    Features High Grade 6061-T6 Aluminium. CNC Machined. Ultimate durability and strength. Lightweight. Hard wearing Anodized surface treatment. Lasting stylish look. YAMAHA YZ 250 2000 - 2023 YZ 250X 2016 - 2023 FACTORY IMAGE RACING Ignition 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 gear pedals which can hole a standard cover almost guaranteeing a DNF. Our Covers also feature an extra tough dark black Anodized surface treatment which drastically increases the wear resistance from boots and grit to give a lasting stylish look.
