Anodised aluminium block that bolts to the engine plate behind
the countershaft using the 2 screws provided. The countershaft
can then be adjusted using the long bolt and locking nut. Can be
mounted on either left or right hand side of the bike and can be
used in conjunction with our countershaft retainer kit to ensure
that the primary chain never tightens up. All th bolts are high
tensile steel bright zinc plated for rust resistance and the block
is anodised to increase the wear resistance of the threads
