What 390 Adventure R owners actually watch
- Ridden offroad, the air filter is a consumable. Check it every ride in dust, not every service.
- Spoke tension check after the first 1,000 km of trails, then at every service.
- The 21 inch front takes tube-type rubber: carry the tools or learn plugs are not an option.
