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.
