Yamaha’s 2023 Outlook and the Revamped YZ250

2023 promises to be a landmark year for Yamaha. The brand’s professional Supercross and motocross race team is gearing up to make a significant impact, boasting multiple No. 1 plates and being backed by some of the most formidable talents in the pits. Amidst the palpable excitement for the upcoming race season, another major revelation is the introduction of new two-stroke models. After a considerable hiatus, significant updates are being rolled out for the YZ125 and YZ250.

A brief history reveals that since 1974, Yamaha has consistently introduced new two-stroke motocross bikes, catering to the dedicated YZ125 and YZ250 enthusiasts. Over this 48-model-year span, the YZ250 has clinched victories in AMA Motocross, with notable champions including Gary Jones (‘ 72), Bob Hannah (‘ 78-79), and Rick Johnson (‘ 84). The success story continues in Supercross, thanks to the prowess of riders like Pierre Karsmakers (‘ 74), Bob Hannah (‘ 77-79), Mike Bell (‘ 80), Jeremy McGrath (‘ 98-00), and Chad Reed (‘ 04).

Although four-stroke machines have become prominent in elite racing circuits, Yamaha’s two-strokes have maintained their allure. The YZ250, in particular, has attracted a diverse range of riders. Recognizing this, Yamaha unveiled the off-road-specific YZ250X in 2016. With its competitive pricing, streamlined design, and unique maintenance attributes, the YZ250 remains a practical choice and a thrilling ride. Robust sales figures and a passionate consumer base ensure these machines retain their iconic status.

Diving into the 2023 Yamaha YZ250 Upgrades

  • Bodywork: The 2023 YZ250 showcases a revamped look. New additions include a redesigned seat, front and rear fenders, front number plate, radiator shrouds and louvers, side panels, airbox, subframe, and fuel tank. Simplified assembly is evident with fewer 10mm trim bolts, and an 8mm T-handle facilitates easy removal of most plastics. A repositioned single-seat bolt is another noticeable change.
  • Suspension: The KYB Speed Sensitive System (SSS) fork has undergone updates, now sharing structural elements and spring length with the four-stroke variants. There’s enhanced damping force at low-to-mid speeds and a stiffer spring rate of 4.4 Nm. While the fully adjustable KYB shock with its 18mm shaft remains, it now features new internal settings and a stiffer 50 Nm spring rate.
  • Brakes: The braking system of the YZ250 has received substantial upgrades. The front boasts a larger piston size, increased caliper rigidity, enhanced brake pads, and a disc with an expanded surface area. The rear introduces a lighter caliper and hanger paired with a 240mm disc. Both discs have been optimized for heat absorption.
  • Tires/Drive: Weight reductions are evident in the chain and rear sprocket. The bike now sports Dunlop Geomax MX33 tires, replacing the previous Geomax MX52.
