Cylinder Works has three new cylinder options for 2014-2015 YZ 250F and the brand new 2015 YZ 250FX and WR 250F.  

Now you have the aftermarket option of a standard bore replacement cylinder, a 14.2:1 high compression option, and a bolt-on +3mm 270cc big bore kit that all match the appearance of the standard OE cylinder, at an affordable price. If you are a competent do-it-yourselfer or a motorcycle shop looking for quality standard and big bore cylinder kits, check out these new options from Cylinder Works for these Yamaha models. 

Included in each complete kit is a Vertex piston kit, top end gasket kit, and a new nickel plated standard or big bore Cylinder Works cylinder.   Standard bore cylinders are also available separately so builders can use the replacement piston of their choice.
