Custom built in 2005: hardtail frame, 3rd gen 100 cu in Rev Tech engine, 5-speed Rev Tech transmission, 2" old school Ultima primary belt drive and chain final drive. 21" front and 18" x 250 mm rear tire. I have jockey shift parts but am currently set up for typical hydraulic hand clutch / foot shift. Starts and runs very well. Paint is a little rough. I would only recommend this bike to someone that knows how to turn a wrench and loves the old school look, sound, and feel. Minimal electrical, as in ignition, headlight, brake light, and only rear turn signals.
