bike is a four stroke Honda with a custom built auto clutch, custom aluminum gas tank, exhaust, intake, electric start (my own design). My own design jack shaft and custom bottom bracket (details of which I need to keep to myself at this time). Single line drive train, three speed internal hub at the rear, Hydraulic front and rear disk brakes. 125mpg, top speed of 30mph (geared not to go faster, but it would easily), 75lbs with fuel (a pig for a bicycle, a feather amoung scooters). Thanks for your feedback.
