Stock is 76.8mm and big bore is out to 79mm making it 264cc and the results are great! Big power gains for low cost in the new CRF250R with no fuel mapping changes.

The Honda 400 motor is proven but can just use a bit of a boost from a cam and piston. Hot Cams and CP took care of that with a FMF pipe.

MXA August Issue

Posted by Jay on 15th June 2009

Check out the upcoming August issue of Motocross Action Magazine to see a full test on the 09CRF450R made into a 469cc monster. Great help on this project-thanks to all and especially Tokyo Mods. Just saw the article and not as good as I would like as they felt we had too much bottom end. However, a great build. mxa-crf469cc

Project 2009 Honda CRF250R

Posted by Jay on 17th February 2009

Nick Lytle project AX CRF250R

Nick Lytle project AX CRF250R


For this TWMX project we built up a CRF250R into a full blow Arenacross pro level race bike. I didn’t of course have a full blown pro level Arenacross racer so we did the best we could and kinda did a extreme home make over and let made the dreams of a kid from the Menifee hood come true. Nick Lytle was able to race the bike at the Fresno round and then again at the other two Western races. Hopefully the next two go a bit better and he can make it to the main. So, far too much rain has been a problem as he can’t get any A practice and he is finding the whoops are a big area to make up time. Tokyo Mod, MB1, CP Piston and Hot Cams were all huge in making this project happen (oh and his boss at his part time slave working job with Parapros).
