Geco's supermoto swingarm will greatly improve the handling of your supermoto bike, as tested by top pros around the world! This swingarm fits select 2025+ competition 250-450 models from KTM, Husqvarna, and GasGas. (Does not fit PDS models!) 35mm shorter than the stock length, improving your traction, handling, and feedback. Wider opening around the tire, offering way more room even for the widest 17x5.5" setup with the tire warmer. Faster wheel changes are much easier now! Compatible with all standard fitment components: Rear wheel, axle, axle block, shock linkage, pivot bolt, bearings, chain slider & guide, as well as the brake line holder. (None of these items included) Machined from 3 solid pieces of aluminum for precise fit and tolerance. Includes the swingarm as well as the axle adjuster screws. ***For SX-F, FC, and other converted models, the Supermoto linkage is required for proper fit and performance. Linkage not required for FS or SMR (but it certainly adds adjustability!)
