Fine-Tuning Transmission Efficiency with XRAY Drive Belt

The XRAY 305438 drive belt is made to improve the transmission efficiency of the X4F 2025 series. Its thin, elastic construction minimises internal drag for smoother power transfer and reduced battery voltage draw, which can lead to longer on-track sessions.

Hand-Finished for Low Friction

Each belt receives a careful hand-ground finish to reach minimal thickness while keeping strength intact. This precision gives the belt the flexibility needed for a snug fit and helps cut friction inside the drivetrain. Keeping the transmission bearings clean will further reduce resistance and preserve the belt's benefits.

Practical Installation Advice

Before fitting the XRAY 305438 belt, clear any grit or debris from the transmission and inspect the bearings. Regular cleaning and light lubrication of ball-bearings will help the belt run with minimal drag and maintain consistent performance lap after lap.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How do I check belt tension correctly?

Gently press the belt midway between pulleys; it should have a small amount of give but not flap. If tension feels loose, adjust according to your chassis manual to avoid excess wear.

Will the belt stretch over time and need replacing?

All belts will settle with use; inspect for fraying, glazing, or uneven wear. Replace the belt when performance drops or visible damage appears to keep drivetrain efficiency.

What maintenance keeps the belt performing well?

Regularly clean transmission housings and ball-bearings and remove dirt from pulley grooves. Avoid over-lubricating the belt itself; focus on bearing cleanliness to reduce drag.
