It is recommended to flush the oil after the first ride to eliminate particles generated by the gears first meshing and break in. Taking cover off to remove all particles is recommended versus only using the drain plug.

On a normal basis, change the oil at the same time as transmission oil.

    Fit and finish is excellent. Function is perfect! Starts my bike faster than any Euro bike I’ve seen so far! It has changed the way I ride and made “Hard Enduro” possible on a MX bike.
