This is the XMR 1000 rear differential found in 2013-2018 800R 850 1000/1000R XMR.

It will fit g2 bikes (500/650/800/850/1000) if you are upgrading you will need to shorten your shaft 1.75″ or buy a kit from us, please see our other listings.

(G1 bikes will require further modifications to work).

This differential has automotive style cut gears, tapered roller bearings, along with an overall larger gear size.

There are a total of three bearings on the pinion gear giving it much more support over the standard rear differentials, this requires a shorter driveshaft, as mentioned earlier if you are swapping this in place of a standard differential.

Pinion spline count 20, standard differentials use 18 spline pinion shafts, that are smaller in diameter. In every way this is a beefier differential.

To bolt your driveshaft on this differential you will need a M10x1.25 16mm long bolt (not included)
