This was an ultra-lightweight machine of the Miniature type. The Kempton had a 124cc ohv ABC engine previously used in the Skootamota and which had its horizontal cylinder facing forwards. It was coupled to a two-speed gearbox by chain, with belt final drive. It also had a Willis carburettor and 26-inch diameter wheels.
Because the motorcycle was aimed at those who lacked confidence, the frame layout gave a low seating position and a feeling of security, as the top tube sloped steeply down from the steering head.
