2021 YAMAHA YZ250F AIR BOX COVERThe new 2021 air box cover (left) has holes in it. These holes aren’t visible when the seat is on because they vent at the fuel cap. However, they do make the bike sound louder for the rider. The stock air filter also has new material to match the YZ450F.

2021 YAMAHA YZ250F TRANSMISSIONThe transmission gears received updates for durability. On both the main shaft and counter shaft, 3rd, 4th and 5th gears have an increased tooth width while 4th gear on the main shaft and 3rd/4th on the counter shaft have a new shot peened material.

2021 YAMAHA YZ250F FOOT PEGSThe foot pegs on the 2021 YZ250F (above) have a lighter and more sleek shape this year to ensure they don’t drag in ruts as easily. The 2020 foot peg is at the bottom of the photo for comparison.
