sort of like a desmodromic* overhead cam , Ducati Fans , the upward and downward motion is controlled so you dont have valve float at high rpm ..

While I'd have to look up the spelling I do know what fietsbob says.
I'll add that I find it easier to move the bike via my feet when using clipless pedals. But I suck at trials riding so... Andy.
