Riding in other Classes
Riders may ‘ride up’ one era/generation in their correct capacity as a means of entering additional races. Example - A Pre 74 open bike may be entered into the Pre 74 and Pre 78 Open Classes. However it is not eligible to be ridden in the Pre 86 open Class.
Riders may not ride down an era/generation class.
Bikes are only eligible for the capacity class for which they qualify. That is Small Bore bikes may only be ridden in Small Bore classes. Mid Bore Bikes may only be ridden in Mid Bore classes etc
