Fabricated from 4mm 304 stainless steel, these brackets provide solid side support for the QS138 90H mid-drive motor. Note that you will also need to use/adapt the rear mounting bracket that comes with the motor to prevent movement or rotation under high torque conditions.

These brackets are known to fit the following dirtbikes:

2007 Yamaha WR250/450F
2013 Yamaha YZ250/450F
2009 Honda CRF250/450R

We also have versions for:

2009 Honda CRF250/450X
2010 Kawasaki KXF250/450
2022 Honda CRF250/450R

This list will be updated once we confirm fitment on other bikes.
