Hello, time to change shocks on my Yamaha XT660R has arrived. I'm trying to find something more competitive than my old OEM stuff. I've started to do some more serious offroad beside my everyday road use. I've checked between Ohlins, Hyperpro, YSS, Wilbers, Bitubo and others. In the end I come up with two models: Wilbers 640 and Bitubo XZE0. Both have rebound and preload regulation. What do you think, are they good for offroad? Which would you choose? Would you recommend something else? By the way the payload on motorbike would be between 150-160 kg. Thanks for your answers.
