ProX Clutch & Components

ProX Clutch & Components: OEM-Grade Performance for Powersports

When a clutch fails mid-moto or deep on a trail, every detail of its construction matters. ProX Racing Parts has spent decades building its reputation on precision-manufactured drivetrain and engine components, and its Clutch & Components lineup reflects that same commitment to quality. Sourced primarily from leading OEM factories in Japan, ProX clutch parts are built to the tolerances and material standards that major motorcycle manufacturers rely on — giving riders a replacement that performs like stock without the dealership price tag.

A Complete Clutch System, One Trusted Brand

What sets ProX apart in the clutch category is the breadth and cohesion of its offering. Complete Clutch Plate Sets bundle friction plates, steel drive plates, and clutch springs into a single, application-specific kit — no sourcing individual components or guessing at compatibility. ProX also carries clutch baskets, inner clutch hubs, pressure plates, cover gaskets, and rubber sets, meaning riders can address a full clutch overhaul from one catalog.

The friction and steel plates at the core of every ProX clutch kit are manufactured to exacting OEM specifications. The steel plates are precision-smoothed to promote consistent oil coverage and deliver the familiar engagement feel of factory hardware. ProX clutch springs are specially engineered with extra stiffness — typically around 10% stiffer than stock — to reduce clutch slip under the high-load, high-heat conditions of aggressive riding while maintaining predictable modulation.

Materials Built for the Abuse of Off-Road Riding

Motocross and off-road riding place the clutch under continuous stress: repeated fan-starts, sustained slipping over rocks and roots, and aggressive power delivery from high-revving two-strokes or torquey four-stroke engines. ProX addresses this by manufacturing its clutch plates from high-quality friction materials and precision-machined steel, engineered for exceptional heat resistance and reduced wear. The clutch springs are produced from high-quality, heat-treated steel designed for consistent pressure and fatigue resistance across the harshest riding conditions.

For riders who want more than a direct OEM replacement, ProX clutch baskets and inner hubs are available in billet 7075-T6 alloy with hard anodizing — a significant upgrade in rigidity and wear resistance over cast OEM units. All ProX clutch components are fully cross-compatible with each other and with factory OEM parts, so riders can mix and match as their build demands.

Wide Fitment Across Major Powersports Brands

The ProX Clutch & Components catalog covers an extensive range of applications, including popular platforms from Kawasaki, Honda, Yamaha, Suzuki, KTM, and Beta — spanning two-stroke and four-stroke dirt bikes as well as ATV models. Whether maintaining a vintage KX250, refreshing a KTM EXC, or rebuilding an ATV like the Yamaha Blaster, there is a ProX clutch solution engineered to that specific application. This depth of fitment makes ProX a reliable single-source option for shops and home mechanics working across multiple machines.
