The Suzuki TM100 Jet Specifications

Throughout its company history, the Suzuki Motor Company has experimented with building bicycles with small engines. By 1953, the company won its first sponsored event with a 60-cubic-centimeter motorcycle at Mount Fuji Hill Climb. The next year, Suzuki applied their knowledge of motorcycle designs to the consumer market, manufacturing more than 6,000 units per month. The TM class of off-road motorcycles was advertised as a World Champion motocross machine, giving the appeal of a casual trail-ready bike and a competitive cycle.

  1. Performance

    • In 1974, the TM100 was introduced with a 98 cubic-centimeter, single-cylinder engine. The air-cooled motor was a two-stroke design that produced 14 horsepower at 10,000 rpm and 7.69 foot-pounds of torque at 8,000 rpm. The bore and stroke of the TM100 in 1974 was 1.97 inches by 1.97 inches, remaining consistent in configuration the following year of the bike's production as well. A five-speed manual transmission was fitted with the TM100, which featured a primary kickstart that allowed for restarting in any gear. The bike came with Pointless Electronic Ignition system and CCI automatic lube. A Mikuni VM-series carburetor was standard in TM100 bikes, designed as a round-slide, single type. The compression ratio was rated at 7.5-to-1.

    Wheel and Suspension

    • In 1974 and 1975, the Suzuki TM100 came from the factory with traditional spoke, aluminum-alloy rims. The wheelbase of this bike was 52.6 inches, the same as found in the TM125 motorcycle. The front tires were 21 inches by 3 inches, while the rear tires measured 18 inches by 3.5 inches. Stopping capabilities were handled by drum brakes on the front and rear wheels of the motorcycle. The tires were 4PR and full-knobby, giving the TM100 an aggressive stance and ability to tackle any terrain. The front suspension was handled by a dual front shock that allowed for 5.7 inches of travel. The rear suspension was 3-way adjustable, oil-dampened shock and allowed for 6.5 inches of travel.

    Body

    • While the engine used in the 1974 and 1975 TM100 models was the second smallest in the series, the frame and chassis was comparable to the off-road bikes with larger models. The overall dimensions of the TM100 measured a length of 79.1 inches, a width of 36.8 inches, and a height of 43.1 inches. Ground clearance of this bike was 7.1 inches, which was more than that largest TM400 motorcycle, but still slightly less than the TM125 and TM250. In 1974, this particular off-road cycle came painted with a yellow fuel tank, showcasing a wrap-around green/white sticker. The next year of its production, the fuel tank was all yellow with a Suzuki logo. The rest of the bike, including the engine, was black with white accents.
