Suzuki RM80
1978—2001

I have tried to tell the Suzuki RM 80 model history on this page as I know it. This page is still under construction. I would be grateful of any contributions — sales brochures, magazine ads, magazine articles, pictures, specs, facts, corrections etc. Please scan the material in JPEG format (large enough that all the details are visible) and send them to me. Please tell me the source and the publication date if possible. If you send me pictures of your own bike, please follow these instructions.

1978 Suzuki year code: C

The earliest types of the RM80 junior level moto-cross machine was an air-cooled two stroke producing a healthy 14.5hp @11 000 rpm when launched in 1978. Induction was both piston and reed valve, and although fast had a fairly fearsome power-band, not the best mix with a bike weighing just 62kg, likely to spit off the unwary novice straight out of the back door! By the early 1980’s the model acquired liquid cooling and more power, this time with a little more flexibility. Model evolved over the years, and was extremely popular with Junior riders, but was replaced in 2002 by the RM85. 1978 Suzuki RM80 retail price in Japan: 145,000 yen

Suzuki RM80 was evolving fast during its first years. The '79 (N) version of the RM80 had a new, slightly smaller, fuel tank with new graphics, chrome plated rear springs and silver/gray painted swingarm. The wheelbase was increased by 30 mm and the ground clearance was increased by 10 mm. Suzuki managed to squeeze out one more horsepower of the 79cc RM80 engine and maximum power output of the RM80 was increased almost every year until 1990, when Suzuki deceded that 27 hp was enough and no more upgrades were made to the engine before it was replaced with a 85cc and the RM80 became RM85 in 2002. The only color option for the early models of the RM80 was Phlolina Yellow (6LF). 1979 Suzuki RM80 retail price in Japan: 125,000 yen
