19-210 Motorcycle Fork Springs
RRP $218.90

With its simple and unique Link-less rear suspension, it is light and quick reacting, but it's tricky to tune so needs a lot of knowledge and experience to get the most out of it. We've found that changing the springs can make big differences, and have developed a huge range of both linear and progressive springs to fit the WP PDS Shock.
Forks
A WP fork, it was initially a 43mm fork up to 2002, then a 48mm. The early forks were great for their time but were very under sprung by modern standards, normally in the 0.40 to 0.42kg/mm range for the 4 strokes. We did a lot of work on them at the time, and they can be brought up to a high standard with dyno work and our specially developed hi-flow pistons to cater for the 14mm damper shafts high displacement.
Shock - First Gen PDS - 1999-2007
This was the First Generation of the PDS rear, and was often maligned for its "Pilot Discharge System" character. A lot of this came from the very soft spring rates though, not the dampening. We started manufacturing Progressive and linear shock springs for the WP PDS back in 2004, before moving onto our tapered wire springs in 2006. We still keep the heavier P20, P25 and P30 shock springs for the early PDS.
We have run the old PDS shocks on he dyno, and they can be made to work with not much fuss.
  • WP PDS Shock Revalve & Service. The rebound needles can seize in these early shocks so they are part of any routine shock service for us, adding a little cost compared with japanese built shocks like Kayaba and Showa. We also put in specific settings for your weight and how you intend to use the bike.

    New Shock Spring Approx $200.00

Shock - Second Gen PDS - 2008-2011
With the Second Generation PDS, a change in shock angle meant a lighter rate shock spring must be used. The shock was improved over the earlier version with a Hi/Lo adjuster, and a revised rebound mechanism, however it was still prone to seizing.
The shock is often described as harsh, but we have specific force targets to achieve on our shock dyno that are proven to take the harsh feel out of the PDS, without replacing pistons and telescopic needles and adding to the cost.
  • WP PDS Shock Revalve & Service. We disassemble the rebound adjuster on every service, and we keep the rebound adjusters in stock as it's common to find them snapped off in the shock clevis. We even have a jig to drill the broken adjusters out.
