If you were paying attention to American roadracing in the 1990s (more and more resembling a golden era), the name Martin Adams might ring a bell. Martin begat the Commonwealth Racing team, which in 1989 won its first AMA title: That would be the AMA Pro Twins GP championship (at the last corner, at the last round of the Series (Topeka), with Randy Renfrow in the saddle of the Commonwealth Honda RS850).

“The twin contained a C.R. Axtell cam, increased inlet length (torque) with two late-model Amal concentric carbs (38mm, I think). Total loss ignition. A five-speed Quaife …read more
