Don’t let the talk of engine internals scare you away from your relentless pursuit of horsepower. Increasing low-end and mid-range torque and power is easier than you might expect. The British Customs’ Stage I Street Cam is a complete drop-in, custom cam that boosts performance without the need of major engine work.

The cam simply drops in – requiring only that you remove the top cover to access the stock cam. The factory cam is adequate for most riders and situations, but the British Customs Street Cam is a carefully engineered, precision upgrade that takes the Triumph vertical twin engine to its full potential.

The cam is precision ground to boost both low-end and mid-range torque, but keeps the bike streetable and reliable. Lobe center values are modiļ¬ed to in-crease both lift and duration cycles that up the ante delivering more air and fuel for bigger torque and horsepower. Valve overlap is increased but not enough to adversely affect idling.

Fits- Bonneville and Thruxton

NOTE: Cams are reground. Cam core required or pay core charge of $550.

  • Precision ground for maximum performance
