For Bonneville and Thruxton Models

Looking to a cost effective way to increase the performance of your Triumph Bonneville or Thruxton? British Customs has designed an aluminum battery box that allows riders to remove the factory air box while maintaining all necessary securing points for replays, fuse box and starter solenoid. By removing the air box and installing the two supplied K&N filters directly to the end of the throttle bodies (EFI models) or carburetors (carb models), the motorcycle's intake system is opened up, allowing it to increase flow into the motor.

The aluminum battery box fit the battery, ECU, ECU spacer, starter solenoid, fuse box and replays while allowing the stock side covers to be fitted, allowing the rider to maintain a factory appearance. The British Customs Battery Box is constructed from aluminum and all including mounting hardware is machined from stainless steel. (Carb models only: Carb brace is constructed CNC from aluminum and anodized black.) The best known and best manufactured K&N air filters feature K&N's million mile warranty. Jet Kit includes 135, 140, and 42 pilots. All the necessary brackets, hardware, and fastening points for reinstallation of stock components are included.

• British Customs Battery Box
• Carburetor support brace (needed for carbureted models only)
