Board track racers vs today

79 Views 1 Reply 2 Participants Last post by  Unkle Krusty
From what I've read, board track bikes were small, light, had no gear box, no brakes, no kickstarter, and small engines.

They are claimed to go up to 100 mph, which means they are close to the top speed of my 650 Nighthawk.

Must be horsepower to weight ratio?

How did they stop with no brakes? perhaps cut the engine off, and let compression braking slow them down until they jumped off?

Less wind resistance. Horsepower improves acceleration. Less wind resistance improves top speed.
They also used fuel other than petrol to get extra power. About 90 is when the wind effect is most noticeable, but the drag starts at a lower speed. There was not need to stop. Engine drag and wind drag do the work.
