If I didn't already own a 2010, I would definitely be in the market for the HP4,
but I bought mine WITHOUT all the bells and whistles cause I wanted a
simple machine, though I would probably have gotten the ABS & Traction Control if I had to do it again. I do have the shift assist, but most
of the time I just love to shift it using the clutch and can do it almost as
fast as using the shift assist.
Having "customized" my bike to the way I like it, with some carbon and tinted
windshield, (have yet to install the Yoshimura tail tidy), and having test
ridden both the 2011 and 2012, I don't find the HP4 all that exciting since the
engine is still basically the same and if you're only a street rider like me, I
just don't see all that much in the HP4 to trade mine in. I just love my 2010 and IMHO I think that it is nicer looking than the HP4 and am still a long way from riding it to the max of its potential the way some of the stunt riders do.
Just my $0.02 worth.
