Yamaha YZ 250X

New 2025 Yamaha YZ 250 X Yamaha SA stripped the YZ250X, tested it, broke it, and rebuilt it multiple times, improving until it could withstand the harshest climbs, steep rock gardens, and punishing heat. The results are obvious in every detail. At its heart, the YZ250X motor remains, but Yamaha SA made some clever local modifications. The stock flywheel was increased from 7oz to 11oz, easily accommodating the Fisch Moto electric start system, a robust, reliable unit chosen specifically by Yamaha South Africa as the best option for South African hard enduro conditions. The GYTR 11oz flywheel wasn’t compatible with the Fisch Moto starter kit, so the standard flywheel was locally modified, a great example of homegrown engineering. The gearbox has also been tweaked, shortening first and second gears to give better low speed control, while sprockets were changed to 13/51 from 14/50 for improved traction when crawling over technical terrain. Cooling was a priority, the bike now sports PSP radiator braces and a 1.8 bar radiator cap with a Yamaha Cooling Fan kit, and a dual-battery setup ensures the starter and cooling fan run independently. The fan can push at full power all day without ever draining the battery fully, and a handy charging connector for quick easy hook ups to a charger.
