Hagsta wrote:Mystery Solved - I was talking to the "Known Bike Fiddler" this morning who said the bikes originally came from Chris Noon in Townsville. KBF's fading memory says the forks and backing plate are AT1 or CT1 (pre DT) and the rim is early YZ. The extended cable retainer was made up to accept the longer lever which came from his secret supply of Yamaha "Bucket Road Racer" stock.
Aha. Thanks Hagsta. Small world. Chris Noon was an off-road riding buddy when I lived in Townsville back in the late 1980s and early 1990s. Fond memories of Chris riding smoothly down a rocky downhill mountainbike track up near Cairns on his KLR650, fitted with a TT600 front end. Another one was Chris riding in a Pony Express on a tiny MX bike (and doing pretty well) Can't remember if it was a 100 or a big-wheel 80 but he loved racing little off-road bikes.
I'll take a wager with KBF about the forks though. I'm familiar with AT and CT Yamaha forks and these are nothing like them. My money is on them being 1978/79 (pre leading axle) Yamaha small trailbike (DT125/175) forks. CTs and ATs had ghastly steel fork sliders with chromed seal retainers.
The (secret bucket racer parts) brake arm with the webbing milled out made me laugh as you have to be pretty serious about lightening a bike to do something like that. I remember that back at the time, KBF had been fiddling the shockies on a TLR Honda to make it easier to hop the rear (remember this is in 1988) which is just one reason why he deserves the KBF monniker.
