Thevalueofthewheelbasevariesaccordingtothetype of motorcycle. It ranges from1200mminthecaseofsmall scooters to 1300 mm for light motorcycles (125 cc displacement) to 1350 mm for medium displacement motorcycles(250cc)upto1600mm,andbeyond,fortouring motorcycleswithgreaterdisplacement.

4. A favorable reduction in the pitching movementgeneratedbyroadunevenness

The steering offset is the measurement of the lateral deviation,fromthemiddleofthetyrecontactsurface,tothe tracepoint.Offsetofthewheelspindlefromthesteeringaxis is measured at right angles to that axis.
