The engine components are machined on state-of-the-art CNC equiptment for guaranteed dimensional accuracy and repeatability. All of the engines are dynamically balanced using propritory methods to provide the smoothest running engines on the market. With their new high-flow cylinder heads, these are now the most powerful engines on the market as well. The Ultima El Bruto Engines are available with show polished, black or natural finishes. The 100, 107, and 113 cubic inch motors come with a 12 month or 12,000 mile manufacturer's warranty. The 120 and 127 cubic inch motors come with a 6 month or 6,000 mile warranty.
