V4 power is usually a more progressive delivery than a peaky in-line 4 although cross plane crank in-line 4's will give a less harsh power delivery, the Honda isn't short of bhp to start with and should be a proper tool for getting on the gas early and smoothly to get that crucial exit speed onto the high speed runs, the only thing I'd add from my spannering / riding experience is that a bike new to the circuit may have a whole load of testing behind it but nothing at all can replicate the absolute beasting the whole machine will get while out on the TT Course, Clive and Bruce have so much riding / preparation experience between themselves though so I'm sure it will be a very well thought out racing experience for all of us.
