Best upgrade yet

I have a 22 plate Speed twin and had a few bits from tec, tail tidy, sump guard all been really good and fitted the bike perfectly. I wasn't sure about the shocks but wow they transformed the bike! They look good weigh less and let the bike turn in nicely and not wallow mid corner. My only minor gripe would be some better instructions as these are slightly different to on the video. But that really is minor compared to how much better the bike handles.

I recently fitted new shocks to my 2022 triumph speed twin supplied by Tec parts. Disscribed in one word awesome. It’s early days yet, but my bike seem to be handling much better. I set them on the softest settings as advised and they are much harder ride but they say they will get softer ones bedded in, so l can then adjust to my preference. The black and chrome Finnish goes well against the smoke grey colour my bike is. Thank you Tec parts excellent service, and good guality for the money. I would have no problem recommending this company to my friends. Once again. Many thanks Roger.

Great product and exceptional bang for buck. Shipping was fast all the way to New Zealand, Made a huge difference to the handling. I can't praise TEC enough!! Andy

great upgrade

the springs were kind of stiff at first, but only took a couple of hundred miles to break in. I'm now feeling the handling improvements. I like that I was able to raise the rear of the bike just slightly to give it more turn in. One surprising improvement was improved launch and acceleration. I didn't realize how much the stock springs sagged under hard acceleration. definitely comes off the line better now and the mid range acceleration comes on stronger too. looking forward to tuning them more to see what else I can get out of them. Oh, and they look really nice too. love the chrome springs over black.
great purchase!
