We're an official importer and dealer of OTK, stocking genuine parts across the full OTK range: OTK Accessories, Air Boxes, Rear Axles, Body Work, Brake Systems, Bumpers, Cassettes & Bearings, Sprockets & Chain & Guards, Engine Mounts, Exhaust Cradles, Fuel Tanks & Fuel Line, Floor Plates, Hubs, Pedals & Extension Kits, Seats, Stub Axles, Steering, Torsion Bars, Water Cooling, Wheels, Weights & Cables & Locks, and Bolts & Nuts & Washers. Each part is manufactured to fit within a specific CIK-FIA homologation, so hub bore diameter, mounting points, and bearing specifications stay consistent across Tony Kart, Kosmic, Exprit, Redspeed, EOS, Gillard, Carlos Sainz CS55, and LN (Lando Norris) Kart, meaning a part specified for one fits the others without adaptation.
Brake systems are stocked down to the specific caliper and pump model, not just as a general category, since fitment depends on which OTK caliper generation your chassis uses. The wheel range includes OTK's MXC magnesium wheels, which remove heat from the tires faster and are lighter in weight than aluminum wheels. Hubs are also available in magnesium alongside aluminum, giving a similar weight-saving benefit in other rotating components. Torsion bars adjust chassis stiffness, changing how much the frame flexes through a corner, while eccentric multi-hole bushings at the stub axle allow camber and caster adjustment. Rear axles come in 25mm, 30mm, and 50mm diameters across ten hardness grades, where softer grades flex more for extra grip in fast corners and harder grades sacrifice some of that grip for more traction and stability under braking.
Why buy OTK parts from Koene
We're an official importer and dealer of genuine OTK parts, not a reseller of unverified stock, and we hold the full 8-brand range with class-specific variants (KZ, DD2, Junior, Senior, Mini, Rookie) in stock rather than a partial catalog. Combined with fast shipping from our own Netherlands stock and karting-specific technical knowledge built up since 1992, that means correct fitment the first time, not a guessing game between generic listings.
