On a KTM 125 SX, a short tap on the pedal during a jump stops the spinning rear wheel, and the bike's nose drops, which levels a bike that has taken off too steeply. The disc behind that tap is Accossato's DK018, a fixed off-road rear disc listed for the 125 SX from 1993 to 2026. It is one piece of steel with a 220 mm outer diameter, a 110 mm centre and a thickness of 4 mm.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eRear disc for the KTM 125 SX, model years 1993 to 2026\u003c\/li\u003e\n\u003cli\u003eFixed off-road design, one steel piece\u003c\/li\u003e\n\u003cli\u003e220 mm \/ 110 mm diameters, 4 mm thickness\u003c\/li\u003e\n\u003cli\u003eInterchangeable with the original rear disc\u003c\/li\u003e\n\u003cli\u003eMinimum working thickness printed on the disc\u003c\/li\u003e\n\u003cli\u003eSupplied as one disc\u003c\/li\u003e\n\u003cli\u003eNo German ABE; for track use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eConstruction and Material Quality\u003c\/h2\u003e\n\u003cp\u003eAccossato places the DK018 in its off-road disc range. It is a fixed disc without a separate centre section, so the part the pads clamp is the same part that is bolted to the hub. Each disc carries its minimum thickness in print, and checking a micrometer reading against that figure takes a minute between race weekends. Accossato explains its disc design with a racing background in Superbike, Moto2 and Moto3, and says the low weight of its discs is an advantage when it comes to steering.\u003c\/p\u003e\n\u003ch2\u003eA Tap in the Air\u003c\/h2\u003e\n\u003cp\u003eThe trick works because of the rear wheel's momentum. A wheel spinning fast carries a lot of rotation; stop it suddenly and that rotation is handed on to the whole bike, which pitches forward. A short, sharp tap brings the nose down a little, a longer press brings it down further. Riders on a 125 SX learn to combine it with the throttle, which does the opposite and lifts the front.\u003c\/p\u003e\n\u003cp\u003eFor the disc, this is a different load from normal stopping: brief, sudden and repeated on every jump of the lap. Add the usual work into corners and ruts, and a rear disc on a busy track has a hard life. Keep an eye on the pedal. If its travel grows, check the pads; if it pulses under your boot at low speed, look for a bent disc. And keep the disc clean of oil and chain lube, because even a trace of either spoils the pads.\u003c\/p\u003e\n\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\n\u003cp\u003eAccossato lists the DK018 for the KTM 125 SX from 1993 to 2026, and it replaces the rear disc the bike came with. The front is covered by two Accossato discs, the DK017 for 1993 to 2023 and the DK259 for 1993 to 2024. When you fit the DK018, clean the hub contact face, tighten the bolts according to the KTM manual, and check afterwards that the rear wheel of the 125 SX spins freely without the disc binding.\u003c\/p\u003e\n\u003ch2\u003eRoad Approval\u003c\/h2\u003e\n\u003cp\u003eThe DK018 comes without German ABE or type approval.
