This is ltd #74. I bought the bike with no engine on it from ridney at treatland. I started with a e 50 pollini. I built my first za 50 for the bike. I got a new crank and new clutch pack of both gears from treatland which rock by the way. I totally believe in the new and improved clutch material on these cause I've put miles on these new clutches with both a Gila and metra kit. They still look good and are running strong. The bike has 21x35 gearing and has been gps'd at 64 mph.
