Just got back from Castella vinduro and I must say the 390 continues to impress me no end. It lugged my fat arse around for a total of 8 laps(the most by anyone) and you can't embarass that engine. Super easy to ride, pulls from nothing and rips when you want it to. I want it in my modern bike. I have to get a go on a 430 if they're better than the 390. Have I mentioned I love my 'varna?
Cheers,
K
