Nice!!

"Moved the rotating camshaft towards the center of bike..."

I hope he meant crankshaft, or he's just full of b@#^!$

Good article. Lot's of interesting info on the development of the bike.

Really? The crankshaft was not relocated by changing the cylinder inclination. The camshafts were, though, and toward the center of the bike. But I always have agreed that any concern over the gyroscopic effect of the camshaft(s) is vastly over-blown, as they are too light, too small in diameter, and spin too slowly to have a significant effect in that regard.

That's what I meant. :busted: If the crankshaft would have been moved backwards by a couple of cm, of course not in the engine, but relative to the frame, that would have maybe some (little?) effect.

Since the crank weighs more, moving it any distance would have a greater effect than moving the head, but the head is weight, too, so it does matter that it was shifted rearward. The only part that too big a deal was made of was the gyro effect of the cams.
