Will 2008 piston fit 2007

Just got a new leftover 07 & didn't realise till i got home that i was given a spares kit for an 08, will the 08 piston fit in or do i need to chase up the dealer for an 07 specific piston?

im pretty sure it will work. if they have the same bore and stroke then yes.

The 04-08 pistons are virtually identical.

Thanks, i checked the part numbers & they are different, whether that means it won't fit tho i'm not sure, wil see if i can get the proper kit anyway i think.

it will work. i have put an 07 piston in an 08.

Use what you have. It will work fine. Unlike other manufacturers, Honda often changes the part numbers every year regardless of whether or not they changed the part, and using the 08 parts means that you get the benefits of any improvement that they may have made to the part. The 02-08 CRF450 engines are all similar and most parts can be swapped from year to year.
