KTM has radically updated its 2023-model 125SX, 250SX and all-new 300SX two-strokes, but which of the bikes’ many changes has had the biggest impact on how they now feel to ride? Is it the all-new “anti-squat chassis” concept, which pays big handling dividends? Or is it the all-new fuel-injection system, which transforms the way these machines deliver their power? And is the first ever 300SX model genuinely faster than its quarter-litre sibling, or more of a design folly that’s aimed at those who prefer to ride than race? We answer these questions and more after sampling these three landmark models at KTM’s recent media launch in Queensland.
