BMW s1000rr homie. BUY IT
Definitely. If I was to go brand spanking new, that's what I would most probably go for. For the % difference in price, you may as well go for the BMW with the shed load of technology in comparison to the Honda which is about NZ$5000 less (all of a sudden - last year it was much closer before the BMW launch), btw US$ 0.70 = NZ$1.00 approx.
I'm in the same boat as you, but I'm looking for a street/track bike. Most of the stuff you said it what I've been reading around the net. The GSXR's I've sat on seem to be the most comfortable for me, I'm about 6'0, and it has allot of features, I think it's the happy medium in most categories.
That's what I have picked up on, comfortable and features such as 3 electronic map settings at the touch of a button.
I've sat on the R1 and I actually never find the Yamaha’s comfortable, they always seem to put you in an aggressive race position.
Heard that complaint a few times, but then again, it is supposed to be a race replica.
CBR's are lower on power, but very useful to most riders because of that.
I spoke to a 2008 GSXR owner this past weekend and apparently this is where the 3 ride settings are so useful. Apparently he had it set in "C" mode in the hills a while back and was still running away from the other bikes as the bike was easier to ride and actually more fun.
I like the 675 as well.
However if a liter bike is what you are after...
I would pick up the GSXR first.
Of the four, it always seems to be the one that comes out of the box the way you are trying to make the others work. There is tremendous aftermarket support and they can be had for cheap.
Well that is what I am picking up on, overall fit and finish isn't Honda quality, but apparently you are getting a lot of bike for your money relatively speaking. So basically bang for buck. Seems the 2007/8 is the pick of the GSXR's. From all accounts a very good bike and they are reasonably affordable, around the NZ$14K mark, so approx NZ$10K cheaper than the average new price for all 4 Jap brands.
Apparently the GSXR's are the heaviest of the bunch though. Will check on this, don't know how much difference this makes for street use realistically.
