Chain Sprocked BMW R 2, 3, 4






The dynamo was assembled together with a new wiring harness.

It all took about 4 hours.

Is simple and is installed without changes to the original circuit diagram.

The dynamo generates power even when it is kicking, the indicator lamp goes out immediately. 

The motorcycle almost has to go out so that the control lamp begins to flicker.

The dynamo simply works great in both lower and upper speeds!

We tested the dynamo with a small 3.2Ah battery without any problems.

Is really a great alternator that we can only recommend to everyone.

Just like all of our alternators in 12V and 6V that we offer.

Processing is really at a very high level.


All our Dynamos B are protected with polymer bimetallic fuses!

The electronics are thus 100% secured for inexpert Installation.

E. controller destruction is impossible.

We have designed our new controller so that you can drive without light.

The alternators build with the new regulator as much tension as it is needed.

There is no excess energy built up.

Smart controller !!!
