From a press release:

Team Obsolete is pleased to announce its 2002 Daytona Vintage lineup, by special arrangement with Daytona International Speedway. Isle of Man TT winner Dave Roper and “Superfrog” Yvon Duhamel return, aiming for victories in the 500 Premier and Formula 750 classes respectively.

David Roper will be riding an ex-Al Gunther tuned, Dick Mann framed Matchless G-50. Secrecy surrounding the specifications of this ultra rare, non replica motor in the Team Obsolete labs is at an all time high.

Yvon Duhamel, patriarch of the racing Duhamel family will ride the ex-Dick Mann BSA A75R that won the 1971 Daytona 200. During the decade that Yvon has been racing this legendary machine at Daytona, he has had one win and several second places.

Roper and Duhamel will be joined by Jerry Liggett and Dr. Lon McCroskey on “Beezumph 750 Triples”, plus multi-time Daytona winner Erik Green, and Tupper Robinson, both on AJS 7R “Boy Racers.”

The legendary AJS PORCUPINE will be on display at the Team Obsolete pits.

Team Obsolete is sponsored by Vanson Leathers, National Motorcycle Museum (UK), Avon Tyres, Works Performance Suspension, Bell Helmets, Air Tech, R/D Springs, and Agusta Aerospace.
