That would be "Historic Production Heavyweight" I guess. This is from
the AHRMA:

Historic Production is open to production street machines built up to
December 31, 1972, and like design. Machines must use the standard
production OEM frame, swingarm, forks and handlebar mounts. Engines must
be original OEM bore and stroke regardless of displacement (plus
allowable overbore, as described in rule 9.7). Classes are Lightweight
(four-strokes up to 500cc, 250cc two-strokes and certain 350cc
two-strokes) and Heavyweight (four-strokes up to 750cc and 350-500cc
two-strokes).

10.6.1 RIDER ELIGIBILITY: This class is intended for novice and
non-professional veterans.

10.6.3 Among the eligible Historic Production Heavyweight motorcycles
are: BMWR75/5

BSA, all 650 and 750 two- or three-cylinder

Ducati 750 round-case Sport or GT(NO DESMOS)

Honda 750 four-cylinder

Honda 500T two-cylinder

Kawasaki 500 two-stroke

Laverda SF750 (SFCmust compete in Formula 750)

Moto Guzzi 750 (V7 Sport must compete in Formula 750 or Sportsman
750)
Norton, all 650/750 (except short stroke)

Suzuki 500 two-stroke

Triumph, all 650/750 two-valve head, two- or three-cylinder

Yamaha RD series 350/400 two-stroke

Any other classes available?

Would Mr. Pitts care to comment on the likely success of any of these
machines?
