1973 · Aermacchi Harley-Davidson
The TX-125 was a light all-rounder for road and trail, with oil pump, five gears and indicators. It was built for only one year.
History
Harley-Davidson brought out the TX-125 in 1973 as a bike that could handle both road and trail. The two-stroke had an oil pump, so you no longer had to mix oil into the fuel. Under the engine was a steel skid plate, and at the rear a double sprocket for road or trail.
Because American regulations now required them, it had indicators. It was followed by the SX-125 and the SXT-125.
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 oil pump works and is correctly adjusted. A pump that delivers too little will cost you the piston.
- Has the oil pump been removed so it runs on premix? Ask what ratio is used.
- Check the indicators and the relay; the wiring is more complex than on the older models.
