2005 rm125 project bike

I recently purchased a 2005 rm 125 and I want it to make it my race bike. What mods should I put on the bike to make it a good race bike. It already has a fmf exhaust on it. Any ideas thank you

I'd say that's a good start just get the suspension valved for your weight

Thank you

Those things usually come race ready. I'd just do what he said and adjust suspension, maybe chain and a larger rear sprocket for better acceleration out of the hole shot.

What's the difference if I did that or brought one tooth down in the front? Is there a reason you said rear sprocket?

bigger rear sprockets give better throttle response but smaller ones have more top speed stay with stock sprocket in front

Ok thank you
