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
