The History of the Suzuki ACC 100 Motorcycle

Lyle Ellerbee

The Suzuki ACC 100 is rare model from the A-series of commuter motorcycles manufactured by this Japanese company in the late 1960s and during the 70s. As the name suggests, this motorcycle was an offshoot of the popular A 100 model, which was selling well in the global market. Riders liked the A 100 for its simplicity, easy of operation and low thirst for petrol. With the ACC 100, they also got a little bit more power.

Both motorcycles shared the same 98cc engine, a tried and tested single-cylinder, two-stroke engine. Suzuki retained their 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 produced around 9.3 hp at 7500 rpm. On a long stretch of road, it could take the bike up to 100 kmph. In the ACC 100, Suzuki engineers tweaked the engine to coax out 10 hp at 8000 rpm. Since the kerb weight of the bike remained the same at 83 kgs, the ACC 100 was able to cross the ton mark, reporting top speeds of 110 mph. For a factory spec 100cc Japanese motorcycle of the 1970s, this was pretty good performance!

There were a few other structural modifications. The Suzuki ACC 100 got a new, up swept exhaust, along with unique tank designs and body colour schemes. Petrol 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 enough for basic street riding. On the ACC 100, Suzuki kept the same front tyre but introduced wider 2.75 x 18 rubber for the rear wheel. This provided the more powerful bike with better traction. Strangely, the ACC 100 did not come with dual disc brakes as factory standard. Like in the A 100, dual drum brakes tried to do their best. Most owners added at least a front disc for a safer riding experience.

Manufactured only between 1970 and 72, the Suzuki ACC 100 is a pretty rare classic Japanese motorcycle. There are few surviving bikes and even fewer in riding condition. However, demand from collectors keeps prices respectable, especially if the bike has been treated well. Like other Suzuki A models, good quality spare parts are still available, with many being interchangeable. With the right kit, a restored Suzuki ACC 100 can still turn heads with its 70s styling and surprising performance.
