Afternoon chaps..first off thanks to Matt for posting the pic of my (very) shiny new bike with my son behind it. Just got back from my second outing on said mosheen, absolutely love it, done approximately 300 miles on it now, cracking little bike. In answer to your question Matt, yes mate it does sound as good as it looks. Mega throaty n raspy indeed, plus it's mega lightweight, unfortunately it doesn't come with the get out of jail free card, although I have ridden past about 4 parked up police cars now and non of them av pulled me in over it. I think because it doesn't have the pitch of a four cylinder bike it doesn't seem quite as offensive. I would recommend the 390 to anyone, cracking bike.
Cheers, Michael
