KTM390 2025+ LEVEL 1 SHOCK LEVEL 1 Shock - STANDARD TRAVEL & SEAT HEIGHT REAR SUSPENSION UPGRADE. High quality TracTive aluminium big-bore rear shock, with adjustable damping and a choice of spring rates to suit a wide range of rider/luggage weights and applications. Along with traditional manual preload adjustment, our LEVEL 1 shock can also be upgraded with a dedicated Hydraulic Preload Adjuster (select from menu above) allowing quick and easy adjustment of the spring preload a further +/-10mm to compensate for additional loads such as luggage or a passenger. OPTIONAL HYDRAULIC PRELOAD ADJUSTER: Our Hydraulic Preload Adjuster is designed for riders that want quick, easy adjustment of spring preload. It allows the preload to be adjusted over a range of +/-10mm with the simple turning of a knob. Approximately 20 turns will achieve the full movement of the preload piston travel, and the knob has a 'click' every half-turn to aid setting. Quick tool-less preload adjustment is much preferred by those riders who wish to alter the preload/rear sag setting on a regular basis - typically when carrying extra luggage or a passenger, or when going from street to off-road travelling. Supplied ready assembled on your shock together with the correct length/rate spring selected at the point of purchase.
