These valves are made for us by YSS and are top quality.
The 41mm Triumph forks fitted to the Bonneville/classic twin range are renowned for poor damping and harshness over sharp bumps. These valves totally transform the damping to the level of cartridge type forks and allow separate compression and rebound damping settings. More importantly they add a high speed damping valve to allow forks to compress faster over severe bumps without compromising normal damping performance.

IMPORTANT- Several companies including suspension specialist sell these YSS valves without the TEC Triumph adaptors. It is very important to only use these with the adaptors as the will not work correctly without them and the valves may also be damaged.

Can be used with our progressive fork springs and fork top adjusters to give a vastly improved front end set up that is fully adjustable for damping and pre-load /ride height.

The kit features:-

  • A pair of High quality YSS wear resistant black anodised finish emulator valves
  • A pair of TEC Triumph 41mm fork adaptor rings.
  • They can be fitted by most competent home mechanics , please watch our video see link below.
  • Allows damping to be fully adjustable with separate adjustment to rebound, high and low speed compression damping.
  • Allows easy fine adjustment of the front forks and allows you to upgrade your forks up to cartridge fork spec at a fraction of the price.
  • Full technical and warranty back up from a long established UK family company.

Excellent improvement in the speedmaster front suspension, fitted the fork emulators, drilled the damping rods and used 15w oil, really happy with the result.

Triumph Emulators.

As you said the best initial mod for my Bonneville forks. Could not believe the difference I can now at least feel what the fronts doing and look forward to some descent weather me to enjoy the bike even more. Thanks TEC I,ll be back for the rear shocks very soon.

these emulators smooths out them pot holes.

I've just got and installed the emulators at the moment, didn't wont to do to much in one got.
As I wanted to see the difference in each stage changes.
kept the same oil what was in there for now, and there is a difference to the ride, it takes the harsh damping out, so all good.
will be getting the progressive springs latter, then the rear shocks.
riding the 2018 steetcup.

Fork emulators

I´d allready installed emulators, progressive springs and preload adjusters, change oil to SAE 7,5. Tried just on short track, because of weather, but I feel huge difference. I´ll play little bit with preload. Allready installed TEC rear adjustable shocks, rebel 2-1. Thank you TEC for suggestions and advices, that helped me to change my bike. :-) Extraordinary services
