Rider Profile
| Best For | Suited to intermediate and experienced riders comfortable managing a tall, heavy 243kg machine; not ideal as a first bike. |
| Purpose | A do-it-all standard built for relaxed distance riding, commuting and two-up touring with its smooth shaft drive and big 21L tank. |
| Rider Fit | Upright naked ergonomics with a broad seat; hefty wet weight and low-slung longitudinal 'flying brick' four give planted, stable feel. |
| Character | The iconic BMW 'flying brick' - smooth, torquey, unburstable and refined, prizing effortless long-haul competence over sporty aggression. |
| Not Ideal For | Not for off-road use, tight-carving sportbike thrills, or riders wanting a light, flickable city machine. |
