The standard WP suspension on the KTM and Husqvarna range can be improved, claims British suspension firm K-Tech. By replacing the air forks with a coil spring conversion and new damper unit, and altering the rear shock with a bladder conversion and new damping system, the bikes can be made simpler to maintain, offer more adjustment and are more plush.

We try out a fully-kitted K-tech KTM 125 two-stroke and a Husqvarna FC450 four-stroke, which also had one of K-Tech progressive linkages. See what our chief tester Dave Willet thought of the system.
