"Those who turn left on ice and dirt with old methanol fuelled racing motorcycles. Some of the riders are former speedway and/or ice racing stars, some are greyhaired beginners. The motorcycles are genuine racers, not modified street bikes. Engines run on methanol with a compression ratio 14-15/1, and a capacity of 500 cc. There are no brakes, and only one low footrest on the right hand side."
