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.
What kind of engine does a speedway bike use?
General Speedway bikes are a unique type of motorcycle. Originally the engines used were upright, the name reflects the way they fitted into the frame of the bike. Nowadays, in order to handle the bike more effectively, speedway riders use laydown engines in their set ups.

What makes up the surface of a speedway track?
All tracks have a pit area for the riders, bikes and mechanics, this is where riders prepare for racing and make necessary changes to their machinery. The surface of the track consists of layers of grading, the uppermost consists of shale, loose materials which must be no bigger than 7mm in size.
