WP has reinvented its top-line aftermarket suspension with the new 2020 XACT Pro range, including the new Supertrax shock and new spring fork fitted with cone valve technology.

But how good is the new kit and does having a shock with adjustable high and low speed rebound damping as well as compression damping just make it more complicated fore the average rider?

MotoHead’s chief tester Dave Willet is joined by up-and-coming youth rider Jack Grayshon to put the new suspension through its paces on a range of 2020 bikes. The KTM 250SX two-stroke, 450SXF four-stroke and Husqvarna FC250 are thrashed on the rough Fatcat circuit.
