Typical AHRMA 350GP grids include wide variety motorcycles from Aermacchi, Bultaco, Honda, Ducati, Kawasaki, and Suzuki.

Motorcycles eligible for AHRMA’s 350GP class must have been built before December 31, 1968, or be based on a like design and may have up to a 350cc air-cooled four-stroke engine with overhead valves and cams; a 350cc air-cooled single-cylinder two-stroke; 250cc liquid-cooled, single-cylinder two-stroke; 250cc air-cooled twin-cylinder two-stroke. A list of eligible machines can be found in the AHRMA Handbook in Section 10.2.3 350 Grand Prix (www.ahrma.org/ahrma-handbook).
“The 350 GP class has been important since the beginning of road racing. Practically all the factories that competed in the 500 class also competed in the 350 class. Norton and Velocette dominated before WWII and the immediate post-war period. The 350 Junior class ran at the Isle of Man from 1911 to 1976, Norton winning 12 times, MV nine times and Velocette eight times,” said David Roper, a multi-time AHRMA champion and frequent 350GP competitor.
“When the World Championship was established in 1949, the 350 was one of the four solo classes and lasted through 1982. The championship was won by a four-stroke every year until 1974 when the two-strokes took over until the class was eliminated,” Roper said. “Some manufacturers enlarged their 250 to 350 (Moto Guzzi and Honda), some made smaller versions of their 500s (Gilera and MV), and for some the 350 was their prime size and they enlarged them to make forays into the 500 class (AJS and Velocette). Singles, twins, triples, fours, and six-cylinder motors were successful.”
