Well worth installing

Early days - but less dive on braking & a smoother ride.

Martin Wedgwood
Great improvement over stock

The progressive springs smooth out the ride compared with the stock Triumph items and considerably reduce diving under braking. Just watch out if you are not fitting the preload adapters and following the video on the TEC parts page there is only one shim on the damped side fork not 2.
