KTM 250 SX-F

A quarter-litre four-stroke built with one job: winning amateur and semi-professional motocross races. The 250 SX-F uses a 249.9cc single-cylinder engine that puts out 46.8PS at a screaming 14,000rpm and 26.5Nm at 9,500rpm, figures that tell you this engine wants to be revved hard, not cruised. KTM India markets it under its Factory Racing banner, and the spec sheet backs that language up — launch control and a quickshifter come as standard fitment, not optional extras, along with selectable engine maps and switchable traction control that a rider can dial in trackside between motos. Suspension is WP's XACT AER 48mm air fork and a matching WP XACT shock, both tool-free adjustable so a rider or mechanic can retune the bike between practice and the main race without a workshop. Dunlop's Geomax MX34 tyres come fitted as standard, a tyre built specifically for motocross dirt rather than road use. The bike weighs around 104kg, carries 7.2 litres of fuel, and has a seat height of 958mm — tall by any ordinary standard, but correct for a bike designed to be ridden standing on the pegs through whoops and berms rather than sat down in traffic. The published listings describe this plainly as a track-only motocross machine with no instrument cluster, no lights, and no turn signals — none of the hardware an RTO would need to see for road registration, and none of the hardware KTM bothered fitting, because this bike was never meant to see a public road. It's priced at Rs 9.58 lakh ex-showroom and sold through KTM's regular dealer booking process, the same online token system used for its road bikes, which tells you KTM treats this as a mainstream catalogue product rather than a special-order item — it just happens to be a product built entirely for competition. The buyer here is a serious amateur or semi-professional motocross racer, someone already riding at a level where a 125cc two-stroke or a smaller four-stroke has stopped being competitive. It sits in KTM's SX-F motocross family below the bigger 450 SX-F and is the engine capacity most commonly raced in the MX2-equivalent class at Indian national motocross events. Anyone buying one should plan on servicing it through a dealer with genuine off-road and motocross experience, not a general bike mechanic, and should budget for the running costs of a race bike — regular top-end work, tyres, and suspension servicing — rather than those of a daily-use motorcycle. Compared with the two-stroke small-wheel machines below it and the bigger 450 SX-F above it, the 250 SX-F is the engine size most riders in India settle into once they're racing competitively rather than just learning — four-stroke power delivery is more forgiving to modulate than a two-stroke's narrower band, while still being light enough to throw around on tighter tracks than the 450 suits. Buyers moving up from a smaller KTM or a rival brand's motocrosser will notice the quickshifter and launch control immediately, since those are still rare standard fitments even in this segment, and KTM clearly expects riders at this level to use them rather than treating them as gimmicks.
