DrySpec D20 Waterproof Drybag Saddle Bag System

The D20 saddlebag set is constructed of RF welded 22oz. vinyl that guarantees 100% waterproof performance even when submerged. The D20 also features a rigid core construction that allows the bags to retain their shape even when empty and makes packing and unpacking super easy.

Unlike all other saddlebags, the D20’s interchangeable center strap is the core innovation that allows the bags to be so versatile. The bags mount directly to a bike with or without sideracks and can attach directly to other D-Series dry bags. Use the Velcro center strap for convenience, the solid nylon strap for extremely muddy conditions, or remove the center strap all together to mount the bags directly to a D28 or D38 dry bag. Mounting the D20 saddlebags to the D28 or D38 dry bag is the ideal solution for riders who want the extra storage but are unable to mount traditional saddlebags due to high exhausts. If you're looking to protect your soft luggage and straps from coming in contact with the hot exhaust you can purchase the DrySpec Universal Exhaust Heat Shield For 4" To 6" Mufflers.

Features:

• Modular packing (mates with D28 and D38)
• Rigid Core construction
• Universal slip-lock mounting straps (included)
• Interchangeable center straps (Velcro or solid nylon)
• Mounts with or without sideracks
• Retro Reflective logo
• Available in black, orange, or gray

Specs:

• 40 liters (20 liters each side)
• 100% waterproof (Radio Frequency Welded Seams)
• 17” long x 6” wide x 12” tall
• 22oz Vinyl & coated Cordura

With a handcrafted look that takes its inspiration from Moto GP exhausts seen on the track,

British Customs’ GP Slip On Exhaust is a unique choice for your Triumph, providing an updated alternative to the typical classic style exhausts available for Triumphs while delivering real performance benefits.

The GP exhaust is the lightest British Customs stainless steel exhaust system, manufactured from lighter 20 gauge stainless steel (rather than 18 gauge used in our other exhausts) and updated internally with our new race core instead of the heavier, louvered cores used in the Predator Pro and Sleeper Pro Slip On Exhausts. The perforated baffle core is wrapped in stainless steel packing and allows for increased air flow, less weight, and a higher pitch performance exhaust sound.

Each segment of this stainless steel exhaust system is rolled, hand shaped, fitted, and brushed in Gardena CA, manufactured with care by our expert craftsmen who leave the welds exposed to preserve and feature the craftsmanship poured into it. Design features like rubber isolated exhaust hangers reduce engine vibration and bracket fatigue, and each exhaust is finished with a riveted stainless steel end cap making the exhaust serviceable if you send it back to us for repacking.

Features

• One of the first & original "GP" designs for Triumph modern classic models
• 100% Stainless Steel Construction
• Light - weighs approximately 2.65 lbs per muffler
• Bolt-on installation using factory mounting points
• Perforated baffle core for higher engine flow, weight savings, and race sound
• Rubber isolated exhaust hanger to reduce bracket fatigue and engine vibration.
• Exposed TIG welds for a handcrafted look

NOTES: The GP Slip On Exhaust will not work with a center stand.

Liquid Cooled Bonneville T100/T120 prices are higher compared to other models due to 2x gaskets that are included for installation.

We designed the British Customs seat known as 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 custom 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 Triumph models, offering a Triumph Street Twin seat option, along with older air-cooled models, and even a Triumph Bonneville seat replacement option.

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 Triumph Street Twin custom 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
