Fork Cartridges from YSS


World Class Suspension.


Larsson UK have an extended range of replacement performance fork cartridges from YSS Suspension. We offer YSS Open & Closed Cartridges for road, track and off-road with new models being regularly introduced. Fitments include Maxi scooters, Adventure bikes and Harley-Davidson models.

The replacement of the complete fork cartridge gives a relatively quick and simple to fit upgrade to the OE fork, which may be compromised in performance by cost constraints and greater bias for use away from the sporting arena. Additionally, replacing the cartridge retains the flex characteristics of the original inner and outer tubes, that are designed with the frame as matching components of the bike chassis.

In all YSS Cartridges, the special aluminium piston and the high-flow Compression and Rebound Adjusters guarantee an excellent response under all conditions. Damping functions are separated – compression in one leg and rebound in the other. This gives precise operation and there is no effect on compression when adjusting rebound and vice versa. Road and road racing models offer fork top Spring Preload Adjustment that enables riders to set the static sag, enabling full fork adjustability. Selected kits come with alternative spring sets allowing the ultimate set-up to match conditions.

In the YSS Closed Cartridges for off-road and premium road/track focussed bikes, the primary damping oil is separated from air. This eliminates the possibility of oil being aerated under heavy use – known as cavitation. If this occurs, damping is reduced, the fork can suffer a lag between fork movement and effective damping action and the aerated fork oil is less effective as a lubricant for the internal fork components. Cavitation becomes a factor under sustained hard use – such as on the racetrack, but the YSS Closed Cartridge provides the ‘gold standard’ for fork control to the demanding rider and under race conditions. Full adjustability is on offer with the YSS Closed Cartridge. On MX bikes, the unmistaken YSS-feel gives it a very smooth response, eliminating harshness while building up a progressive damping profile toward the end of the stroke.

The YSS Open Cartridge provides a more economical performance upgrade for lighter and mid-sized road biased machines. This includes fitments for bikes originally fitted with basic damper rod forks – such as the Yamaha MT07, giving a vastly improved level of control. The YSS Open Cartridge offers 3-way adjustment allowing riders to fine tune response to machine loading, riding conditions and personal preference. Easy to access threaded preload adjusters are on the fork tops, plus rebound and compression adjustments on separate fork legs.
