They felt the original bike was a combination of heavy and underpowered, which made it somewhat less than desirable. So they chucked, well, almost all of it. The engine was torn down and put back together using only Harley's best bits, so it now has a nice, even 100 hp. They took so much off of the bike that it's now a full hundred pounds lighter, too. In short, Hardley can scoot.
