Art of Racing anodised aluminium rear sprockets for the Cobra CX50 JR, SR, and FWE — precision-manufactured replacement and upgrade sprockets for the most competitive 50cc motocross race bike platform in the world. Art of Racing produces these sprockets in-house as part of their motocross parts manufacturing operation, making them exclusively available through the Art of Racing dealer network.
Each sprocket is CNC-machined from high-strength aluminium and hard anodised in your choice of colour. The anodising process hardens the aluminium surface to resist wear and provides long-lasting colour retention even under the abrasive conditions of motocross competition. The sprocket is drilled and precisely machined to Cobra factory dimensions for a direct bolt-on fit — no modification required.
Changing sprocket tooth count is the primary method of tuning gear ratio on the Cobra CX50. Smaller rear sprockets provide higher top speed; larger rear sprockets provide faster acceleration and stronger pull out of corners. Art of Racing sprockets are available in multiple tooth counts to allow gearing optimisation for different track types and rider levels.

Art of Racing designs and manufactures its own line of CNC-machined motocross components under the ART Racing Parts label. The manufacturing operation is backed by ALFA TEH, a precision CNC company with production experience in aerospace and demanding industrial sectors. Every ART Racing Parts component is designed, machined, and finished in Europe under one roof.
The first prototypes were developed in 2019 by a professional racer and technician working directly with the engineering team. Each design was tested in competition, refined through successive iterations, and not released until it performed in real racing conditions. ART Racing Parts components have contributed to race wins and championship results across European junior motocross competition.
The current product range includes CNC-machined anodised aluminium rear sprockets for Cobra CX50 and CX65, available in multiple tooth counts for gear ratio tuning and multiple anodised colour options. Additional components including triple clamps are produced to the same standard. ART Racing Parts are exclusively available through the Art of Racing dealer network.
