We’ve tried this lighting upgrade out on dirt trails at night and can confirm — they work.

On top of the dramatically improved visibility, this Triumph motorcycle headlight is adaptive. On-board sensors detect your cornering angle in real-time so that light can illuminate your vision field with the lean of your motorcycle, moving with you. This proprietary technology enables the light to fill in the gaps that the factory headlight would otherwise leave in the dark. The Motodemic Adaptive LED Headlight really proved itself to us when we took it on night rides on CA-1 through Big Sur where it gets pitch black on tight and twisty roads, but we still were able to see what’s ahead.

The Motodemic Adaptive LED Headlight is manufactured in the USA by J.W. Speaker, a highly regarded producer of high performance vehicular lighting solutions. Being a higher ticket 3rd party product, we made sure that it met our expectations by equipping several of our bike builds with this headlight on numerous trips on dark trails and canyons. We weren’t disappointed by the performance of this Triumph motorcycle headlight, and also found that its unique look is a major bonus.

Specifications:

• Color Temperature: 5000K (daylight)

• Lens Type: Polycarbonate

• Power Draw: 24 watts on low, 36 watts on high

• Connection Type: H4

Features:

• On-board sensors that detect leaning angles when cornering

• Dual burn high & low beam optics for extra visibility and safety

• Plug & play installation that directly replaces the factory headlight

• DOT & ECE dual-compliant headlight

• 40,000 Hour LED Lifespan Rating

• Available in Black or Chrome

• 5 year warranty

• Made in the USA

Pro Taper Dirt Track Bar Kit

The installation of aftermarket handlebars on the 3rd gen "liquid cooled" Triumphs is not easy.

To address this problem, we have put together handlebar kits that come with everything you need to make the upgrade to a Pro Taper Bar possible.

Kit Includes:

• EVO Pro Taper Dirt Track Handlebar
• Four Bolt Clamps *Street Twin Model Only
• Lengthened Clutch Cable
• ABS Brake Line
• Brake Line Extender
• Copper Crush Washers

• Replaces intermediate/mid-pipe; bolt-on design

For Turn Out Performance Tips, please view the link here

For Bonneville T100/T120 models, please view Slash Cut Performance Tips here

Note: Will not fit EURO5 models as the intermediate/mid-pipe is welded onto the catalytic converter, starting at some 2021 models & up. To check for this, look below at your catalytic converter where the intermediate/mid-pipe joins. If there is a clamp, Performance Tips are compatible. If it's welded, it is not compatible.

We do not recommending pairing our Performance Tips with an X-Pipe as these pipes are hollow without any baffling. This can cause the engine to run poorly and/or damage the engine.

INSTALLATION GUIDE

Both the Turn Out and Straight Pipe Performance Tips install the same way. Steps will vary by bike model. See the following installation guides below:

The Upgraded Seat For the Triumph Bonneville and Street Twin

We designed the Slammer Seat back in 2013 when options for Triumph seats were really limited. At the time, the goal was to create a Triumph Bonneville seat that would give the bike a custom look without sacrificing comfort — to get away from the bulky look of stock seats and use something other than single density foam, which has been the most commonly used seat filler for motorcycles since the 1940s. Over time we’ve been able to replicate our tried and true Slammer design across a variety of Triumphs, offering a Triumph Street Twin Seat option too, along with older air-cooled models.

Watch our video below to see how our Slammer Seats are made here in the USA: https://www.youtube.com/watch?v=yKYTLbUeB0Q

Fitment Note: This seat is not designed to work with grab rails, luggage mounts, or any other accessory that may inhibit the installation of the seat on the subframe.

FEATURES

• Designed in 2013 and consistently retested
• Hybrid gel technology combines proprietary foam and a special gel core to reduce road vibrations and improve the distribution of weight
• Covered with premium Marine-grade vinyl, which looks like leather and is both durable and weather-resistant
• Easy install: plug and play design

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
