If I was in the market for a bike with that kind of power, I'd definitely get the StreetFighter before the MTS. Much better looks and handling, fits me better, yeah. I came pretty close to getting a 1098SF, and might still do it.This too is my answer. Just bought a new car to stave off the temptation of being a beta tester. 3 more years or so of car payments and then the V4 MTS. OMG the tech and power. Someone is going to to have to create a new forum section. It'll have all the same problems plus a few new ones as they roll out.
I'm sure focus groups and marketing people judged the street fighter to be the best non-sport platform for the V4, but joke's on them! More MTS people will clamor for the V4 and generally have more money to spend. Purely anecdotal. OK, just me, but there might be more of me...
OTOH, I've spent the last 26 years on M900 carby Monsters, with 75hp, and very rarely find myself not having enough power. With decent foresight and smooth riding, I find myself not getting left behind on the road until speeds well past what is reasonable in public. That's why I'm looking more to the 939SS; it's got a great balance of characteristics, and more than enough power and performance for real life.
I'm not ever going to be racing for anything real. I do trackdays now and then, and the M900 has been fine for that. If at some point I become inclined to get a faster bike for trackdays, I'll probably go with a 1098SF, or a good 998 -- either of those would be plenty of fun and well fast enough for the purpose.
