FRONT SUSPENSION: original HONDA, rebuild with new tubes and springs.

REAR SUSPENSION: custom-built by WORKS PERFORMANCE gas shocks, 13.5″-long, Dual-Rate Springs.  (The question about correcting the length of the kickstand when custom suspension is installed comes up a lot, so, in anticipation that it would come up here again, the answer is yes.  The kickstand was lengthened by 1″. It was then polished and chromed.)

3-POSITION REARSET BRACKET: in-house design, allows 3 different positions for the rearsets depending on rider’s size and riding style preference.  CNC-machined from 6061 aluminum. The brackets are approximately 12″ x 5″ x 2″ overall (roughly 300 x 120 x 50 mm). There are two curvatures which offset the mounting points by about 1/2″ (12 mm) and the three circular foot peg positions are themselves some 3/4″ (20 mm thick) allowing the brake pedal and clutch lever to clear the exhaust pipes.  It took a big chunk of aluminum to CNC-machine these.
