Engine Caps, Covers and Bolts

A refined collection of engine oil caps, plugs, magnetic drain bolts, and oil filter covers designed for motocross, enduro, and off-road motorcycles. Engineered for performance, reliability, and visual detail, this collection is compatible with Honda, Yamaha, Kawasaki, Suzuki, KTM, Husqvarna, GASGAS, and other leading manufacturers.

Engine oil caps and plugs are CNC-machined from lightweight aluminum alloy and anodized in a variety of colors, including red, blue, green, and black. Each component is designed for a secure, leak-resistant seal, offering a balance of weight reduction, mechanical precision, and aesthetic appeal.

Magnetic drain bolts feature a press-fitted high-strength magnet to capture fine iron particles in the oil, helping to reduce engine wear. Available in M8 stainless steel and M10/M12 aluminum variants, each bolt includes a pre-drilled hole for safety wiring in high-vibration environments.

Also included are precision-engineered oil filter covers, CNC-machined from A7009-T6 aluminum and finished with colored anodizing. Integrated cooling fins assist with heat dissipation, offering improved thermal performance over OEM components—ideal for demanding off-road conditions.
