Started as a red 1979 Motobecane 50V. Modified the entire frame. Doppler 50cc ported. Doppler Head. AV10 Cases, HPI mini rotor, Doppler intake, Doppler boost bottle just added for fun and throttle response. Malossi MVR fairings thanks to Benji! Painted the frame and fairings all white. Trailtech Vapor, EBR forks, custom disc brake setup in front with Grimeca wheels, just added Sava slicks this winter. Raced it at MopedGP 2015, and at Totfest 2015. This is the "final" build after 4 years of remaking it. May go H20 in the future, but for now just minor tweaks.

Unsure on top speed, should be doing a run soon. Hoping for 60+, as it used to do 58. I am still dialing in the new clutch and HPI.
