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).

      ? means I don't know what is different about the new part; if you know, please let me know.

 

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
