Hi mad hatter
Base bike is an 80 G/S, but with lots of special parts!
Forks and front wheel are off a 2004 KTM 450 exc, engine will have Siebenrock big bore kit and a Moorespeed 324 cam. Swing arm and drive shaft, rear wheel are also Moorespeed. Gearbox is from Mikeyboy with low first and high fifth plus kick start. Fuel tank is HPN.
Fairing and triple clamps are from Herbert Gletter. Most of the rest is standard BMW stuff.
