Runaway Urban Assault

Added: • Updated:


NEWLY UPDATED SPRING 2016 After a disappointing failure to get the bike ready for the Dirtquake USA event last summer, the Runaway has been in hiding, hibernation, and finally training/tuning for a big comeback this season. An MHR Replica 50cc cylinder proved finicky and self destructed shortly after showing promising initial results, and was replaced by a larger liquid cooled cylinder with something like a 46mm piston. I selected the 70cc Speedfight from the dropdown menu as it appears to be the closest match. A Stage 6 clutch from SIP Performance finally brought the requisite stall needed to matters out back, enabling spirited launches that are still controllable. Overall drivetrain balance and engagement is getting really good now with 15g +/- a gram or two up front (DR Sliders always) and the red contra spring working very well with the new clutch. Later this summer we'll put it on a Dyno and see what kind of numbers we can produce. Anyway, thanks as always to the talented and kind Michael Nazaroff for helping me make this bike the funnest money pit I own.

Will Childs: Saw this bike at the spring uphill battle rally 2013. Super sweet ride. Looks fun to ride and super comfortable. Those front forks are so beefy. Nice work!!!

WillD: I like comparing this and Mark Tway's David Choppafeild. You took the chopped version and made it an enduro, he took the enduro version and made it a chopper. And both turned out much for the better

Nash Wiley: best urban EVER!

Theodore Rael: this is an inspiration for me. thanks!

Christopher Hoke: most urbane urban
