The Sixstroke Engine has extraordinary qualities. Capable of producing substantial torque at low RPM or peak power far greater than an equivalent poppet valved four-stroke, the development of Malcolme Beare's Sixstroke Engine is back on track.
The R12 Type 212/1 of 1935 to 1938 had hydraulically damped telescopic
Leading link forks as fitted to the R60/2 and several other models
of the 50's and 60's.
