The 2013 SA Motorcycle championships head into uncharted terrain on November 2 as both the 2013 National Superbike and 600 Supersport title final meeting will be held at the Red Star Raceway in Johannesburg.The four-kilometre circuit has never hosted a National championship so it' likely many riders will be unfamiliar with its 13-corner layout. Each category will tackle two 12-lap races on with 600 Supersport competitors confined to the same set of Michelin tyres for both races and qualifying.Michelin’s motorsport expert Wayne Doran said: “Red Star Raceway is unknown territory for us... and it's be hard to predict handling characteristics. As always, the experienced riders will find better race-settings than others, and we do not expect huge upsets in the results.”SA SUPERBIKE BATTLEClinton’s Seller (Kawasaki) has been crowned 2013 Superbike champion.
