Yamaha earned themselves a lot of fans with the release of the 360cc RT1 enduro in 1970. The motorcycling public had high expectations after the smaller DT1/AT1 models, so the big brother was going to be just as good, right? Indeed it was. It was available as an enduro and a MXer – this custom street tracker started as the former.
The enduro had 30 horsepower (the MX bike had 6 more) from the 360cc 2-stroke that featured Yamaha’s Autolube oil injection system. Gas was fed via a Mikuni VM32 carb. For more on the RT1 enduro, check out this trip down memory lane by Joe Gresh at Motorcyclist.
This example started with drum brakes and “a mild state of engine tuning“. The motor was rebuilt with Boyesen reeds and a new clutch, and the carb has been rebuilt as well. The custom bodywork is two pieces, the stock wheels have been replaced with lighter aluminum units, and the front forks are from a Honda CB450 (with a disc brake). The Autolube system has been removed so you have to run on premix, but I’m sure the seller has had lots of fun on it as he uses it “as a cool pit bike at vintage motorcycle events.”
