New aluminum rear sprocket from Sprocket Specialist. The new sprocket was
required because I am using a C-90 rear hub, which takes a sprocket with a 428 pitch
chain, however the small honda motors use sprockets with a 420 pitch chain. I had to have
a custom sprocket made to fit the C-90 hub but with a 420 tooth pitch. I took measurements
of the, center hole, bolt hole size and bolt hole spacing (from center of a bolt hole to
the center of the bolt hole directly across from it). I called Sprocket Specialist, gave
them the measurements and told them I wanted it made with 40 teeth, with a 420 pitch, in
aluminum with lightening holes... I had the sprocket in my hands three days later.
Including shipping it was $77. This is the second time I have used this company, I have
been very satisfied both times. |
