Four-Stroke

Where is the engine serial number located on a Honda TL 125 made around 1980? Thanks

What do you think about riding gear, I must admit now i am a bit older and rounder,lycra skin suits arnt quite so smart looking. But i think i have found the perfect solution, the big supermarkets do brand new jeans for

What do you think gas gas will say now the 4rt is the worlds best trials bike there will be loads of people saying raga could of retained his champs if the final round had not been cancelled i feel sorry for bou he has been short changed,the spark has been taken out of his win, When he wins again for the next few years lets hope there will be no contraversy

Well, they are just round the corner.... will the new FOUR STROKES be a plus for our sport, or are they gonna drown the smaller manufactures and tightening the market, resulting in spiraling prices??? The flag has dropped...

it will be interesting to see this bike ,it sounds much more like what was expected of the new generation 4ts

I have writen about this allready on another page RE500s hot start mod on the sherco 320 4t has absolutly transformed the hot start issues with my bike for no apparent reason my bike would refuse to start ,sometimes taking 20+ kicks now i still try and start as normal but you can tell if it is having a funny 5 mins lift the hot start open the throttle a little and one kick to clear next kick starts i have even turned it upside down when really hot let the motor stall and it still starts if you have not done it do it NOW

Did the FIM drop the four strokes only ruling indefinatley? Is it in affect in other countries? I think I read no two strokes can compete in Japan .

As the title says what are the differences between the two bikes technically and aesthetically ?, I'm moving towards buying one second hand so any information would be greatly apreciated. Thanks H..

I am right in thinking that a 4 Stroke engine is normally used for speed, rather then power? So if a four stroke engine is tuned for speed, if it would be used for trials it would be untuned to get a mixture of both power and speed? About the other topic of hating the four stoke, what that all about? They might not look the business, but when it comes into riding they MUST be better or near as good as the 2 strokes. They have to be, riders can't go back down the ladder of technology, after all its taken years to get up it since the 1980's when 4 strokes were in, now with it being in 2003 the technology is far better then it was now. We have a greater understanding of en…

fugi wins again could a fourstroke win the world champs in only its second year? everone was verry vocal when they came on the scene,but now theye are giving raga a run for his money its all gone quiet. come on fugi (prefferably doug but fugi will do)fly the fourstroke flag HIGH>>>

Just read artical about the future of the fourstroke, and wondered what sort of tripe you could come up wi bet it's nowt to do wi bikes

Yes I have ridden all so far, good and bad within the lot, but one thing is for sure, a carburator has its limitations, specially on a four stroke, it is simple physics, and has all been done before. You will not be able to ride it like a 2T, end of story! It will spit at you, and at the worst moment! 250 cc will work for the average rider, which may just be the 200cc = of the 2T which most need anyway, but Sherco and Honda both figured out early on that it would not work in WTC competition. Scorpa has already proven that it takes 150cc in a 4T to really make the bike move! Roumours have it that the Gasser 4T will have a flat head motor, not sure the displacement, I wo…

will they be up tomorrow as it breaks cover at the munich show

I have a 2011 Beta Evo 4T gearing question. I find first ok but second and definitely third way to tall. What do people do, drop one tooth to a 10T on the front sprocket? happy for any input

Hy 4 RT riders I am a happy 4 RT rider since November. I just heard from my local dealer, that I should be careful and never let the cicker lever snap back, it might cause a nasty hole. A new and stronger stop screw should be fitted in, but needs drainage of oil etc and some hours of work, done by Honda warranty. Otherwise I m a very happy clubmen rider, like the power delivery of the 4 stroke and the injection. After 6 years on a Cota 315, I don't want to go back to 2 stroke (except for twinshock trials of course...) So, take care after cicking and ask your local dealer about this problem. Pat

Montesa 4T vs. Sherco 4T (animated gif)

Took air filter out to clean and noticed engine oil? in bottom of air box. This was after running all day. Any body any ideas.. Its not filter oil, defo engine..

Noises off…… The precision click of a Parker 25 ballpoint pen. The sound of a Snap-On ratchet tightening a bolt. The rope winder on an ocean going yacht. The burble of a V8 engine. The sharp crack of a Montesa 4RT engine. The irritating high pitch whine of a lone mosquito in your hotel room in the dead of night. Emotive sounds each and every one. Think back, if you will, to bikes and cars you have owned or aspired to own. Then identify which of them you were most attached to and hold the fondest memories. Then ask yourself why. I remember vividly my first push-bike with proper tyres. Passed down from a cousin who had outgrown it and still a little too big for me …

Everyone is going to have one, right? When does it look like we will be able to see one?

Hello, afther a 2017 Beta 250 factory 2 stroke i bought a 2017 montesa repsol 260 becouse i love the look off the bike. Yesterday first day at the montesa and i must say it was hard to ride. I will give it a while but when changing back to my beta 250 it felt super light and super responsive. Zapping over a log, turning, hopping,....have to learn all on the montsa or....stay with the beta. Greathings, Luc
