Okay, my .02. I have a Speed Triple and love it like a rock but I wouldn't love it so much if it were my only bike. The 955i triple motor is a torque-monster and sounds like nothing on the road. Thay're very reliable, handle well (especially with Ohlins) and the brakes are real retina-stretchers. It also has the biggest :eek factor when people see it, or maybe it's more of a :bigbarf factor, especially in Roulette Green. But as an only bike, it's probably not as comfortable for long hauls as the others. I'm a little over 6'4" with a 36" inseam and can only do maybe 100 miles before I have to get off the bike for a half hour or so. Also, mine has a solo seat cowl which makes carrying anything other than a tank bag just about impossible.
All that said, it's also the bike that I daydream about rippin' on when I'm having a lousy day at work. It also passes the Starbucks test (ride for a couple hours, stop for coffee and stare at your bike for an hour) with flying colo(u)rs!
So I can't imagine not having one, but I can't imagine having one as my only bike.
Hope this helps!
