Revolution Performance Sportster, XB and XR1200 Velocity Cylinder Head Package

(For 883cc and 1250cc Sportster, XB and XR1200 style motorcycles)

$929.95

The Revolution Performance Velocity CNC Cylinder Head Package was developed on the flow bench, dyno and street to increase power and torque on 883 cc and 1250 cc engines. These heads flow much better than stock, with our focus on port velocity we have created heads for better overall power and ride-ability. The ports are machined with laser accuracy on our state of the art Centroid A560 5-Axis CNC Machine Center and then hand blended. We install new guides and then perform a valve job using our Newen BB Contour Turning Center. The combustion chamber is cross buffed, and the gasket surface machined for optimal combustion chamber volume. We then assemble heads with 1.720” intake valves, 1.480" exhaust valves and .650 max lift springs. The heads are shipped ready to install.
