Built around Suzuki's cross - motocross motorcycle platform, the 1979 Suzuki RM 80 relies on a 79 cc (4.8 cu in) air-cooled single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 14.5 HP (10.6 kW) at 11,000 rpm. With a specific output of 183.5 HP per liter, the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the RM 80 measures 61.7 kg (136 lbs) dry, translating to a power-to-weight ratio of 0.24 HP/kg (4.26 kg per horsepower). Rider ergonomics and chassis geometry center around a 719 mm (28.3 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,171 mm (46.1 in) wheelbase engineered for quick, flickable steering geometry.

Notes
This is all the information that I have been able to accumulate over the period of about one year. Any additional spec sheet information would be appreciated.
Use this page to compare this motorcycle by its real specifications, not only by model name. Focus on the details that affect fit, comfort, handling, range and ownership.
Power
Compare engine output with similar motorcycles if acceleration, highway use or two-up riding matters.
Seat Height
Check the seat height against your inseam and riding posture before choosing a motorcycle.
Weight
Compare weight carefully because it affects low-speed handling, parking and confidence.
Brakes
Brake setup is worth comparing if you ride in traffic, mountains or with a passenger.
Suspension
Suspension details can matter for comfort, road feel and long-distance riding.
