XRAY 611201 Rear Cover Upgrade Kit  [XR-611201]

Precision Rear Cover for the XRAY 611201

Designed for hobbyists who demand consistent engine behaviour, the XRAY 611201 rear cover is CNC-machined to tighten tolerances on the NT18. Its aluminium construction gives a solid feel while keeping mass low so the engine remains nimble on track.

CNC Accuracy for Consistent Temperatures

CNC machining ensures each surface lines up accurately with NT18 components. That accuracy helps stabilise operating temperatures and reduces stress on mating parts during long runs.

Robust Aluminium for Reduced Wear

The alloy construction provides tougher protection against knocks and general wear than many stock covers. Together with the supplied gasket, the unit helps prevent leaks and maintains correct internal pressure.

Quick Fit with Supplied Hardware

The set includes four machine screws so you can swap the cover without hunting for parts. The straightforward fit makes it suitable for enthusiasts at all skill levels.

Whether prepping for club racing or tightening up a weekend runner, the XRAY 611201 CNC-Machined Aluminum Rear Cover offers a durable, precision option to extend the NT18 engine's service life.
