From a press release issued by AHRMA:

Triumph and AHRMA post Thruxton Cup Challenge points fund

Now there’s even more of an incentive to get involved in the Triumph Thruxton Cup Challenge – a $4,500 points fund posted by Triumph Motorcycles (America) Ltd. and the American Historic Racing Motorcycle Association.

The Thruxton Cup Challenge is a spec class featuring the new Triumph Thruxton 900 and running at all AHRMA Progressive Suspension Historic Cup Series roadraces during 2005, beginning with the Bike Week warmup race on March 3 at Carolina Motorsports Park in Kershaw, South Carolina, followed by the March 7-8 AHRMA Classics Days at Daytona International Speedway.

The series points fund comes in addition to an $800 rebate paid directly by Triumph to AHRMA-licensed racers who purchase a Thruxton for use in the 19-round national series.

AHRMA also has released the technical requirements for machines participating in the Thruxton Cup Challenge. To keep the series competitive and affordable, as well as to preserve the unique cafe-racer look of the Thruxton 900, few modifications will be allowed. Fenders, bodywork and wheels must remain standard, and treaded tires are required. The only modification allowed to the engine is multi-angle or radius valve jobs, but the exhaust system and jetting may be changed.

A complete list of technical requirements and other details about the series can be found by clicking the Thruxton Cup Challenge link at www.ahrma.org. Information on Triumph motorcycles is available at www.triumphmotorcycles.com.

AHRMA reports quite a bit of interest in the new series, with inquiries fielded from a number of individuals, race teams and motorcycle shops preparing entries. Included in that is an effort by Triumph that will see celebrity riders and journalists competing on a pair of “factory” machines.
