XRAY 303759 - T4'21 Motor Mount Aluminium Upgrade with Belt Tensioner  [XR-303759]

Purpose-built aluminium motor mount for consistent drivetrain feel

The XRAY 303759 - T4'21 aluminium motor mount is made to bring consistent rear belt control and added plate rigidity to the T4 2021 chassis. The single-piece aluminium construction houses an integrated belt tensioner to reduce slack and limit the need for constant belt adjustments.

Better bracing with fewer weak points

As a structural part of the chassis bracing, the mount ties together the motor area, T-brace and chassis to allow different flex characteristics. The revised layout removes the separate post used previously, cutting down on unwanted movement and improving component longevity.

Neat battery backstop integration

The motor mount features built-in provisions for the battery backstop, simplifying battery positioning and making pack changes quicker and more consistent during practice and race days.
