- Triumph Bonneville, Thruxton, Scrambler (toutes versions 2001-2016, 790/865cc)
- Triumph Street Twin, Street Cup (900cc, 2016+)
- Bonneville T100/T120 (900/1200cc, 2016+) 

Note 1: on Bonneville versions with alloy/mag wheels, you will need to correct the pitch by shortening 30mm the upper spacers (those that are interposed directly on top of the spring).

Note 2: on Street Twin/Cup, these springs will only fit with our pre-load adjusters (here), you need to order both !

Not suitable for America or Speedmaster, nor for Thruxton 1200 R.

We guarantee that you will be amazed with the result!

The main difference is that these springs are progressive, that is to say multi-frequency, while the original springs are single frequency (single spring, the loops are regular).

The length is the same as the original, these springs do not change the height of the bike. Length 33cm for Bonneville/Scrambler, 31.5 cm for Thruxton.

Sold in pairs.


Pretty easy mounting, with basic tools. No modification of the bike required, installation is completely reversible.

12 month warranty.

Montage assez simple en opérant ressort après ressort, mais pas irréversible sur une Bonneville Newchurch car il faut réduire la hauteur des cales d'origine. Plus confortable, détente moins sèche, et avec des amortisseurs arrière également changés, belle amélioration de l'amortissement et du confort.
