Top speed is not a goal for backroad development. The team was curious and we got some data, and we post it for others.
She ran 56 mph at 7800 RPM today WOT with the stock 15T Front and 46T rear. At 7000 RPM she will cruise at 50 mph.
More important the team is pleased that the stock final drive ratio of 3.07 appears to be satisfactory so far on a couple of backroad rides. If that is not enough, the team picked up a 50T rear sprocket and with that and some front sprocket changes we should be able come up with a ratio we like.
The Team members by consensus, requested I throw in some comparison info for all those Backroad riders that get elevated blood pressure when we start talking about final drive ratios above 3.00 because they know it corresponds to offroad capability. The WOT speed number generated by a final drive is also an easy measure of engine performance and torque which can be used to suggest performance in off-road terrain. I have run the HAWK over the same WOT course with a final ratio drive of 3.18, with an improved exhaust by way minus a CAT, more fuel through carburetion, 21- and 18-inch wheels, and the WOT equaled 58 mph. At 7000 rpm the HAWK turned 51-52 mph. The 200cc stands in with good company!
