Dopplers know-how allows us to obtain parts of excellent quality.
Developed in France, the Origin cast iron top end can be fitted to all vehicles equipped with a Minarelli AM6 engine.
Doppler has developed this engine for daily use, it is approved for road use (49/9).
It features a 3-light booster exhaust and modified transfers (modified scavenging for reduced dead volume).
Doppler 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.
