How it was measured
- Route: a round trip from Bastia, calculated on road data from 3 Jul 2026. Of several possible loops of the same length we show the one with the most rideable curves. Motorways are excluded.
- Vehicle: The route is calculated for a motorcycle and runs on paved roads. A car can drive it too. On narrow stretches a car route can differ in detail.
- Curve: a turn in one direction of at least 35 degrees. The DriveBattle app counts the same way.
- Radius: the tightest curve radius inside the curve. Turns at junctions are flagged and do not count towards radius, tightest curve or passage.
- Elevation: ground height along the route, smoothed over about 450 m. A climb counts from a 5 m height difference.
- Calculated on 5 Oct 2026. The figures describe this route. The state of the road on the day you ride can differ.
