Reinforced Internal and External Timing Belt by Dayco

The reinforced XTX belt is designed for road transmission, tailored for the most extreme machines powered by an engine of 800 cm³ and above. Made from polychloroprene resistant to high temperatures with a higher content of aramid fibres to enhance wear resistance. Optimised tooth geometry to promote flexibility and extend lifespan under intensive use.

Design and Materials

• High-temperature resistant polychloroprene to maintain belt stability during sustained use.
• Higher content of aramid fibres for improved wear resistance and increased durability.
• Deep teeth on the upper face and rounded teeth underneath to maximise flexibility and reduce bending stress.

Usage and Performance

• Quicker and smoother engine response at high speeds for more controlled riding.
• Improved acceleration at medium speeds for more assertive take-offs in traffic.
• Reduced slippage at high torque levels for more reliable power transmission.
• Performance validated beyond 12,000 RPM for suitability at high engine speeds.
• Better performance during deceleration for more effective engine braking.

Advantages

• OEM Reference XTX1021
• Designed for road use and suitable for urban environments
