Yamaha Unveils 2027 YZ Motocross Lineup, Spotlight on YZ250F's First New Engine in 8 Years

So the YZ series is a designation for competition-only models, a separate category from street-legal bikes.

Launching sequentially from September 25th — does that mean release timing staggers model by model?

An engine refined over 8 years — other manufacturers are probably watching closely how it's about to change.

Even the YZ85/LW getting a chassis and engine refresh shows an attitude of lifting up from the lower classes too.

The YZ250F's first new engine in 8 years — this must be long-awaited news for the racing crowd.
