FRONT SPROCKET NUT AND WASHER KIT.

NUT:

New, thicker front sprocket nut for the gearbox output shaft.

YAMAHA changed thickness from 8 mm to 12 mm what prevents nut from unscrewing or damaging its thread.

The thread is nominally 18 mm in diameter, with a pitch of two threads per 1 mm (M18x1 mm).

The same quality as OEM, made of the same sort of steel and in the same technology.

WASHER:

Front sprocket washer lock. High quality product (some say  the product is even better than OEM) and it is made of:

-       - 1 mm thick galvanised steel

        -  Fits tight into the output shaft
