Thought I would clear up some confusion on model designations on your 360 Enduro. This model motorcycle was sold at least through the 1971 model year (probably for several years after 1971, just can't remember for sure) and was designated the 360RT1. It was sold as a street legal "enduro" model. Other models in this same enduro series where AT1, 125cc, yellow tank: CT1, 175cc, green tank?; DT1, 250cc, gold tank; and RT1, 360cc, black tank. The big deal for desert riders of the time was to remove the lights and stock fenders, install GYT-R performance kits for the motor, a better exhaust
system, knobby rear tire and a K70 X 19 front tire. Then off to the desert with our 5-6 inches in the front and 3-4 inches in the rear state of the art suspension.
My first new motorcycle was a 1970 Yamaha
125 AT1 Enduro. I still have the owner's manual for this motorcycle. In 1972, Yamaha
came out with their first true motorcross motorcycles. They were the Yamaha 250DT2MX and the 360RT2MX. They were HOT!! The colors for both motorcycles were silver, black, and red. The only differance was in the arrangement of the colors on the tank and fenders. My second new motorcycle was a 1972 Yamaha 250DT2MX. All of these motorcycles were easy to work on, especially compared to today's motorcycles. The shifting forks bent really easy because the lugs on the transmission gears rounded off quickly with use. You had the opportunity to learn how to split the cases, if you owned one for very long and didn't want to pay a dealer for labor to work on your motorcycle. They also had an automatic engine oiling system on both the RT1 and RT2 series. It was common to not use it and instead, use pre-mix gas just to be certain that the engine was receiving lubrication. Brings back great memories of the wide open Southern California desert in the early 1970's (Ocotillo Wells, Poleline Road, and San Felipe Wash) just thinking about those old motorcycles.
