Arrived the next day. Never heard of YSS before but apparently a Thai company. Manufacture and build quality look good for the price. Finish is nice too. A doddle to install and setup. Just make sure pre load adjuster ring grub screw is accessible before installing, will make life easier if you need to make more adjustments later on. Much better shock than the OEM stock. Time will tell but nice ride, no wallow or shudder. Two up touring will be the test!
