In Stock trim the CRF is a tad under powered.

Remember Motor is 5% and rider is 95 %

ok thanks, would a white brothers exausht (dont know what model) make much difference to the CRF

Actually a few tuning mods wake up the CRF. Jetting, Hi comp Piston and a Pipe in that order. Search on Pipes you will find a few really make a difference. The pipes are less effective on the RMZ or KXF from what I have been told.

Our Modded CRF will run with the rest all day and actually out pull most of them but it is up to Junior to make it happen.

The two cheapest/best performance you can do to a Honda CRF250R is to buy a boyeson Quickshot Accelerator Pump and a ICAT. Byeson QAP prevents bogging and the ICAT improves bottom end a lot.

I am looking at getting a second hand CRF 250R adn its only got a white brothers exaughst on it and not the other two mods, will this effect the bike like make it run bad or anything. should i look at dooing the other mods aswell because it has a pipe. Thanks for all your help guys

Dude... you're going from a 230 to a 250F and you're concerned about power???

Byeson QAP prevents bogging

So does wringing the throttle.

...and the ICAT improves bottom end a lot.

So will a larger sproket.

Does the CRF come with a spell check?

I am not concered about power just about only having only a pipe not the other mods like pistons etc. will it effect the bike like destroy it. but thanks all for your help so far
