Something different, it's British and well engineered. Sorry but it only shows the bike from the waistline, but it conveys the engineering of this bike. It was built by the Winwood brothers who worked in the aerospace industry. This actual bike was ridden by Ross Winwood in the 1970 SSDT. It has an aluminium plate frame, screwed/bolted together in places and a billet turned headstock. 175cc BSA Bantam power plant with aluminium billet triple clamps (yolks) and I think either MP or REH front forks.
D7 Frame with brace.
BSA C15 Yokes and Forks (they fit streight in).
Widened S-ARM or fit cub S-ARM, (they fit streight in).
Longer rear shocks.
Small tank & seat.
Sammy Miller Footrests & Chain tensioner.
D7 engine with d10 175cc barrel (different ports) crank stuffers disk type to up the crank case compression, easy to make & fit if you have the motor in bits.
Open up and polish all barrel ports, make sure not to go too much because of piston ring damage.
Skim the head to up the compression ratio (not too much for trials use).
Amal Concentric carb & longer induction neck.
Change sprockets for low gears, 12 tooth final drive sprocket and a 66 tooth rear sprocket.
For motorX they used to remove the flywheel & use a battery, up the compresion ratio (Todd head), Todd horse shoe crank stuffers, disc crank stuffers, piston stuffer, and the list goes on!
Todd was the Bantam tuning guru.
