1.3b Remove “sold for street use” requirement.
Reasoning is that this will allow motorcycles not originally produced for the street to be eligible for superbike categories. Ie KTM SMR 450/ Husky FS450 in 500 Superbike, Kramer (as model and engine limits would normally allow) in Middleweight SBK, Pierbohn frames in MWSBK/OSBK (as appropriate engine size will allow).
With grids falling in many of production cup and Superbike classes it would seem to me that the club would like to boost the grids as much as possible. As a specific example this would increase the 500 superbike grid by two fold in some cases.
