1999-2017 Yamaha YZ250 Cylinder Sleeve Liner
LA Sleeves are used to re-line your cylinder by machining the bore to the dimensions of the sleeve so that it can be installed to the cylinder. Once installed the sleeve can be bored to suit oversized pistons, which can work out cheaper than Nikasil plating in the long run and give the cylinder a longer life.
The cylinder sleeve is made from chrome-moly alloy. Outside diameter precision centerless ground. Ports cut to precision dimensions and shapes for ease of installation and port match up.
