What size engines do speedway bikes have?
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. Speedway tracks are oval and vary across the country.

How do speedway bikes stop?
They tend to slide out and the rest is throttle control. To stop the bike, you shut the throttle and the engine does the braking.

How heavy is a speedway bike?
FIM regulations state that the motorcycles must have no brakes, are fueled by pure methanol, use only one gear and weigh a minimum of 77 kilograms (unfuelled). By using engine and rear wheel sprockets the gear ratio can be adjusted as required for track conditions.
What oil do speedway bikes use?
Fuels & Oils
Only pure methanol is used to fuel the bikes, because methanol makes it possible to use a higher compression ratio than with other fuels, resulting in high engine power outputs. The typical speedway smell doesn’t come from the methanol but from the castor oil (vegetable oil) based engine oil.
Which engine is used in Jawa?

How do you slide on 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.
