And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.
Worked really well, since works racers (think this is the 1950s Benelli)don't count cost! Very accurate valve timing with vernier adjustment giving over 100 bhp/litre.
Noisier (the gears whine), smooth power delivery because the timing is more accurate and maintenance on a works engine is of the (tear it down after every meeting type.
@ Robert The Biker: Wasn't there another geared bike like that? Not a pasta burner? My brother is a race builder and I remember something like that in the back of his shop. I thought it was a rice burner though. I could be wrong about that.--Ray
Desmodromic valves. Opened and closed by direct mechanical action, no springs involved, so no valve float at high rpm's, allowing really high redline. And adjustable valve timing.
The all gear drive eliminates the cam chain and tensioner.

ReplyDeleteIs it noisier or quieter? Smoother? Require more maintenance?

ReplyDeleteHad me fooled. The scale bothered me a bit but, I thought it was the first experimental heart pacemaker.

ReplyDeleteThey were quite common on Italian bikes, especially single cylinder ones. Benelli, Moto Guzzi, MV, Moto Morini, Ducati, all gear drive.
