Hello everybody! I want to fit the newer crf rear hub on the cr 250 03, there is a manner without cut 3.5 mm on the sprocket side?
Thanks

It's pretty much impossible.

The sprocket bolts will be too close to the swingarm and the chain alignment will be off.

Machining 3.5mm off the sprocket mounting surface is not really an option as we're talking a cast hub here that doesn't have a lot of extra material to begin with.

I have a complete cnc hub made to one aluminum block… not a oem hub
