boil so easily. Otherwise it's just potatoes or tomatoes. Sure the 4 stroke weighs a bit more and has more rotating mass, but also tracts better. For high speed cross country or GNCC style racing I like a 4 stroke since the weight and the traction stabilizes things. For slow stuff a 2 stroke is better since it won't overheat so easily and is a bit more flickable.

[@babar69110]

keep oem exhaust and put a race map... red rubber grease your water hoses.... Onsumer i'm used to "try" practice slow wheelies by 40 C on my 390 rr . Sometimes yes fan switches on, but that's all except to the point of black burnt metal clutch disks ! ;) You need too to put a + 200 rpm map, water pump runs faster and it seems a paradox but yes , bike runs cooler too

[@jaynen]

So is two stroke going to be easier to "learn" low speed riding on? I moved from West to East and of course out West lots of open trails, desert, dual sporting etc where the 4 strokes were king, but now I am out east in NC and its more tight woods however hare scrambles still look to have some higher speed sections

[@tomasfaure1415]

Hey rich, i have been in a debate myself, i i am between a 250 and 350 four strokes, (both) for a bit more of faster racing, waht do you thing i should i consider when making a choice?, i like to ride the dunes and fast enduro races, but we also ride mountains (not hard enduro but very steep) thanks this video helps alot

[@IRCTireUSAMoto]

Sounds like a 350 Will better suite you’re style.

[@adampetten1009]

I bought a 450rx and it's a great bike but too much power and hard to control at low speed. Maybe a Yami wr or 450FX would be better with wide ratio. I had a YZ250 and loved it. I'm really on the fence of of getting a beta 300 x trainer. I do now realize the honda 450rx is a motocross bike with 18" wheel and kickstand, but I'm trying to get it more of a woods bike. (But would even think of taking it on hard enduro.) The near 0mph I think you are bang on!!! That's where I dislike my 450RX, I have geared down 2 teeth and will get my suspension made softer, after that I'll try a recluse

[@martinzorro640]

Hola Rick En mi caso estoy muy contento con mi Husky TE300. Pero en caso de cambiar a un 4T, sería algún modelo 350. Concuerdo contigo plenamente. Saludos desde Argentina 🇦🇷

[@TwoWheelsMakesFun]

Do you guys riding on a 150 tpi 2t? I'm rather beginner rider, don't drive on high RPM all the time but I need to change piston every 40 hours. Is is normal or something is wrong? Riding on a husqvarna te150i 2021. The oil pump gives 6 ml of oil for 60 seconds when i put it in pump deaeration mode.

[@brianlafollette7530]

If you look at fuel consumption the reason 2 stroke runs cooler is because it is basically fuel cooled.

[@evanwilliams6352]

Never even thought of that. Makes so much sense. My old 2 stroke is always cold when riding with slower riders and it’ll burn a tank of gas in no time!

[@gophop]

They have lower compression, as well.

[@logandaysh7447]

I ride an old 2002 honda xr 250r that does enjoy the low end rpm and has torque for days and I also have a 1984 honda reflex tlr which is an old 4 stroke trials bike which arguably has more torque than my 2 stroke 2007 sherco 250 but they both have their pros and cons. The 4 strokes have their cams which add a lot of weight at the top of the motor and the 2 strokes in my personal experiences on older 2 strokes 60s to 2000s that if you dont hold them at revs the have a sever case of oil starvation. I am getting back into the world of modern 2 strokes and 4 strokes and love them both but I do pefer my 4 stroke honda xr over the 2 strokes

[@DougNMarcum42]

Nice vid.I think you are right as the bikes 2 and 4 stroke are way more cabable than 95 percent of riders.just preference really.

[@forcedconvection]

Thank you for this video. I've been debating between a Ktm 300 XC-W and a 500 EXC-F. Being street legal out the door had me leaning towards the 500 for greater versatility but had concerns about the super slow hard Enduro scenarios. This vid eases my mind. Do you think the radiator fan is enough to control temp on the 500 in hard Enduro scenarios?

