It isn't finished enough for me as I would put fenders on it and some sort of tail section after the seat, but, all in all it is a pretty nice job on an 80's sport bike. I endurance raced one back in the late 80's and while it was not as good as the CBR Honda it was easier to go fast on. We won our class, 600 production, at the 24 hour of Nelson Ledges and finished 9th overall. Not bad for a POS Katana. I think this would be a great everyday rider.
