Desmodromic valves are those which are positively closed by a cam and leverage system, rather than relying on the more conventional valve springs.

For those that would like more information on what this is/how it works/early&late theory etc., Click Here (http://en.wikipedia.org/wiki/Desmodromic_valve)

Also, thank Mikerex for bringing this up at lunch one day. It is a very interesting design.

thats pretty cool. i wonder if makes more horsepower over the valve spring. to me it seems like it would make more but looks like it might wear down the cam lobes faster. i dunno. i like my suzuki.

Although this technology isn't new, I found it to be very interesting. I'm mean, you can't float the valves. LOL How bad ass is that?
