Fitment
Honda CRF450R 2002-2008. Verify exact model and year before ordering.
This is a better quality gear set than OEM, the installation instructions are clear, the fit is perfect and the shifting is smooth as butter.
My reason for replacement was due to my second gearbox failure and I wasn't keen on putting the standard stuff back in.
The gap between first and second is slightly noticable, due to first gear being part of the mainshaft and having the standard ratio but other than that I prefer the wider ratios for my riding (desert).
I only have good things to say about this product and strongly recommend it.
