1971 YAMAHA RT1MX 360: GYT KIT INCLUDED
Inspired by the success of the DT1 and AT1 a year earlier, Yamaha pulled out all the stops to release the beautiful black 360cc RT1 to the public in early
1970. Rumors had been circulating since the DT1’s
release that an Open-classer was in the works, and the
big Yamaha was almost everything the fans expected.
Our 1971 example is finished in gorgeous black with
red pinstripes. The 1970 RT1 was nearly identical but
BY TOM WHITE
featured yellow pinstriping. As with the other Yamaha dirt
bikes of the period, there was a street-equipped Enduro model
and a GYT-kitted all-out motocrosser. The RT1 had the same
frame and running gear as the DT1 Enduro, and the only con-
cessions for motocross were stripping off the lights, the 21-inch
front wheel and a high front fender. The most attractive thing
about the RT1MX was the $995 price—and the included front
number plate sealed the deal for first-time Open bike riders.
