Wilbers Promoto fork springs - they 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.
Sold in pairs.
Easy fitment, with basic tools.
No modification of the bike required, installation is completely reversible.
12 month warranty.
