YZ/WR276F Fits 2014 – Current YZ250F, YZ250FX, WR250F

Bore: 81mm Stroke: 53.6mm  Actual Displacement: 276.20cc

Includes:

We modify your OEM cylinder with a forged aluminum liner and plate it with ceramic nickel bore coating.

Custom 13.7:1 CP piston kit with DLC coated wrist pin.

Copper combustion sealing ring and groove cut into deck surface.

Necessary gaskets for install.

Notes: We really like the power gains that the 81mm bore on the YZ and WR provides.  Any larger and they get chunky feeling and the top end suffers too much.  Any smaller and you leave too much on the table.
