CNC Fork Emulator Valves with Adaptor Rings-

This brand new pair of fork Emulators/adaptors will fit all years and models of Air cooled and Water-cooled Triumph Hinckley Bonneville, 1200 Bobber, T100, Street Twin, Street Scrambler America , Speedmaster, Scrambler and 900cc Thruxton .

These valves are made for us by YSS and are top quality.  The adaptor rings are exclusive to TEC.

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.

SE Emulator

Transformative. There are certain things that MUST be done to Bonnevilles and this is one of them. Washboard roads were causing my forks to go solid. When you look at the video you understand why. This absoloutely fixed that problem. It suggests you cut down the internal tube as well but I didnt. This has given me the perfect amount of pre load for my weight. 95kg. Thanks Tec.

Great service

Parts were well packaged and arrived in good time. Great that there is a YouTube channel to help with fitting and that Tec went to the trouble of testing the parts and then adding 2 plastic rings to ensure the parts work...which a.n.other suspension specialist does not supply/even know they are required

nice product

Bought these for my 2020 street scrambler, unfortunately they don't fit this model because it has forks with damper rod in right leg.

fork upgrade

got fork elmiators for a friend to fit his boni, so cannot really comment on them but being a generic kit for different makes, he said reading instructions are not very clear. it would be nice to see at least a basic fitting guide what to alter ect, yes I know there's a video but he has no Internet
