    Features   Deeper profile for increased oil capacity. Reduced oil temperature. High Grade 6061-T6 Aluminium. CNC Machined. Ultimate durability and strength. Lightweight. Hard wearing Anodized  surface treatment. Lasting stylish look. YAMAHA YZ 250 2000 - 2024 YZ 250X 2016 2024 FACTORY IMAGE RACING Clutch Covers are manufactured to increase oil capacity and circulation improving clutch performance and longevity. The deeper profile increases oil capacity by up to 100cc helps reduce oil temperature in long races especially in extreme muddy/sandy conditions where clutch abuse is most common. Our Clutch Covers are CNC machined from a solid billet of 6061-T6 aluminium which allows thin light weight sections to be machined whilst still increasing strength and durability over standard covers. This helps to resist damage from stones/rocks/footrests and brake pedals which can hole a standard cover almost guaranteeing a DNF. Theu also feature an extra tough Black Anodized  surface treatment which drastically increases the wear resistance from boots and grit to give a lasting stylish look.
