Body
The tank, radiator shrouds, seat, and rear fender are 2000+ Honda XR/CRF50 or chinese import/pit bike.

Engine
The engine can be any 1969 and up Honda mini trail-50 ,CT-70, SL-70, trail-90&110, xr50,crf50, or any of the chinese import pit bike 50 to 150cc horizontal ohc motors. Semi-auto or auto transmission is best - manuel clutch is difficult to use on a motoped because of no foot brake.

Front fork
The front fork should be a dual-crown fork with at least 7" travel. The head tube is 1 1/8 and is 5.5" long. The fork should have a tall crown and a steerer tube at least 8.5" long with standard stem or about 7.5" long with direct mount stem.

Brakes
Brakes are mountain bike - 51mm International Standard disc brake mounts. You should use at least an 8" rotor.

Hubs and Wheels
The rear hub is custom made and have to get from us. The rear hub is 48 hole, and the rear rim is 24". Halo and Arrow Racing make a 24" 48h rim. The front rim is standard 26" mtb

Cranks and bottom bracket
The bottom bracket is custom made, it's wider than a standard mountain bike. The cranks are mtb or bmx with square taper JIS interface.

Rear shock
The rear shock is a 10.5" - 11.0" eye to eye, 3" stroke pit bike shock. Spring rate is around 500 lb for a 175 lb rider.

Exhaust
The exhaust system is custom made by us. If you try to use a standard pit bike(xr50) exhaust system the muffler winds up hanging down about 8" below the seat, so you have to do some rebending of the pipe and then make your own muffler hanger. We highly recomend using our exhaust system, it's tucked tight to the frame and gets routed through the subframe with the muffler under the rear fender, a must when riding with shorts on.
