CRF250X changes from 2007 to 2008
January 6, 2008 version
Changes for 2008 include:
- New works-type front and rear brake discs reduce unsprung weight.
- New Dunlop 742FA front tire for improved turning feel and traction.
- New narrow-design fuel tank for improved rider ergonomics.
Here are the differences, in Parts Catalog order. If a part is different between 49-state and CA, each number is shown. If they are the same, only one number is shown. Many of these new '08 parts will work on '04, '05, '06, and '07 models; check with your dealer (yeah, right).

Cooling Fan Kit
The Cooling Fan Kit previously available for the '04 through '07 models is not listed for the '08 model. This does not necessarily mean that a kit cannot be fitted to the '08 model. The right radiator, which has the fan mounting tabs and thermostat tap, is unchanged from previous years. The '06/'07 kit had extra components that allowed it to be fitted on '06/'07 models even after some electronic components were changed or deleted starting with the '06 model. The '06/'07 kit should work on the '08 model, but you may have to run extra wires to the battery hot/ground (the wire harness is changed on the '08 model, wiring to the battery and a connector were probably removed.).
Notable unchanged items include:
Cam
Valve assemblies, mostly (valves, valve springs, valve spring seats, valve cotters, shims unchanged)
Cylinder and gasket
Clutch plates and clutch springs
Exhaust pipe
