2021 non live valve r, failures to date are one rear wheel bearing and one u-joint. Replaced both rear wheel bearings, hubs and brakes around 19,000 mi both u-joints at 24,000mi. This machine has used a cup or even two of oil since new but it has recently jumped to almost a full quart(1200 mile oil change intervals). New one will arrive soon, all of the "stuff" from the old one will move over then the '21 will be for sale in st George utah if anyone's interested. I'm thinking about $8000🤷♀️
