High Performance

Yes, you are right, the “UPGRADE FORKS AND REAR SHOCKS ABSORBER KIT” I bought it’s GREAT: I have really increased the stability in both medium and wide curves as well as in braking. VERY SATISFIED.
Fast delivery in Europe and correct seller, absolutely recommended. A little bit attention in packaging.
Special thanks to Matthew.

Front Fork Full Upgrade Kit_TRIUMPH SPEED TWIN

I received the product faster than expected, and the installation was not difficult by referring to the video. It is not perfect yet, but the ride quality has improved. Thank you for providing a good product.

6 Stars...!

Without doubt, one of the best modifications I’ve done. The difference in the progressive springs compared to the factory springs is massive. The smoothness and stability makes the ride even more enjoyable. Equally the ability to adjust the load to stiffen the feedback is also fantastic. I can’t recommend these enough! Well done Tec!
