I
almost picked up one of these for racing couple years ago. Luckily I wised up and figured it would be stupid to crash such rare gem. At least Ninja 250 is more "disposable".
There was regulation limiting power to 45bhp and Honda used different smart-cards with de-tuned ignition-map to lower later generations to that. Earlier ones were closer to 50-55bhp. Dave Moss's CBR250RR gets times similar to 600 SuperSports... hmmm....
