ADA Racing billet girdle head for the Kawasaki 1100 engine. All ADA Racing billet heads are made from 6061-T6 aluminum and CNC machined in-house for consistency and performance. The head shell is then clear anodized for durability protection against salt-water corrosion. This is the head shell only and includes orings that fit into the grooves in the head shell and brass fittings. Girdle design adds strength and rigidity to the cylinder to prevent cracking on ported cylinders. No machining of the cylinder is required for the girdle. Girdle kit and domes are NOT included. You will need to order the domes and girdle kit below under Related Products.
We offer 2 styles of domes, our standard dome and a 'race' dome. The race domes feature a wider squish band and less assembled squish clearance, and a decreased squish angle for a more aggressive design. Our standard domes are for up to an 82mm bore size and our race domes come in 82mm and 85mm sizes. Domes are shown below under Related Products.
