My Tuono cost more in tyres than petrol. Don't get a v twin if you want lots of miles from a back tyre...
It also revved to 11k redline so quite high, but had balancer shafts so no vibration at all (had a go on a KTM Duke a while back and that felt a whole lot more vibey than any chainsaw I've ever used!). I'm unlikely to go back to an i4 (had an FZR1000 about 5 years back) but each to their own, all bikes are ferkin' superb in my book! If I had 2 choices, a 125cc commuter or nothing at all I'd fall in love with the 125!
