Although Yamaha is the only Japanese motorcycle company offering two-stroke dirt bikes, the tuning fork folks are not resting on their laurels. The 2023 Yamaha YZ250X off-road cross-country racer benefits from several updates. Let’s go over what’s new.
- Yamaha has redesigned the intake. It’s straighter, which Yamaha claims increases low-end and mid-range torque.
- The motor is still a reed-induction design fed by a Hitachi Astemo Keihin PWK38S carburetor—no EFI, yet. However, the 38mm carb does have a throttle position sensor and power jet for improved performance.
- With more power down low, the clutch gets new pressure plates. The goal is to improve resistance to heat. The transmission is still a five-speed, and the clutch continues to be actuated by a cable.
- If you’re going faster, you need to stop with more authority, so Yamaha has upgraded the brakes. Both ends get new rotors, though the diameter is unchanged. Up front, there’s a new caliper with increased rigidity and larger pistons.
- The radiator shrouds have been tucked in, and the seat flattened. This will make it easier to move around on the 2023 Yamaha YZ250X.
- KYB suspension returns with a shock update. The shock gets Kashima Coat internals for smoother action. The fork is still the outstanding Speed Sensitive System unit we all know and love.
- The rear sprocket is lighter this year. The wheels are unchanged—Excel rims with Dunlop Geomax MX33 tires mounted.
- There are new graphics and a new price for the 2023 Yamaha YZ250X. Team Yamaha Blue continues to be the color offered, naturally. The MSRP increases $200 to $7999, and the motorcycle should be on the showroom floor of your local dealer right now.
