  1. Ambros W.

    Highly recommended!
    Kind regards from Austria

    Really easy to fit (I recommend watching the TEC video “Triumph Street Twin TEC front fork upgrade kit fitting guide” ( They have made a noticible improvement to the feel of the bike, but for the best effect, upgrade the rear shocks first. The Thruxton upgrade shocks (15 position damping as well as preload adjustment) are a revelation. The previous wallowy back end on uneven roads is gone. All in all, £200 has transformed the bike! Best money you’ll ever spend.

    They should have had these installed at the factory

    These are a big improvement over the stock springs.

    They were easy to fit (the hardest part was supporting the bike without the front wheel as I don’t have a center stand).

    I was advised by a Triumph dealer where I bought the replacement fork oil to drain the old oil overnight – this was worth doing as a surprising amount of really dirty oil came out at the end (my bike is 9 years old).

    Worth noting, after doing this my forks got stuck in the compressed position, and no amount of pulling could get them apart. The solution was simple – I put a broom handle inside them and tapped it on the floor, and full movement was regained.

    This was the only issue I had, and nothing to do with the springs.

    So, if you are thinking about these springs, get them, and replace them yourself. The springs make a big difference, and the job itself is easy.
