X Racer – Willy Klünder
Classic Wild Mouse by Maurer & Söhne
Operator: Willy Klünder (Minden)
X Racer Klünder – Willy Klünder's X Racer is a portable Wild Mouse roller coaster. The ride also features tight turns, rapid changes of direction and short descents. Unlike a large looping roller coaster, its special moments come on a comparatively compact track. The cars travel through the characteristic mouse turns one after another, making the speed feel particularly direct on the upper sections of the track.

Features and history
X Racer was formerly called Katz & Maus. This older name is important when researching the ride, as footage from the past could otherwise easily be mistaken for a different roller coaster. Vorlop from Hanover is listed as the former operator. Specialist overviews date the redesign under its current name to around 2015 to 2016.

Who is X Racer Klünder suitable for?
With a Wild Mouse, you should not focus only on the height. The special experience comes from the geometry of the turns and the immediate sensation of riding close to the edge of the track. If you are planning your first roller coaster ride, you can watch the track from outside beforehand. However, how well you tolerate it depends on the tight changes of direction.
Tips and appearances: X Racer Klünder
The Bielefeld showmen's association also explicitly lists Klünder's X Racer for 2026. This identifies the specific ride more clearly than a general reference to a Wild Mouse. An older on-ride video from Dortmund shows the same ride and can give you an idea of what the ride is like. You can find out the current height restrictions and fares directly at the entrance.
