It seems like it could be very inexpensive. If you've already got a 450cc motocross of any brand you could just pop in a new front end, some road wheels, rear sets and a new lower travel rear shock. That's basically it. If you get them from the scrapjard cheaper still! Converting one for the b roads is a temptation too! Remember you'll be into the 130kg zone with this. 60bhp is all you need to eat 600's in the twistees and that's were the fun's at
