The ezm q-matic is ratio is 2.5, drive sprocket I believe is 11T and
the rear sprocket is 72T, 26 inch rear wheel with a top speed of
about 32mph. Moves from a stand still with ease, accelerates
aggressively and smoothly, the most powerful combination I have with a
modded carb and 7/8 inch ID flexible exhaust. The q-matic
makes the bike feel like it has an automatic transmission, as
the drives slips until about 12mph.
