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.
I had previously fitted the TEC front and rear progressive suspension to my 2011 Bonneville SE, as the original factory fitted are just awful. After about a year, I really was finding the front end too hard when driving over unexpected potholes, or even speed bumps. Made for dangerous driving. Just fitted the Emulators and Top adjusters. WHAT A HUGE IMPROVEMENT. I took the forks off to do the job as I was changing fork oil at same time, and it really made the job easy with forks off, especially managing those nasty little bolts that hold the dampers in. I had an air gun but couldn't get one of the bolts to undo. The trusty short broom handle down the tube did the job with no effort. TEC recommended 7.5W light fork oil which I did put in. The instruction video is for Scrambler with extended forks, so I tried with fork oil level at about 130mm below fork top, and this seems OK. With the top adjusters it means it's not so critical as I can preload or not to get perfect feel. Once again great product from TEC. A shame that the Triumph designers chose to put such rubbish suspension on in the first place. 2011 Bonny SE
Extremely fast delivery delivery to the other side of the planet. Great products.
Only slight disappointment that the was no instructions for the figment of the fork emulators. Thanks
The emulators were delivered very quickly. There were YSS instructions in the kit of how many holes and what size they need to be to take the existing damping tubes out of the equation. They are beautifully engineered. Fitting them is straightforward. Tec answered my email about reducing the spacer length to allow for the emulators and the adaptor rings provided by Tec. They answered promptly that 20mm needs to be cut off. I haven't tried them as the bike is still in bits but all reports that I have read say that they make a big improvement over the stock system.
My bonneville now handles much much better now thank you very much for help and advice
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.
