Why upgrade the stock part?

The R18’s stock cylinder head is functional but remains exposed to scuffs, debris and minor knocks, especially during low-speed maneuvers or parking. Its standard look can also lack personality on a refined build. Over time, micro-scratches dull the overall engine appearance and are difficult to fix.

• Direct exposure to scratches, gravel, and scuffs during maneuvers

• Less personalized visual aspect on a premium configuration

• Surface that can mark and lose its shine over time

• OEM replacement often costly for a simple aesthetic refresh

This CNC 6061 aluminum cylinder head cover addresses these limits by offering a robust protective barrier and an immediate aesthetic upgrade. Its premium finish, longevity and simple installation make it a relevant, durable, and value-adding upgrade for your R18.

Ideal use cases:

• Elegant customization of a cruiser/bobber-oriented R18

• Daily rider requiring extra protection at the cylinder heads

• Show builds and exhibitions where engine finish is paramount

• Grand touring and long distances for increased durability

• Workshops and custom enthusiasts seeking a premium plug & play base
