CHAINS AND SPROCKETS

Drive system: chains and sprockets for track bikes

The drive system is a key element in the performance of a track bike. Choosing the right chain and sprocket can make all the difference in acceleration, top speed and engine response. At BeRacing1 we offer a selection of high performance products to ensure maximum efficiency on the track.

Importance of an optimised drivetrain

The final drive system of a racing bike consists of the chain, the sprocket and the drive sprocket. These components work together to transfer power from the engine to the rear wheel efficiently.

An optimised drive system allows for:

1. Improved acceleration and throttle response
2. Reduced friction and wear
3. Increased durability in extreme conditions
4. Optimised gear ratio for each circuit

Drive chains for track bikes

Drive chains are one of the most critical components of a racing motorbike. In racing, chains must be light, strong and have as little friction as possible.

Types of chains according to their use in racing

Chain seals (O-Ring, X-Ring, Z-Ring)

Ideal for high performance bikes

Longer life and less maintenance

Designed to reduce friction without compromising strength

Sprocketless chains

Lighter weight and lower friction

Require constant maintenance

Used on racing bikes where performance is a priority

Chain maintenance

To maximise chain life and performance, proper maintenance is essential:

Frequent cleaning with specific degreasers

Lubrication with special greases to reduce friction and wear

Proper tensioning to avoid loss of power or premature wear

Sprockets for track bikes

Sprockets play an important role in power transmission. Depending on the material and the number of teeth, the response of the bike in acceleration and top speed can be adjusted. Sprocket materials

1. Steel sprockets: More durable, but heavy. Recommended for strength and long life
2. Aluminium sprockets: Lighter, improving engine response. They wear faster than steel sprockets
3. Combined sprockets (aluminium and steel): Aluminium structure with steel teeth. Balance between durability and lightness.

How to choose the best sprocket set for your track bike

1. More teeth on the crown gear: Increases acceleration, but reduces top speed
2. Fewer teeth on the crown gear: Higher top speed, but less acceleration
3. Sprocket ratio: A smaller sprocket combined with a larger crown wheel improves acceleration

Gear ratio and its impact on handling

The gear ratio is key to adapting the bike to each circuit. The right setting allows the power delivery to be optimised according to the track layout.

Circuits with many tight corners: Shorter gear ratio (more teeth on the crown wheel)

Tracks with long straights: Longer gear ratio (less teeth on the sprocket)