[@IRCTireUSAMoto]

Maybe two fans. 😂

[@chrisoffersen]

@Yo Joe I just started the same journey! The snow’s still melting here in the mountains, but I’m really looking forward to seeing how this 500 does in the tight n twisties. It absolutely screams down bumpy fire roads, and just plain roads, but yeah… wondering how it’s going to do in rocky single track.

[@chrisoffersen]

So, I actually had a choice between the 500 EXC-F and the 300 XCW TPI and, after a couple days (there’s not much time to think about a bike purchase here… they’re usually sold before they hit the floor) I chose the 500. I’ve got to ride 20 minutes or more on pavement to get to good trails, so that was a major consideration. In Colorado, 2 strokes can be street legal, and it would have cost ~$1000 to get that 300 up to code… but, buzzing down a road on a 2t …meh. I still wonder what this 500 is going to be like in technical trails… but it’s been a blast everywhere else so far (after break in of course).

[@chrisoffersen]

@Yo Joe Ahhh Thanks for the heads-up. I'll have to start practicing some front-squats!

[@oly10676]

I ride hard/extreme enduro on a 2007 400EXC (RFS) since i bought it. What eventually worked for me for overheating was the use of Evans waterless coolant and also trying not to over-rev the engine when slipping the clutch in the very technical stuff. Lower gearing helps for the latter (i use 14-52). Before that also used a radiator fan (with a stiffer radiator cap) but removed it as it was not as efficient as the waterless coolant, added weight and in very technical rides and hot weather it drained the battery. Needless to say you need a sticky tire for super slow hard.

[@akathecanadian]

Especially with KTM building both stroke bikes so similarly, it’s really down to the rider what they can and can’t do on a bike, I ride an RMZ 450 and my friends ride Yz250x’s. We can do all the same things just I struggle more in some places, goes both ways

[@brentcarlson7796]

Remember when Letti Sr. won Romaniacs on a 4stroke BMW? Good point on the skill of the top riders.

[@IRCTireUSAMoto]

Ha ha! The big 450!!

[@Shultzchet]

I have a 2019 350 exc-f, and I believe it is the perfect bike for me, let me explain. I ride primarily desert races with some sprint enduros mixed in there, but because of the mostly high speed desert terrain the four stroke it probably better and more stable. I enjoy very technical terrain but like you said the average rider is not an expert, im working on a double blip and I could probably do it if I had more time to practice, bit needless to say I am not running nearly at the limits of this bike in most situations. I will say though that they do get hot, my fan frequently comes on even in the "high speed" trail riding in the heat of the desert. This usually happens most when trail riding in the spring and summer, and the races in my area they rarely hold in this time, if they do it is a shorter high speed race like a dual euro because it gets over 100. The only downside to the 350 exc if the power, it wouldn't be too difficult to fix this but I live in California where that is illegal, but racing desert i frequently find myself doing max acceleration and having another 15 horsepower would probably make a big difference because im racing with the 450s. My dad has the 350 xc and there is a noticeable difference in top end power, but there is also a big difference in tractorability, mine likes the lower rpms going up a hill much better, wich is why I thing the 350 exc is a excellent all around bike, for a loose hill climb the xc would probably be better than the exc just as far as pure uphill drag race style. I did try a 300 two stroke once, it was certainly different, not better or worse just different, it definitely felt lighter, but then again at the time I had my dad's old 03 450 mxc with like a 3 gallon tank on it so it was a pig. When I got my 350 I knew I was going with that engine because my dad had the 2018 xc and I raced it a few times, but what led me to the exc was being able to ride it to college and work, as well as across town more easily to hit the trails on the other side, my dad also has a 500, but I knew I didn't want that heavy of a bike. But I'm glad I went with the exc instead of the xc because the difference other than max power like gearing are very nice.

[@artsteale3443]

Just buy one of each. Four stroke for the faster stuff and a two stroke for the more technical stuff.

[@IRCTireUSAMoto]

That’s pretty much the conclusion….. they’ll hang you for it though… 😂

[@aaww2459]

I was wondering where in Ohio you put on the class? Also, do you still do them? Thanks

[@ofekzfoni211]

You would even like the 350 4t more if it was not tuned! The way it comes out from the factory is perfect for hard enduro. The motor doesn't stall so quickly. PS I love 2T but would live with the 350 happily

[@jayeye4798]

Really great analysis by the guy who doesn't love to talk! Boils down to seat time, baby!

