KTM WP 48mm Dual Chamber PHASE 4 with factory bladder system, first prototype, departs for Texas today, MX and Off-Road testing. Kit includes M6x.5 die, 13mm spanner wrench, four vials of 215.VM2.K5...and a SMART Performance cup holder (assuming it will as smooth as the KYB USD PHASE 4). Should be about $260...or less. Fairly easy to install. Very tunable.
