Shock Mount Plug & Play Retro Turn Signals

The retro style turn signals from K&S Technologies were selected for their build quality and superior aesthetics over factory indicators. These are one of the most popular lighting upgrades for Triumph Modern Classics. Offered in Halogen or LED.

Features:

• Aluminum bodied turn signals
• Halogen version, LED version here
• Mounting brackets cut & finished & wiring assembly all done in the USA
• Plug & play harness; just bolt-on, plug in turn signal connectors into harness & play.
• Non-DOT/E-MARK

Bulb Specs:

• Air Cooled = 23W/12V
• Liquid Cooled = 10W/12V

Plug & Play Kits: We've taken the guesswork out by combining these turn signals with our high quality turn signal brackets specifically to work on Triumph Modern Classic models with our tail light kits.

FITMENT NOTES

Street Scrambler Note: After 2019, the Street Scrambler had a revision in design on the lower triple tree, with a rectifier being relocated elsewhere resulting in no more mounting holes for the Rectifier mounted Turn Signal Kits (or High Fender Bracket)

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

Compatibility Note: This is a plug & play kit meant to work directly with our tail lights with no other parts needed. Just bolt-on, plug & play. For the turn signals alone, please view here

The Upgraded Seat For the Triumph Bonneville and Street Twin

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
