I will tell you one thing, GMA brakes stop. I have never had a Sportster with such great brakes, and I include my 1996 XL-1200 Sport in that assessment. In addition to the GMA brakes they are famous for, Bill machined billet wheels for the bike. He also whipped out some billet headlamp mounts and a billet license plate bracket. He also got an aluminum JMA rear swing-arm before the went bankrupt and screwed all their customers.
The bike has a Stortz aluminum tank and fiberglass fenders. I believe the inverted front forks are Stortz items as well. I assume Stortz made the triple tree and clamp. One day I will haul this up with my load cell shackle and find out what it weighs.
The engine is stock, which is just the way I like it. The exhausts are aluminized, and the heat shields are chromed. It has the base Del-Orto's, not the execrable old flat-slide Mikuni's that wear and don't come back to idle. Other than the kill-me rear brake torque rod, all I want to change is the clutch cable for a braided one that resists the exhaust heat better. The factory cable got melted since the bike does not have the cable routing bracket installed.
