Aluminum Sprocket for KTM - N Shaped
The NIBBI Racing Aluminum Sprocket for KTM - N Shaped combines lightweight 7075-T6 aluminum construction with a distinctive N-inspired internal cutout pattern. CNC-machined and finished in signature orange anodizing, this rear sprocket is available in 49T, 50T, 51T and 52T options for compatible KTM motocross, enduro and off-road motorcycles.
N-Shaped Cutout Architecture
The N-Shaped version brings a more recognizable NIBBI visual identity to the drivetrain while retaining the same core mounting specifications, material and gearing options as the standard version.
The inner section uses repeated N-inspired CNC-machined openings to create a more recognizable visual structure while removing unnecessary material from the sprocket body. The result is a lightweight design with a clear NIBBI racing identity.
The orange anodized surface complements the N-shaped machining and gives the drivetrain a highly visible performance appearance while adding surface protection to the aluminum body.
Performance Material Meets Signature Design
CNC-machined from high-strength 7075-T6 aluminum alloy to provide a lightweight alternative to conventional steel rear sprockets.
The N-inspired internal openings remove material from non-tooth areas of the sprocket while creating a distinctive visual identity unique to this version.
The orange anodized finish provides additional surface protection and gives the sprocket a clean, high-visibility racing appearance.
The sprocket profile incorporates grooves intended to help move accumulated dirt and debris away from the chain contact area during off-road riding.
Aluminum material combined with extensive CNC machining helps reduce sprocket weight compared with a conventional solid steel design.
Available in 49T, 50T, 51T and 52T to provide multiple final-drive gearing choices for different motorcycle setups and riding conditions.
Available Tooth Counts
Choose the rear sprocket tooth count according to the motorcycle setup and required final-drive ratio.

Before ordering, verify the motorcycle model and year, sprocket bolt pattern, inner diameter, bolt-center dimensions, chain specification and required tooth count. Changing rear sprocket tooth count changes the final-drive ratio and may affect acceleration, engine RPM and speed characteristics. The N-shaped cutout refers to the internal sprocket-body design and does not alter the requirement to verify mounting compatibility with the original sprocket.
