Wilbers Promoto fork springs radically change the behavior and comfort of your bike - you will not believe it at first!

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). As a result they react much better to a range of road surfaces and irregularities.

Designed and made in Germany by Wilbers, a large specialist of motorcycle suspensions since 1985.

The springs are made from a chrome-silicone spring steel developed specifically for Wilbers, to guarantee a precise behaviour as well as an excellent durability (no squashing over time).

The length is the same as the original, these springs do not change the height of the bike:
- 330 mm Bonneville 2001-2015
- 315 mm Thruxton 2004-2016
- 330 mm Scrambler 2006-2016
- 320 mm Street Twin, Street Cup 2016+
- 270 mm Bonneville T120 2016+

Sold in pairs.


Easy fitment, with basic tools.
No modification of the bike required, installation is completely reversible.

12 month warranty.

Pas spectaculaire en ligne droite, le changement se sent vraiment en courbe, même bosselée (surtout bosselée); et sur les changement d'angle. Ces ressorts apportent vraiment un gain de confiance dans le guidage du train avant. montage simplissime.

Très très bien.
Enfin un peu de consistance à l'avant.
Changés en même temps que les amortisseurs YSS.
J'ai mis de l'huile 10W Motul (2 X 600 ml). Je pense que de la 15 ou 20 serait plus en adéquation avec l'arrière qui travaille plus ferme qu'à l'avant.
A tester à la prochaine vidange...

Excellent, le comportement de la moto est vraiment différent, il est beaucoup plus précis et l'effet pompe à vélo a disparu.J'ai retrouvé une moto saine et sûre du train avant, rien à voir par rapport aux ressorts d'origine.
Que du bonheur!!!
