2009/2010 throttle body on 2011 CRF450R

Hi,

Will the 2009/2010 CRF450R throttle body work on the 2011 CRF450R?

We're looking for more top-end (beachrace).

I know Honda changed it from 50 to 46mm, but my concerns are whether it will fysically fit and will work with CDI, etc.

Thanks! :thumbsup:

fits,needs remapped.

Ok. Can you say anything about why it has to be remapped?

because the air flow is drastically different between the throttle bodys. the same reason you want to switch to the 50mm body.
