Mike Murphy's Rokon "Cobra"

.

Via the amazing site : www.vmxtv.com

Mike had this bike in boxes for years and no time to restore. So this year he didn't ride the AHRMA Cross Country Series and took the time to build it. This " COBRA " model is 1 of only 70 made. Super porting and a 44mm Mikuni carb. He rode it down the lane and it just digs a trench. Sweet !!

Rokon Motorcycles

.

Rokon is a Rochester, New Hampshire-based motorcycle manufacturer that builds unusual 2-wheel-drive off-road motorcycles which are sometimes referred to as Moto-tractors.
Rokon motorcycles use a combination of belt, chain, and shaft drives coupled to gear boxes to drive both the front and rear wheels. Older machines were powered by a West Bend (US Motor/Chrysler Marine) 820 2-stroke engine (134cc), while newer machines have either a Honda or Kohler engine of about 6hp. The wheels were able to hold gasoline or water for long distance trips.

These are slow-speed off-road motorcycles designed for use in the most rugged terrain. Some are capable of 35mph or more, but typical top speed is about 20 mph. Current models are the Trail-Breaker, Ranger and Scout. However, going up very steep hills the bike may only travel at 0.5 mph.
