CHAINS

Drive chains for track bikes: performance and precision in every race

The drive chain is one of the most critical elements on a track bike, as it is responsible for transferring the power from the engine to the rear wheel with maximum efficiency. Choosing the right chain can make all the difference in acceleration, throttle response and durability in extreme conditions. At BeRacing1 we offer a selection of high performance drive chains designed specifically for racing bikes, with leading brands such as DID, RK, JT and REGINA.

Technical characteristics of high performance drive chains

Advanced materials and technologies

Racing motorbike chains are manufactured with high quality materials and specific treatments to improve their performance and durability:

High-strength steel alloys: guarantee higher stiffness and tensile strength.

Titanium nitride coatings and other anti-wear treatments: reduce friction and premature wear.

Sealing with X-Ring or Z-Ring seals: improves lubrication and chain life, reducing friction compared to conventional O-Ring seals.

Chain pitch and compatibility

The chain pitch (measured in inches) is a determining factor for compatibility with the drive system. On track bikes, the most common chain pitches are:

520 pitch kits: lighter and with lower friction, used on race bikes to optimise response and performance.

525 pitch: offers greater durability at a slightly higher weight, used on medium and large displacement bikes.

530 pitch: more robust and durable, but heavier, recommended for bikes with high-powered engines.

Gear ratio and performance optimisation

To adapt the power delivery to the needs of the rider and the circuit, it is essential to choose a suitable gear ratio:

Higher number of teeth on the crown gear: increases acceleration, ideal for twisty circuits with lots of tight corners.

Lower number of teeth on the crown gear: improves top speed, recommended for circuits with long straights.

Change of the front sprocket: a variation of one tooth on the front sprocket is approximately equivalent to three teeth on the crown wheel, allowing fine adjustments in the transmission ratio.

Maintenance and care of the drive chain

To ensure maximum performance and safety in every race, proper chain maintenance is essential:

1. Regular cleaning: use specific products to remove dirt and grease residues without damaging the seals.
2. Adequate lubrication: apply specific lubricants for racing chains, avoiding the accumulation of residues.
3. Correct tension: a chain that is too tight or too slack affects performance and can compromise safety.
4. Wear check: Inspect links, seals and sprockets periodically for signs of premature wear.

Differences between a street and track chain

Drive chains designed for racing have key differences compared to conventional chains used on street bikes:

1. Lower weight and frictional resistance - optimising acceleration and engine response.
2. Greater resistance to fatigue and high temperatures: withstand the extreme demands of the racetrack.
3. Lower friction seals: reduce power loss in the transmission.
4. Increased manufacturing precision: ensure smoother, more consistent power delivery.
