From a press release:

With the demise of the Skorpion Cup contingency class in 2002, the American Historic Racing Motorcycle Association has created a new class for the MuZ Skorpion machines that have run with AHRMA for the past five years, as well as other production-based four-stroke singles such as the BMW F650, KTM Duke and Buell Blast.

The new Production Singles class is open to any four-stroke single-cylinder motorcycle available for sale to the general public and intended for street use in the U.S. and Canada. The machines must meet AHRMA’s SuperStock standard, which stipulates:

. No engine or chassis modifications.

. Stock wheels and forks. Fork springs may be changed. Modern DOT race tires must be used.

. The original carburetor and airbox must be used. Jetting changes are allowed.

. Allowable changes include brake master cylinder, brake lines, pads, rotors, shocks, handlebars, control cables, fuel and oil lines, exhaust system, and chain and sprockets.

. Replacement fairings and bodywork must be a cosmetic duplicate of the original and made of fiberglass or plastic (no carbon fiber).

The Production Singles class will debut at AHRMA’s 2002 Florida Bike Week events, March 1, at the DeLand Airport, and March 4-5 at Daytona International Speedway. For information, call 615-851-3674, 913-268-4401 or visit www.ahrma.org.
