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.

My bonneville now handles much much better now thank you very much for help and advice

Damper emulators.

Fitted these to a 2007 America. Installation is pretty straight forward, the only minor gripe is that the adapters are a loose fit so keeping them in place during reassembly is a pain.Certainly has improved high speed damping, but as i did a full rebuild on the forks so its a little early to appraise overall performance.

Stuart James
Economical Upgrade

Front end is more positive over rough road surfaces and dips more steady, under heavy use of front brake. You will need a sharp hacksaw blade and a good eye, when you shorten the spring spacers to accommodate the emulators. ( you won’t get the top nuts back in, if you don’t cut them)
No need for a full strip- just drain the old oil and remove the spring and spacer.

Worthwhile improvement for the money

Providing you have basic mechanical ability, you're only going to make the standard forks better. I installed these with Hagon progressive springs & TEC Fork top pre load adjusters for Triumph 41mm forks. 2011 T100 much better now.
