<p>A motorcycle turntable has a support beam (1) Fig. 1 which has retractable extensions (4) which are extended to support a motorcycle. Extensions (4) may slide or hinge in function with regard to the support beam (1). The support beam (1) is rotatably secured to the base plate (3) by support bearing (2) which has the ability to maintain the support beam (1) in the horizontal plane when the centre of gravity of a motorcycle being rotated acts through the area of support bearing (2). When the turntable is not required for use the extensions (4) are retracted when the unit may be easily moved to a storage location.</p> |
