These Technical Regulations (‘Regulations’) are to be read in conjunction with Class Rules Chapter 9 of the 2017 Karting Australia Manual. For the avoidance of doubt, these Regulations are supplementary to the Rules and are to provide additional specific technical information for the KA2 Class. 1.1 Eligible engines
a) In accordance with Class Rules Chapter 9 of the 2016 Karting Australia Manual 1.2 Radiator:
a) The radiator style, type and size is at the discretion of the Competitor. 1.3 Wheels The use of wheels complying with the CIK-‐FIA technical drawing No. 4 (Appendix 6 of these Regulations) is compulsory:
a) Diameter of coupling for tyres: for 5 inch rims: 126.2 mm with a tolerance of +/-‐1.2 for the circumference with the hump and a tolerance of -‐1 for the diameter of rims with screws.
b) Width of the tyre housing: 10 mm minimum. c) External diameter for 5 inch rims: 136.2 mm minimum. d) Radius to facilitate the balance of the tyre in it’s housing: 8 mm. e) Maximum pressure for assembly: 4 Bar. f) Tyre burst resistance test with fluid at an 8 Bar pressure.
