About this model
About the Hercules K 100
The Hercules K 100 is a small German classic motorcycle from the second half of the 1950s. It uses an air-cooled Sachs two-stroke of around 98cc and a three-speed gearbox. It is a simple, light machine from an era in which originality, engine and frame numbers and correct 6V electrics matter much more than a low odometer.
For a buyer, the quality of previous rebuild work is decisive. A K 100 complete with the correct tank, exhaust, carburettor and wiring is much more valuable than a beautifully painted assembled restoration. Test clutch, shifting and charging once warm. Model-specific parts require patience, so choose the most complete and documented example possible.

Before you buy
What to check before buying
- Check frame and engine numbers, type plate and correct K100 version before ordering parts or assigning year.
- Measure compression and inspect cylinder, piston, crank seals, carburettor and 1:50 premix for leaks and hot-start behaviour.
- Test three-speed gearbox, clutch, chain and sprockets under load; poor shifting can mean rebuild work.
- Check 6V ignition, charging, light switch and wiring for corrosion and incorrect modern wiring.
- Inspect frame, tank, wheels, drum brakes and exhaust for corrosion, cracks and incorrect restoration parts.
