Bought as a commuter (have an FZ1 and an R32 Golf and needed something less thirsty...). This thing is great fun and, door to desk, is faster than both of my other transport options over a 5 mile journey through traffic.
Superb balance and handling, great finish, plenty of storage space and importantly for people who also ride 'real' bikes, this 2010 version actually looks cool.
Still running-in but, for a 250, I was expecting a bit more power. I expect that once I can 'pin-it', I'll replace the standard can (Devil do a pretty good one) with something that'll at least make it sound less like a sewing machine and may add a tad more ooomph.
Buy one - they're hilarious!
