Why do speedway bikes run on methanol?
The fuel used to power a speedway bike is pure methanol this allows an increased compression ratio to the engine which then can produce more power than other fuels therefore giving increased results including higher speeds.
What fuel do they use in speedway?
With a top speed of around 80mph, speedway bikes have no brakes, just one fixed gear, a clutch and 500cc engines which run on methanol fuel. In power to weight ratio, a speedway bike can accelerate from 0-60 mph, faster than a Formula 1 car.
What engines do modern speedway bikes use?
Speedway bikes use a methanol fuelled 500cc engines which produce around 85 BHP. The major manufacturers are Jawa of the Czech Republic and GM of Italy. Modern bikes must adhere to strict weight limits, and use a ‘lay down’ configuration that helps produce a low centre of gravity.

What does a speedway bike cost?
A current speedway machine can cost from $7500 upward, and the ever-increasing power levels extracted from the 70+-horsepower, machines require careful maintenance to avoid reducing an engine that can have that much again in performance work into a worthless lump of alloy.
How do you start a speedway bike?
Woffinden says: “You start by leaning off the bike to tip it sideways and turning the bars to the left. You’ve got your left foot down on the steel shoe and because there’s some weight off the bike it’s freer underneath you. Then you roll off the throttle and nail it again to get the wheelspin that makes the bike turn.
Are all speedway bikes the same?
Anatomy of a speedway bike
Speedway bikes are completely unique, they are 500cc, have a single fixed gear and no brakes! Bikes are differentiated by the engines used, the rear wheel sprockets and the gear ratio chosen. All of this is dependent on the size of the track and racing conditions.
Who makes GM speedway engines?
Speedway Pro Ltd is a new company formed to handle the import and distribution of GM engines, engine kits and spare parts.
How much does a speedway bike weigh?

How do you stop a speedway bike?
To stop the bike, you shut the throttle and the engine does the braking. But if you need to stop the bike in a hurry, say if a rider falls off in front of you, you have to do a controlled crash – you go into an overslide and slide off the bike.
