Hi RRATs ,
We have finalised machinery specification and race format for the 2013 season .
Please note :



Machines must comply with the GCR in terms of lockwiring etc.
Machines must be fitted with folding or shear type footrests ( Track requirement)
Engine crankcase and gearbox breathers must be fitted with hoses feeding into an oil catch
container with a volume of at least 300cc, which must be emptied after each event (Track
requirement)
Further , race format may vary due to entry numbers , timetable / event format , and other factors .
Supplementary Regulations for a particular meeting may detail these changes , or the Key officials at a
specific meeting may alter format in consideration of meeting conditions , in accordance with the GCR..
A sample entry form is included , which details race format.
