YES, finally! Been waiting for this for ages, thanks!

[@BurnRubberL12]

I had the yamaha for a year and I loved it. It took me to college and work through all weather and I passed my mod 1 and 2 on it. Then in the summer I went on a capping trip in the south west with my mate. So really the bike does it all.

I had one For 3 weeks.. Garbage.. Sold it done my test 2 months ago.. Now on a ninja.. Does in 1st what that done top end

[@Chalky.]

The best thing about the old 2-strokes is you could derestrict it while still on your CBT and I knew nobody that got caught, but on these things you're stuck with that weedy power output.

[@AIBETTSYIA75]

HELP! I need a faster bike for Uni as i will be doing dual carriageway riding and aswell as inner city riding. I currently have a Honda cbf 125 and will be doing my A1 this following year. The CBFs lovely but will only cruise at 60 and that doesn't fill me with confidence as i fear it will harm the engine if its done on a long trip. What 125cc would be best considering speed and the fact in 6ft 2inch. Any suggestions or advice?

[@AIBETTSYIA75]

Which one of these would be best for Dual Carriage way riding?

[@Caluma122]

To be honest that's one of the best things about two strokes. Is their insane powerband. It's like saying you'd rather have a non turbo car over a turbo'd one.

[@DJTonko96]

So which one should I buy? The yamaha or aprilia??

[@kmewborn360]

this was awesome thanks, just make them longer please? approx. 11-18 minutes?

[@myfirstgl]

Love the vids guys, but the wind noise in the recording is simply unacceptable!!!

[@Caluma122]

It's not just the top end that two strokes benefit from. Setup correctly they also have lots more power in the bottom end.

[@7starsfear]

Wanted an rs4, got an RX 125 ... it's reliable, easy to mantain and delivers a good amount of power. I regret nothing.

are these 2 stroke or 4 stroke ?

+Crazy Tubex u cant hear it or see it? wow ofc all 4 strokes

[@tubex0214]

do U recomend cagiva mito 125 for first bike my firend is selling one .

[@duramater555]

i would never recommend a 2 stroke for the first bike^^ pls first learn to drive, its hard enough to manage a 4 stroke, a 2 stroke is much harder

WHICH IS BETTER SO?

[@Caluma122]

When on small displacements the extra bang goes a long way!

[@Endle185]

It is what it is. The Honda is the best to learn on so if u get a 125 then u have Prob passed your cbt. U need to know what u r doing before getting a fast bike. The Honda does have good build quality. Mine is a 2008 that sits outside. No rust. Hope this helps?

[@Mrbikertomtom]

I'm not into all these 4 stroke 125 'Sport' bikes, much rather just get myself a 05-08 4 stroke supermoto, probably slightly slower but I'd save loads of money and I'll be doing my test soon after! Win - Win.

[@charliesmith1017]

is the older r 125s faster than the brand new 1s or something?

[@corinoliver5341]

Charlie smith old 125cc's were 2 strokes, new emissions regulations means they're 4 stroke and slower

[@jammykiller778]

Is the rieju standard in this vid

Would have been good to see a CBF 125 or YBR 125 in there as well to see the difference between the budget commuters and these bikes that are nearly double their price

[@Ikarus_Riding]

Well yeah, but there are people that are more worried about it's consume and the money that you spend repairing, than the power at all. I must admit 4 strokes are slow. But with 300 euros you can upgrade to 184cc and you can't compare to the r125 original power. It gets a good boost I'm talking about the yamaha yzf r125 btw, aftermarket stuff come from Itally so it's expensive. Idk about the others

[@SpreadTheLaugh]

what about the daelim roadwin fi or R ? cheap and fast

[@LunaStarFire]

Depends where you live but just check in a local dealership, generally I know the hondas around 3400, the yammy is closer to 4.5k,

[@Genstafa]

On the track, a 120kph 4-stroke and a 150kph 2-stroke is a BIG difference. On a daily basis, however, on public roads, you can't go over 110 ANYWHERE, so it's ridiculous to get a 2-stroke for daily use. A 4-stroke consumes less, less services needed, the speed is enough for public roads, and sounds like every other 300/650 bike. A 2-stroke, consumes 2 litres more, more services needed, you need to ILLEGALLY open your bike to reach over 120kph AND the bike sounds like an electric toothbrush.

