Something a bit different on our dyno! The gas turbine powered 52 Express Land Speed Record Bike, recently in for testing the transmission under load on our Dynapack hub dyno.

The 52 Express is a project with the aim of setting the Motorcycle World Land Speed Record and will be ridden by Guy Martin.
The project is led by former GP and TT sidecar racer Alex Macfadzean.
