1973–1974 · Aermacchi Harley-Davidson
The SR-100 is the Baja 100 with lights. Where the Baja was a pure off-road bike, the SR-100 could also go on the road.
History
The Baja 100 was a success off-road in America. For riders who also wanted to use the road, Aermacchi turned it into the SR-100. The biggest difference is the lighting. The front mudguard is also fixed to the lower yoke instead of between the fork legs.
A clever touch is the double rear sprocket: a small one for the road and a big one for off-road. Different tooth sizes were available. Only about a thousand were built, so it is a rare bike.
Buying
- Parts for these small Aermacchi two-strokes are scarce. Expect to search at specialists, at autojumbles and in Italy.
- Check that the bike is complete: covers, lamps and instruments are the hardest to find.
- Ask about compression and have it started cold. Smoke and rattles tell you a lot.
- Check that the lights and the switch are complete. That is where it differs from the Baja, and those are exactly the parts that are hard to find.
- Check whether the double rear sprocket is still fitted.
