Puch Maxi E50 - mid 80's model

Shown below is a mid 80's Puch Maxi E50. This particular bike is 100 % original bar the fitment of a Torqsoft design exhaust system.

The design brief for this pipe was to obtain the same top speed as the std pipe - 50 km/hr - but to have better hill climbing ability, particularly on the steeper hills. The hill climbing velocity for the steep test hill increased from 16 mph(25 km/h) for the std pipe to 22 mph(35 km/h) with the new Torqsoft pipe.