[@riders.oregon4474]

I have a 250 TPI 2 stroke and a 250 4 stroke, both modern. With my mostly single track (with some big hill climbs ) the piston rings wear out faster on the 2 stroke.

[@IRCTireUSAMoto]

Interesting!!

[@KoltFin]

That's pretty much what I've seen. 4 stroke costs more to rebuild but it lasts twice as long.

[@Andy-co6pn]

The ports in the 2 stroke cylinder gives the piston rings a tough time

[@bikesbeersbeats]

Yep. Mine failed and destroyed the cylinder.

[@GeertTheys]

Buying a yamaha yz250fx because is more versatile. Can go on a track or fasttrail rides and also do some hard enduro. I'm building my own enduro cross track....

I love my 450 enduro bike for technical riding here in Ohio. Man I wish I knew you were coming to my neck of the woods, I would have loved to take your class!

[@IRCTireUSAMoto]

I’ll be there again I’m sure!!

[@martinfoster5163]

Very interesting video. Personally, and completely outside the topic, I've gone electric for my enduro/trail riding. I'm not a competitor but I do ride technical trails. I find the torque from zero very good on my Surron Storm Bee. Traction is pretty good, stalls don't exist and the torque is excellent. Another issue with 2 strokes is they are obnoxiously loud. I live in the mountains of Mongolia and there are a lot of grazing animals and herders who'd probably shoot me or get very ticked off if I scared their animals or interrupted the serenity of the mountains. I can race around (not silently but far quieter than any petrol engine) without bothering anybody or go near silent by creeping along. I've no idea of electric enduros will ever compete against petrol engines. Their limitations are range and weight. Mine weighs 130kg because the battery is 30kg. When power density increases, weight can go down. Or a lighter weight battery could be utilized specific to the distance of the race or if pitstops are allowed, swapped out.

[@TS50ER]

3:39 Is that true? A modern four revs quicker than a two?

[@shannonscott5788]

I’m better on a 4t doing anything. I’m almost 50 years old raised from big bore 5002t, Honda/kx. 2t are fun but when it comes to winning races I’m faster on 4t. Also my experience is my 4t engines do last longer then all the 2t I’ve had so I don’t totally agree with this video. I will stick to my 30 year experience rather then someone else. I must admit that 4t in the 80s/90s were heavy slower machines but not today.

[@dougderby9454]

In the earlier enduro cross days. Many tried to adapt the 250f instead of the 300 two stroke. Outdoor hard enduro. Hard to beat a two stroke.

[@silvervine6823]

Thanks for the video. I agree completely.

[@keshmo12]

I always look at someone like Pol tares on his big yamaha T7 doing hard Enduro stuff. For the majority it's the riders ability. This past desert race I got passed by a ktm 1290 adventure bike. That guy was a beast though.

[@IRCTireUSAMoto]

That’s a great point!!!

[@IDAHOJAKE]

when riding my kx450f with 2 stroke guys on technical single track. My 4stroke overheats easy without riding fast to cool it down. I’m nervous about 2 stork because I’m 6’4 265 lbs but seems newer 2s can handle all the power I need. Many say 450s are to big. I disagree. I’m big and been riding a 450 for 15 years. Maybe I need a 2s 350

[@ShadowsFirst]

Hey Rich, how do I get into one of your training classes?

[@JDRELGOR]

Surely it's down to rider ability and bike set up, including tyre choice ect.

[@motominded5275]

Good video! I don't think there is an inherent problem with 4t platform, rather how they are currently built and designed. I think a manuf could easily build a hard enduro 4t....heck, my 2018 Montessa is unbelievable, virtually stall proof, so it's not a technical problem with 4t. I think a longer stroke, slightly heavier flywheeled, 300f to 350f with a larger fan would be amazing...but of course, trade off is broad power and hp up top. I know KTM 350s have finished Erzberg in one piece under legit riders.
