Custom-machined primary cover for Harley-Davidson Milwaukee-Eight Touring models
The INCA KING M8 Primary Cover is designed and manufactured by INCA KING for Harley-Davidson Touring motorcycles equipped with Milwaukee-Eight engines.
Its large machined metal profile replaces the plain factory appearance with a cleaner, more distinctive custom look. Detailed surface machining and layered contours give the left side of the engine a stronger mechanical and performance-inspired character.
Designed for riders building Performance Baggers, custom Touring motorcycles, or complete color-matched Harley builds.
Key Features
Original INCA KING Design
Designed in-house by INCA KING specifically around the primary drive area of M8 Touring motorcycles.
The cover is intended as a functional exterior replacement and styling upgrade rather than a simple stick-on decorative piece.
Precision-Machined Metal Construction
Manufactured using precision machining for clean edges, detailed surface geometry and a premium metallic appearance.
The machined grooves and contours are integrated into the overall design to create a more technical, performance-oriented look.

- Fork components
- Wheels
Multiple Color Options
Available in:
- Black
