If you're looking to unleash the full potential of your Triumph Modern Classic, the British Customs air box removal kit is a must-have. This simple upgrade allows you to ditch the restrictive factory air box in favor of two high-flow K&N air filters, for a significant boost in power and performance.

How does removing the air box increase performance? The OEM air box routes air intake through the stock snorkel (located underneath the left-hand side cover), which then flows through the restricted air box to the carburetors or throttle bodies. By removing the stock air box and installing two high-flow K&N filters directly onto the carburetors or throttle bodies, you'll ensure maximum airflow for optimal power and performance.

Whether you're hitting the open road or the race track, this easy upgrade will help you get the most out of your Triumph. So don't wait - make the switch today and experience the difference!

FEATURES

• Increased airflow means more horsepower
• Improved throttle response
• Designed to work with or without side covers
• Includes Jet Kit (*carbureted models only*)

JET KIT INCLUDES

• 135 Main Jet (Qty 2)
• 140 Main Jet (Qty 2)
• 42 Pilot Jet (Qty 2)
• Needle Shims (Qty 4)

Tuning Note: Airbox delete kits for carbureted models will come with a Jet Kit for rejetting, and a support brace (due to differences in manifolds on carbureted bikes).If your model is fuel-injected, we recommend getting your bike remapped. See our Tuning Guide for more details.

Galfer Brake Kit for Triumph Motorcycles

When upgrading your brake rotors, it is recommended that you replace your brake pads as well. Installing a new rotor without installing new a brake pad will reduce the effectiveness of your braking components and cause both the rotor and pad to wear prematurely. To provide an easy solution and extend savings to our customers, British Customs has worked with Galfer USA to create a Triumph-specific rotor/pad combo that will drastically improve the braking performance of your Triumph. This is the rotor/pad combo that we run on our bikes and we recommend this set up for your Triumph build.

Rotor Description: Full floating to ensure optimum brake pad-to-rotor contact. Every high-quality, Galfer-patented Wave® rotor is made from a proprietary mix of virgin high carbon 420 stainless steel, laser cut (never stamped), double disc-parallel ground to assure perfect parallel flatness and heat treated to each specific application. KBA and TUV approved. Seamlessly replaces stock rotor. Full instructions provided along with any technical help needed! Precision made in our Galfer factory in Spain.

Features:

• Designed for both street and track use
• Keeps brake system cooler by allowing air to pass over every point of a brake pad surface
• Best friction surface of any stainless steel rotor
• Full Floating Wave® blades ensure optimum pad-to-rotor contact for maximum stopping force and feel
• Seamlessly replaces stock rotor
• Extremely predictable and consistent
• Provides outstanding performance even in the most aggressive conditions
• Drastically increases lever feel / modulation and brake torque
• Advanced Brake Pad ceramic composites ready to withstand higher temperatures than regular semi-metallic carbon brake pads
• HH friction Pad rated compounds deliver excellent feel and modulation
