YSS's new fully adjustable rear suspension from the MX range for the YAMAHA MT09 TRACER (2014-2018) has an external nitrogen reservoir with a flexible plastic hose and sits at the top position — as far as its adjustment abilities go — since it separates high and low speed compression and rebound. The main features are the following: A separate external nitrogen reservoir with a flexible plastic hose A 45mm radial piston with a 16mm hard chrome shaft High-speed compression damping adjustment Low-speed compression damping adjustment Adjustable rebound so you can control how quickly the suspension springs back after compression Threaded spring pre-load adjustment Adjustable length A hydraulic pre-load adjuster TUV certification and a one (1) year warranty Fully rebuildable
