1972 · Aermacchi Harley-Davidson
The Shortster was Harley-Davidson’s first minibike, built by Aermacchi in Varese. A small, light bike with mini wheels, meant for young riders and for the campsite or back garden, but with full lighting.
History
In the early seventies Harley-Davidson also wanted to reach the youngest riders, just like the Japanese makes with their minibikes. For that Aermacchi built the Shortster: the 65 cc engine of the Leggero in a tubular frame with a thick backbone and small 10-inch wheels.
The Shortster had hydraulic suspension front and rear, a speedometer, a braced handlebar, a dual seat, a high exhaust with heat shield and stainless-steel mudguards. It was sold under this name only in 1972. In 1973 its successor got a 90 cc engine and four gears: the X-90.
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.
- Many Shortsters were used hard by children. Check the frame, the fork and the little wheels.
- A striking colour of the period is Furious Yellow.
