Which motorcycle manufacturer uses engines with a desmodromic valve design?
Harley-Davidson
Yamaha
Ducati
Honda
A desmodromic valve is a reciprocating engine poppet valve that is positively closed by a cam and leverage system, rather than by a more conventional spring. The main benefit of the desmodromic system is the prevention of valve float at high RPM. It has been applied to top-of-the-range production Ducati motorcycles since 1968.
