1"-2" lowered. Asymmetrical monotube damper kit with FST damper. Threaded pre-load adjuster with 11 turns of adjustment. Progressive rate spring. No modification to forks required. The asymmetrical design places a preload adjuster over a progressive rate spring in one leg and an aluminum monotube; high pressure; nitrogen charged; sealed cartridge damper on the other. The tunable pre-load with Frequency Sensing Technology (FST) dampers and custom tuned progressive rate fork spring offers better road holding; better resistance to front brake dive; less susceptibility to bottoming out and improved stability in cornering. Comes as a complete replacement kit including all internal fork components; apart from the fork tubes and oil. Note: Compatible with 49mm fork models; with not fit inverted fork models.
