B - INTRODUCTION Speedway bikes are a totally different type of motorcycle that you will see. Their design to turn left in a power slide at amazing speeds is not only exciting, but the skill needed to control these bikes is also amazing. The engines run on pure 100% methanol and the engines are all air-cooled 500cc, running on either synthetic or mineral based oils. They have no brakes and they also have no gears. Gearing is done through the ratio displacement between the front two sprockets and the rear wheel sprocket. One of the front sprockets is attached directly to the crankshaft for drive, which is in turn, connected to the rear sprocket by a drive chain. The outer sprocket is also linked to the crankshaft, but is in front of the inner sprocket and also is chain driven that connects the clutch assembly. Depending on rider choice and track conditions, the bike will be set up with a ratio for the rear and front sprockets. These are connected to the bike for quick release as they often get changed as the meeting progresses. Speedway tracks are all individual in their setup, as is every rider. The key is to maintain the optimum gearing to ride the track with maximum drive.
