Columbia 1937/ Zeda motorsports race bike

This motorized bicycle is purpose built for racing. I just took 6th place overall in my class at Apex raceway in perris, California this past weekend. I build these bikes from the ground up, including all engine work, welding/fabrication, assembly and testing. As well as racing. I built this bike to get me into the races only after my primary bike was totaled in a crash. I am selling this one to fund a new version of the bike I lost. I work hand in hand with some of the biggest names in the industry and I am known for my custom exhaust and gas tank work. Watch for Mason Machine Works at upcoming motorsports events! Some specs include; Zeda 80 bottom end(custom port matched by Robert Bianchi of {url removed}), mz Miami sleeved cylinder(fully ported and flow tested), windowed piston, Yamaha gt80 reed valve, dellorto 19mm roundslide carb, 6cc cnc cool head, one off expansion chamber exhaust, 10/36 gearing. Alex double wall heavy duty front wheel, cranbrook heavy duty rear wheel(10ga spokes), NOS Ritchie Moby Bite 2.1 tires, Rockbros mountain pedals, tektro hydraulic front brake, stream ride pleated springer seat. .85 gallon fuel tank. 55mph bike! Nothing like the motorized bikes you see all the time! Serious offers only. You can test ride this bike as long as my wallet can test ride your cash!!! No trades! No lowball offers(this isn't a 300-500 dollar motorized bicycle like most of what you see). Selling for a very reasonable price.
