October 31, 2005 Yamaha recently released the details on its 2006 R6 Supersport motorcycle. It has a fuel-injected 599cc four cylinder engine with four titanium valves per cylinder and revs cleanly to its 17,500 rpm redline, making maximum power of 133bhp at 14,500 rpm – that’s 221 bhp per litre – roughly the equivalent of a front-running MotoGP bike. It’s engine also has a slipper clutch as standard and it is the first production motorcycle with a ride-by-wire throttle. That’s right – there are still throttle cables but they run to a computer, not the carburettor slides.
