The Suzuki ACC 100 is a rare model from the A series of commuter motorcycles produced by this Japanese company in the late 1960’s and into the 70’s. As the name suggests, this motorcycle was an offshoot of the popular A 100 model, which sold well on the world market. Drivers liked the A 100 for its simplicity, ease of use and low fuel thirst. With the ACC 100 they also got a little more power.
Both bikes shared the same 98cc engine, a proven single-cylinder two-stroke engine. Suzuki retained its automatic oil pump CCI system for lubrication, a welcome feature in an early 1970’s Japanese motorcycle. The rotary valve engine of the Suzuki A 100 made around 9.3 hp at 7500 rpm. On a long distance he can accelerate the bike up to 100 km/h. In the ACC 100, Suzuki engineers tweaked the engine to elicit 10 horsepower at 8000 rpm. Since the bike’s curb weight remained the same at 83 kg, the ACC 100 was able to break the ton mark with top speeds of 110 mph. For a Japanese 100cc factory spec bike from the 1970’s that was quite an achievement!
There were a few other structural changes. The Suzuki ACC 100 received a new, upswept exhaust, as well as unique tank designs and body colors. Gasoline capacity stayed at 7 liters, making the Suzuki ACC 100 a good city or town bike with very short legs. The A 100 wore 2.50 x 18 tires on both wheels, which were sufficient for easy road driving. On the ACC 100, Suzuki kept the same front tire but introduced a wider 2.75×18 rubber for the rear. This gave the stronger wheel better traction. Curiously, the ACC 100 didn’t come standard with dual disc brakes. As with the A 100, twin drum brakes tried to do their best. Most owners have added at least one front disc for a safer driving experience.
The Suzuki ACC 100 was only produced between 1970 and 72 and is a fairly rare classic Japanese motorcycle. There are few surviving bikes, and even fewer in running condition. However, demand from collectors keeps prices respectable, especially if the bike has been treated well. As with other Suzuki A models, good quality parts are available, many of which are interchangeable. With the right kit, a restored Suzuki ACC 100 can still turn heads with its ’70s styling and surprising performance.
