Four-Stroke

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..

Hi there. Decided to give the four strokes a bit of a go. I think it would be a good choice considering the forthcoming welsh winter mud fests that seem to plague most events. Was just wondering whether the 08 Beta 4t is better than the 08 Sherco 320 4t. What are their strengths and weaknesses ? I've heard the Sherco clutch is a bit of an on/off situation. I know I have left out Montesa in this comparison but I simply can't afford a recent one.

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

How are people who've gone from 2t to 4t bikes finding the change??? Its taken me about 10 hours to feel really comfortable, but a lot of this was down to bike set up!!

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

Hi guy's, very friendly greetings from Germany. I like your Forum very much. We have nothing like this here in Germany. I took my 4Rt from my dealer last friday. The bike is brilliant. Very easy to ride, a lot of power. My last five bikes were been all Betas. Different to the Beta is, that I drive the 4 Rt much more in the first gear. The sound of the 4 Rt is a little bit too loud, when you turn the throttle for speed. Best regards, Thomas

Don't know if this has been posted or not, but it's a pretty cool video of the 4T GG in action.

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…

why dont 4-Art make a 125 it would be top of the list for all the youths becouse of that nice siclencer note it would be a sell out dont you think.

These are some pictures of my Moto Guzzi Special. Based on a Stornello 1969 engine placed in a SWM 1980/81 frame. It's now 244 cc. (original 160 cc). I use it in Classic trials. Kind regards, Arie from Holland

http://www.trialscentral.com/andy/mont1.jpg If it rides as good as it looks the other marque's sales may get plastered by the Honda steam-roller. I'd buy one on looks alone - that is HOT! Now, if they could just get the side-stand and kick-starter where they're supposed to be...!

Is there something to the report from my buddy that his clutch engages too far out from the bar and will not adjust properly. He tells me that the screw has no effect? Someone tell me whats up so I can let him know! MC

got one at last

First thing I did was take the kill switch off, nothing...not even a pop. There's no spark at the plug. Tried new plug and cleaning earth and connections on coil...nothing. I had done one lap of sections, refilled fuel, couple more sections completed. then stopped to walk a section and would not start...not a pop. Not found anything on a search, I guess they usually don't go wrong much. Is there anything that commonly goes wrong wrong on older bikes? mine is the first 05 model.

Evening all. Got my 4rt on it's side and it filter out. Her indoors went to the local road bike shop and picked up a litre of oil. She came back with silkolene gear oil light sae 75. On the back it says gear oil for wet or dry clutch transmissions. Crankcase rating sae 10W/40. Is this right. Chap in shop said it was the right stuff?????

Just looking through the sanifords ebay shop and noticed this beast of a thing! here

I can potter around all day on it no bother,as soon as you grab a big piece of throtle it's like you hit the kill switch. Bit reluctant to start but not too bad, five or six kicks from cold after i'd had the fuel pump out looking for crap, and three kicks when hot. I've give it a basic service recently as I thought it was going down hill a bit. I've put the old air filter back in to check that the new one isn't restrictive,still no joy. No crap in the tank really, just a bit of slight dust. The bike is an 05 and I got a spare throtle body with box of bits that came with the bike,so guess it's had a new one at some point. I'm quite new to the bike,only used …

What do you guys think?

Ouch!.......looks like it's definitely a prototype then!

Two stroke Vs Four stroke traction theory. This is an open letter placing down my curiosity as to the realty of my thoughts of two vs four stroke traction. It is looking at the theory vs reality. Given that a two stroke crank rotates (under power) with every pulse of the spark plug means that every rotation of the crank is under power and therefore no free wheeling in affect. The pulses are somewhat smooth as there is no coasting just continuous power being sent to the back wheel as long as you have the clutch out and the gas on. A four stroke on the other hand has the crank make one revolution without a power pulse and one with. Basically the crank is coasting with…
