Polini Evolution Clutch Bell D.107 for Yamaha / Minarelli (250.002)Category: EnginesSubcategory: Clutch SystemUpgrade your scooter´s powertrain with the Polini 250.002 Evolution Clutch Bell, a pinnacle of performance engineering for Yamaha and Minarelli engines. Designed for riders who demand maximum power transmission, reliability, and consistency, this component is a critical upgrade for both high-performance street builds and competitive racing applications. Move beyond the limitations of stock components and experience a tangible improvement in acceleration and engine responsiveness.The Polini Evolution Clutch Bell is engineered to directly address the weak points of standard clutch Housings. Under the intense stress of a tuned engine, a standard bell can distort, overheat, and cause clutch slip, leading to inconsistent performance and power loss. Polini´s solution provides the structural integrity and thermal stability needed to handle increased horsepower and aggressive riding, ensuring your clutch engages with precision and holds firm every time.Key Benefits:* Explosive Acceleration: The lightweight yet robust design reduces rotational mass, allowing your engine to rev more freely. This translates to significantly quicker throttle response and a more aggressive launch from a standstill.* Unmatched Durability: Built to withstand the extreme forces of high-RPM racing engines, this clutch bell offers exceptional resistance to wear and deformation, guaranteeing a long service life even under the most demanding conditions.* Consistent Performance: Superior heat dissipation prevents the clutch from overheating during prolonged use. This eliminates clutch fade, ensuring your scooter delivers consistent, reliable power from the start of your ride to the finish.* Vibration-Free Operation: Thanks to its perfectly balanced, high-precision construction, this bell ensures smooth engagement and power transfer, reducing drivetrain vibrations and enhancing overall ride quality.Main Features:This high-performance clutch bell is manufactured from a single, solid piece of advanced, high-resistance material, eliminating weak points like welds or press-fittings found in lesser-quality components. The entire unit undergoes a specialized nitriding heat treatment, a thermochemical process that hardens the surface for incredible resistance to abrasion and high temperatures.The structure is further enhanced by a meticulously machined reinforcing ring, which prevents any possibility of ovalization or distortion at maximum engine speeds. The entire component is CNC-machined to achieve perfect concentricity and dynamic balance, a critical factor for high-RPM stability and efficient power transmission. Its design is optimized not just for strength but also for cooling, effectively drawing heat away from the clutch shoes.Technical Specifications:* Product: Polini Evolution Clutch Bell* Polini Part Number: 250.002* Type: Performance Clutch Housings / Bell* Internal Diameter: 107 mm (D.107)* Construction: Single-piece, CNC-machined* Surface Treatment: NitridingChoose the Polini 250.002 Evolution Clutch Bell and equip your engine´s clutch system with a component that delivers professional-grade performance, strength, and reliability.
