AHRMA Vintage Cup Returns: Formula 750 named featured class for the 2027 season.
(September 21, 2026, Knoxville, TN) The American Historic Racing Motorcycle Association (AHRMA) is proud to announce Formula 750 as the featured class for the 2027 Vintage Cup. The big four-strokes that remade American road racing — Honda Fours, BSA and Triumph Triples, Norton twins, Harley-Davidson XR750s, Ducati V-twins and their period works replicas — will take center stage at every AHRMA National road race next season.
Sponsored by Roadracingworld.com and NYC Norton (nycnorton.com), AHRMA’s 2027 Vintage Cup features Formula 750: fully GP-kitted four-stroke machines of up to four cylinders, manufactured as 600–750 cc and built prior to December 31, 1972, and like design. It is a second Vintage Cup turn for a class first featured in 2023.
“Formula 750 is the sound and silhouette of road racing’s big-bike revolution,” says Kenny Cummings of NYC Norton, Vintage Cup sponsor. “These are the bikes that came out of showrooms and factory race shops and changed everything from Daytona to the Isle of Man. Whether you’ve got a BSA/Triumph Triple or Twin, a CR750-based racer, a well-tuned Norton, BMW, an XR750, or Ducati V-twin, 2027 is the year to get it out of the shop and onto the grid. Formula 750 already proved it can fill a Vintage Cup paddock as we saw in 2023. Let’s do it again — louder.”
Typical AHRMA Formula 750 grids include BSA Rocket 3 and Triumph Trident works racers and replicas, Honda CR/RC750 kit machines, Harley-Davidson XR750s (iron and alloy), Norton John Player and FIM production racers, Ducati works V-twins, Laverda SFCs, BMW works bikes, MV 750 fours, Rickman and Seeley specials, Yamaha XS650s, and more.
“Formula 750 captures the moment American road racing became a worldwide prize,” said Leasha Overturf, AHRMA’s Road Race Director. “These machines were the proving ground for factories, tuners and riders who rewrote what a production-based racer could do. Showcasing them in the Vintage Cup honors that legacy and gives today’s racers and fans the chance to see — and hear — the 750s that defined an era.”
“AHRMA continues to do the sport a great service by running a series for people to ride historic race bikes on the track, where they can be seen and heard in action. Roadracing World is happy to be involved with the Vintage Cup program again in 2027. Now go out and have fun on old bikes!” said John Ulrich, Founder & Editor of Roadracing World.

Motorcycles eligible for AHRMA’s Formula 750 class include fully GP-kitted four-stroke machines of up to four cylinders, manufactured as 600–750 cc and built prior to December 31, 1972, and like design. A complete list and technical requirements appear in the AHRMA Handbook, Section regarding Formula 750 (www.ahrma.org/ahrma-handbook).
Technical journalist Kevin Cameron, whose full history of the class appeared in a recent issue of AHRMA MAG, traces Formula 750 to Dick Mann’s 1970 Daytona 200 win on a race-prepared Honda CB750 — the moment a new kind of big-bike racing arrived in America.
Honda’s 1969 CB750 Four, Britain’s 750 twins and triples, and Harley-Davidson’s coming XR750 collided with a booming U.S. market. Sales doubled from 1965 to 1970 and doubled again by 1974. At the AMA’s December 1968 Competition Congress, Triumph and Harley pushed the top class to a straight 750 cc for 1970. Daytona became the most important motorcycle race in the world. Europe followed with the Imola 200 and Paul Ricard 200.
The four-strokes that started it — Mann’s Honda, the BSA Triple that gave him a last British win in 1971, the iron XR750 that overheated at Daytona then became a dirt-track legend in alloy form, plus Norton, Ducati, Laverda and the works replicas — are the machines AHRMA Formula 750 still races. Vintage Cup 2027 is for the Fours, Triples, twins and V-twins built before the end of 1972.
Whether you have a Triple or a Four, a Norton twin or an XR750, a works replica or a production racer — bring it out for the 2027 Vintage Cup.
