Features:
-
Eliminates rear fender, for an open-rear look

*_Thruxton R/RS Note: *_The Shockmount version of Retro Turn Signal housing does not work with Thruxton R/RS as it comes into contact with the rear shock reservoir under load. The only Shockmount Turn Signal Kit that'll work in our offering is the Flush Mount Micro LED at the moment here

Seats & Luggage
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

Handling
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
