Motorcycle and car loop from Aachen
From Aachen (Eifel) we calculate the twistiest round trip in three lengths, for motorcycle and car. It runs over paved country roads without motorways. Every figure comes from the calculated route.
The app calculates a loop from your location with the same method.
Reverse: the same route backwards. Curves swap sides, the radii stay.

How it was measured
- Route: a round trip from Aachen, 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.
