What was the top speed of Suzuki RG 500 Gamma?

Answer 1

A stock RG500 square four Gamma Suzuki went 133 mph in a published road test, about the same as the early GSXR-750. With higher gearing and no airbox, a prepped one averaged a 500 class stock record of 151 mph at Bonneville, with a wind assisted one way speed of 161 mph.

At Daytona, a fully prepped RG500 GP bike ridden by Randy Mamola went 190 mph on the back straight (before the chicane was added to the track). By comparison, the same year Kenny Roberts had to skip the infield section of the track to maintain enough speed down the main straight to reach 190 on the back straight on the Yamaha GP bike.
