Generation 4 PDS 2017-2019
The Xplor was introduced as a lighter weight alternative the to previous shock. It's 46mm against the previous 50mm unit. While it's lighter, the shock is great for trailriders. We soon found out even the clubman racers wanted more support in compression, more rebound control and a greater range of shock springs.
Generation 3 PDS 2012-2016
By the time we were at 2012, the PDS had stopped changing in it's design. It became a series of new settings every year. The shock was robust, the stock settings suited a lot of people but it never suits everyone. There are often some pressure balance problems in the production shock making them audibly thump on the dyno.
Generation 2 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.
Generation 1 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.
