HEL Stainless Steel Race Spec M10 x 1.25 Double Banjo Bolt

  Designed specifically for motorcycles and high-performance racing bikes, the HEL Performance Race Spec Stainless Steel Double Banjo Bolts are engineered for dual-line brake and clutch systems where safety, durability and precision are vital. Each bolt is CNC-machined in the UK from premium stainless steel and features a pre-drilled hex head for lockwiring - a critical safety feature for motorsport use.

The pre-drilled hex head accepts 0.8mm stainless lockwire, ensuring the bolt remains secure under extreme vibration and high-performance riding conditions.

  In addition to motorcycles, HEL Race Spec Double Banjo Bolts are also suitable for use across a wide range of motorsport vehicles - including race cars, rally cars and other competition builds - wherever a compact, dual-line hydraulic connection is required.

  Manufactured in the UK and trusted by riders and race teams worldwide, these bolts offer outstanding corrosion resistance, precise fitment and consistent performance. Lockwire-ready and track-proven, they're made for racers who demand total reliability from every component.
