ROVER Motorcycles

The 4 hp model replaces the 3 1/2 hp machine. Displacement and bore remain the same, equipment changes in parts.

Otherwise, it is known that the sound attenuation of the sports model was improved "due to increased police activities".

In today's offers, the terms "4 hp" and "3 1/2 hp" are sometimes wildly confused. So it may also be possible that confusion took place on this website. We are grateful for hints.
