Finally went out and exercised the checkbook and bought a new T120. After riding my 2007 T100 for a year the 120 is quite different in sound and power. The gear ratios are quite different, and the power curve is broader than the 100. The 270 degree crank setup makes for a very different sound. I still can't reconcile how a 270 degree crank would work, how it benefits the power and smoothness of the engine.
Lead mechanic at the dealership told me that the crank configuration allows better "tire recovery", meaning power pulses from the crank allows the tire to recover (?) during the pause in pulses as the crank rotates or some such. Never heard of tire recovery, and I kind of doubt that is the reason why Triumph designed this engine.
It's not as smooth as the 100 with the 180 degree crank. It's a great bike, the 120, and I know I'll enjoy it a lot, I do love having that 6th gear, but the crank configuration, anybody have a better explanation of why the heck that benefits?