[@dhom100]

when it comes to looks, sporty sex appeal, Yamaha is king. the R1, R6, even that little R125 are just gorgeous. I would bet most buyers in this class would pick the Yamaha.

[@moomoodeadcow]

The RS4 looks like a RSV4 and it's a 125cc. I'll probably ride it like a scooter so performance won't matter. You have my vote there.

[@grandicellichannel]

The Aprilia is slow? Of course! You tested the RS4! The RS 2 stroke it's the best: it's marvelous designed, the quality is very good, and espacelly, it's fast as a thunder... Also, the Yamaha yzf it's a good choice, but the Aprilia RS it's absolutely the real winner.

[@MattyRS125]

Theres a major point missed out... the aprilia rs125 can be set up with a power blade giving it around 29bph giving it a top speed of around 105-110mph. I owned a 2003 model aprilia with a 34mm carb etc and to be honest it pulled to about 119mph and 0-60mph took around 6.8 seconds when running sweet. Aprilia wins hands down

[@Minkais]

I'm getting my license this summer, but I can't decide between the Yamaha and the Honda :/

[@vTaZZstyle]

aprilia looll

[@swerazza]

I would take Yamaha allways over the Honda when we're talking 125s

[@Minkais]

***** Too late mate, riding my YZF R-125 daily now and I'm loving it ;D

[@DeadlockTimba]

I got rieju and I have tried aprilia and yamaha but I think rieju is the best one. It's fastest no doubt about that. That guy said that it's handling is shocking but that's not true, it's solid and good enough if you're not driving on track and why the fuck would you? It's cheapest and it's not mainstream. I mean everyone always compliments it how good looking it is and everything. So I think you should buy rieju, it really got the best quality-price ratio :)

[@miguelitolitolito]

you guys are too big to ride those bikes... oh and try and get your hands on a cagiva mito 525 for real 125 madness.

[@TiziM]

at last the rs4. first im a bit sad the dont produce the 2 stroke anymore because it was the best 125cc bike for bikers wo wanna have fun) but ok. the rs4 has the best forks and spring leg (?) and the best breaks. it looks pretty cool and the engine is ok. it also offers most to the customer, a speedshifter bigger tieres (what is important for 16 years old guys^^) and it only has 1 seat (maybe a special edition) but u only need one, its a bike for 1person who knows what he/she wants and can do

[@skunkpireas6364]

so which is better yamaha? i dont understand clearly!!

[@MrMckimmon]

what about the GPR ?

[@Ickxz]

it kinda is, just only in some countries i realized that germany for example got a different system then denmark where i live, but all countries have a 125 cc max class, which makes my comment valid for the question.

[@Norhternbikes]

2900£ not bad ,in Finland yzf-r125 with +4000km cost about 2600€ :D

[@7starsfear]

Becouse the RS series are the most popular 125 motorbikes among beginners.So why is that ? RS are quite simmilar to 4 strokes in how they behave in terms of speed and gas consuimption when downpowered.But as you get used to the downpowered bike you can unlock its true potential only by changing the exhaust system jumping form 15hp to 30 hp.And thats what makes an RS so special,it literally grows with the rider.(IF you are allowed to upgrade it in your country)

[@joshbanham7865]

Do I get one of these or a 125 supermoto??

[@175myles]

Honestly, the supermoto will be more fun with such a small engine size.

[@GratUp98]

it depens, if you want speed over 70 mph and can go for little highways, get one of these, but if you want a bike for going just across city and way more comfortable get a supermoto. But with such a little cc you won't do weelies or stunts. The only way would be with the clutch but if you do weelies with the clutch, you will break the engine... Choose the one you want.

[@175myles]

GratUp98 I agree, with you on the highway part, these buffer the wind at the speed so much better, but the supermoto is the most fun thing, you can go on trails with hybrid tires.

[@joshbanham7865]

Im 6 foot 1. I want to go fast but I also want to be able to go off roading when in bored. In live in the countryside but I will be moving to a city in 6 months. Im thinking a 4 stroke supermoto like a Wr125x as it does about 75 flat and relaible and good fun.

[@175myles]

Supermoto with hybrid tires or a adventure touring bike with hybrid tires definitely. I changed my mind from a naked bike to a supermoto because I found that half of the riding I want to do will be off road as well.
