Doppler benefits from a long experience acquired in competition. Dopplers know-how allows us to obtain parts of excellent quality.
Developed in France, the Origin cast iron cylinder can be fitted to all vehicles equipped with a Minarelli AM6 engine.
Doppler has developed this cylinder for daily use, it is approved for road use (49/9).
It features a 3-light booster exhaust and a modified transfer (modified scavenging for reduced dead volume).
Dopplers knowledge has made it possible to increase the engines torque without altering its power at high rpm.
The tuning is simplified and the assembly is faster.

- 1 Cast iron cylinder 5 transfers Ø39.91 with boosters
- 1 Complete piston (pin + clips + 2 rings)
- 1 Aluminium bi-hemispherical cylinder head with removable stud
