20 years ago, or more, I remember reading an article on a new engine that Triumph had the patent for. It was going to revivify the British M/C industry (ha!). Heard nothing of it since. Called the SPX (for Stepped Piston 2-stroke - maybe they couldn't spell "2"). I've tried searching the net for info on it, but all I get is crud about Novell's networking protocol. Anyone know anything about it?
