Two German engineers. Two 50cc two-strokes. One and a half years riding the Australian Outback.
Bea & Helmut from Time to Ride on tackling remote tracks, living at 50cc, and the unexpected effect those little bikes had on the people they met.
Strong, fun conversation.

A prototype two-stroke internal combustion engine that uses a rotary exhaust valve eliminates the need for oil mixed with fuel, resulting in cleaner and more efficient combustion. It can therefore be run using natural gas, hydrogen, and biodiesel as well as gas.
The defining characteristic of a two-stroke engine is to fire (combust) every time the piston is at top dead center. This makes them highly power dense, but also notoriously makes two-stroke engines dirty, inefficient, and not prone to long lifespans.
This is a glorious article about this fantastic motorcycle

This is the greatest two-stroke motorcycle of all time in my humble opinion IMHO
In 1979 this model was king
Four stroke motorcycles are meh in comparison
