Four-Stroke

Now then, is that what you expected? (front page photos of new Mont) I expected not to like the look but am pleasently surprised. If doesn't look any bigger or for that matter much heavier than the Montesa 2T. The frame design looks early gas gas but in Aluminium. I guess the frame had to get smaller in dimension to keep the whole thing small.

200cc 4stroke....cool for a first trials bike...

Have followed this whole four stroke debate with interest but one thing puzzles me, why do 4 stroke engines run at a higher temperature than a 2 stroke when they are supposedly better lubricated and have only 1/2 the number of power strokes. Also why are they noisier than a 2t.

Wheres that sherco 4t thought they were coming in , in Feb james

Hello everyone, I am currently recovering from a cruciate knee ligament operation and therefore I have a bit of time on my hands to do some research as to what trials bike I should purchase next. I also believe that by deciding what bike to get next will help me as inspiration / goal to fully recover and be riding again by the beginning of 2009. I am in my early 30's now and have always ridden 2 strokes (clubman / intermediate level) but did own a 4rt which was sold after 3 months as I seemed to be riding worse probarbly due to me being heavy handed on the throttle. However the problem I now have is trying to predict whether or not trials bike manufacturers will still…

the guesswork ends

Munch was wondering if you have your bike yet. Apparently Appleyards had them to test at Moto 1. sandifords had them at the Scott! My local dealer says it will now be next week before they appear? Wonder what the hold up is now

I'm thinking about buying a 4 stroker any one rode all of the different bikes?? How do they compare??

Can one of the lucky few who have a M4RT describe what changes you or your dealer have made to the bike with respect to the restrictors. I beleive there are three? Are all three being removed? Any pictures or diagrams would be appreciated. And may I wish all of you a great xmas and a happy nerday........ BillyT

Just read the Steve Saunders test on the Sherco 4T in the YOU HAVE USED WORDS OR A PHRASE WHICH ARE NOT PERMITTED ON THIS WEBSITE. PLEASE DELETE YOUR POST/TOPIC. DO NOT TRY TO CIRCUMVENT THE FILTERS IN PLACE ON THIS WEBSITE, he mentioned the old dreaded "pop and die" thing that has affected nearly every fourstroke trials bike (with a carb) that I've been on. Do you get this with the Montesa, with it being fuel injection and all??

Just wondered if anybody has had much trouble with there 4 stroke trials bikes??? i've heard something about a casting breaking inside a 4rt motor??? and rev4 head gaskets?? anybody know of other faults???

Hi all.... Is there any more news about the 4-mont yet e.g price when can i buy one ? and if when will the be some news? Danny

Is it just me or did I miss something birkett said in the test and I quote "..........the suspension was working well especially the rear after the 315r which never did have the best back suspension." Funny how we always get these 'birkisms' last years bike was crap/ let water in/ had wrong gearing/etc but never mentioned the suspension on the mont in the last 6 years anyway as being anything other than ok. The rear unit is adjustable aswell and as far as most fair minded people say its quite good isn't it?

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!!

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…

Would any of you folks that have switched to 4 strokers since 05 consider going back 2 stroke if the price or circumstance was right? What if anything would make you change back to 2 stroke? Aaron

i hate four strokes and thats all im gonna say

Hi, new rider looking to purchase first trials bike since 1983 and am thinking about a new beta 300 and wondering how many things I can do to soften it even more to enable me to learn without feeling the bike is dragging me along. Narrowed down to Beta 300 or Montesa 260. I will also be purchasing the additional seat so I can use it as a general trail bike. other than a slow throttle and fly wheel are there other things I can do? Initially I’d like it very dumbed down. In an ideal world I’d simply buy a beta 200 but I would like to have the option to ride trails 55 year old with zero bike riding since 2000 and very poor bikes handling skills

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