Once you mentally adjust to the torque the Rocket makes, no bike will ever feel the same again. I've tried describing to others why nothing else truly interests me anymore, but always come up lost for words.
The carpenter power is totally tractable, and accessible as long as your pointed in a safe direction with sufficient space to distort reality. Docile as could be when cruising, very very easy to modulate power, you get a throttle reaction directly proportional to the amount you open it, as it should be, instead of "a whole bunch of power by 70% and then not much of a difference between 70 and 100" as is found on nearly every car, and to some degree the stock R3.
The fact the R3 comes with 56mm TBs is clear evidence Triumph never originally intended for the bike to only make 120hp/150lbft at the wheel, those power levels could have been achieved with much smaller TBs which would have fit the stock power level better.
Coincidentally, the new superduke R also comes with 56mm TBs, and makes a lot more power per liter than the stock R3. Infact, 150whp/95lbft * (1.33)*(1.17) (to account for the missing cylinder and displacement) = ~235hp, probably right around where Triumph originally intended the power level to be, and, coincidentally (or not depending who you ask), just a little under what a 265kit bike on pump gas makes.
