jimmyl Posted August 24, 2011 Report Share Posted August 24, 2011 2 stroke 2 map switches normally alter ignition map. Fuel injected bikes -4rt and presume new Ossa can alter ignition and fuel maps. Hence soft and a more aggressive set up can be stored and activated via switch. Quote Link to comment Share on other sites More sharing options...
