Post by: 49Films on July 24, 2012, 11:59:36 PM
So i rode my 125 3 years (2009-2011) - now im riding a 250f but still use the 125 for practice but changing next year again to the 125.But my 'problem' is that i want more power.
Can anyone of you give me some tips what i could do - any experience you guys had ?

oh yeah  8)

If you're after power in a particular area, I'd suggest getting some head work done. A higher compression piston would give your top end a kick in the arse.  To add on TMKIWIS RM suggestion, someone on here recently mentioned that an 06 RM 125 had awesome bottom, mid and over rev <---- everyones favourite part.

Acually higher compression shines more in the low end, makes it more snappy, but changes the top only a little. I would say get a 250, you wont be dissapointed power wise  8)

One of the members (SuperTrucker) has a LOT of experience with the last of the CR125's. Give him a chance to notice your question and he'll give you more then a few pointers.

x2. But everyones thinking it I'll just say it: Fun factor is off the scale for the zinger that you've got at the moment. Don't get me wrong my 250 is a blast, its lugable and revable and thats all well and good, but the 125s are just... just... You know :P

First: Thank you guys for all your help !
I will never buy a suzuki haha. i ride honda since the age of 12 and my dad is a mechanic for honda so no way.
To the 250 thing.If you mean a 250 2 Stroke.I already tried them but to be honest - this is not one of this bikes i want to ride.Too agressiv and not fun to ride.
But thanks for the tip to SuperTrucker,i will contact him.

PS im so excited for my next 2 stroke projekt haha

All the Japanese manufacturers made good two strokes. I wouldn't discount the suzi just because you've always ridden Hondas or any other brand for that matter. I mean the Hondas are great, but so are the Suzukis, the Kawis and the Yamahas. I guess what I'm trying to say is keep your options open. In the world that is as excrutiatingly competitive as the 125 motocross bike was when it was still in production by the big four, all those bikes were really great. They had to be. If one wasn't very good no sod would buy it.

To clarify, I am aware that Yamaha is still making their YZs I was just generalizing.

Quarter litre two strokes are pretty hardcore stuff, no two ways about it. If you don't like the 250s thats totally understandable, Mine has scarred the pants off me more than a few times :P But I'd also add that with a heavier flywheel and a swapped out power valve spring, they can be mellowed out alot if that helps. But I'd stick with the 125. Such golden fun. Hell I rode mine up and down the road and couldn't wipe the smile off my face :P
