2008-2009 Buell XB12’s

Want more power out of your Buell?  We start by modifying the cylinder heads with our high velocity raised port upgrade.  We use our X-Braced piston to stabilize the piston and cylinder and raise the compression ratio to 10.5:1.  These two upgrades along with a performance ECM tune will enable your Buell to make between 100-106 horsepower
