    These springs, along with the TEC rear shocks have totally transformed the ride & handling of my bike – highly recommended

    Heard lots of reviews about these springs, as everybody else reports, the standard front suspension is not very user friendly …. swopping both springs took less than 30 minutes and the feel of the bike changed instantly. Apart from improving the comfort of the ride, there is less vibration on the mirrors at 65-70mph These springs are an enormous improvement on the standard ones highly recommended…. now I need to fit the rears ! ! !

    Good thing to do to have better ride, it also reduce vibration in some how ..

    Bought last year but only gotten around to putting pen to paper! A must buy for a bonnie. Instant improvement over stock springs. Best paired with new rear shocks to really get the full effect. Excellent product again from TEC.

    Theses springs are a must for anyone running stock front springs in a Bonneville.
    I ordered the springs on a Wednesday lunch time and they arrived the very next day, all this despite TEC’s site saying they were closed for their annual holiday’s.
    The springs took less than an hour to fit, and the improvement was apparent immediately the first time I rode after fitting.
    Without doubt the best £55 you’ll ever spend on your Bonneville.

    Just fitted a set of these in place of the stock springs. Very easy DIY job. Made a fantastic difference to the ride, really impressed given the cost. This in addition to a set of rear Hagon shocks have made a great improvement to the bikes handling.

  8. Darren N.

    Exelent product and excellent customer support!

    Cuts the diving by about 50%. Makes the front suspension a bit stiffer which it needs and stops the diving under all breaking. The standard springs are too soft.
    Coupled with the rear springs and its a much nicer ride.
