88”

RevTech 88" Engines The original RevTech 88 has been a tremendous success. But we didn’t rest on our laurels, we constantly improved it and now it’s better than ever. Our engineers and technicians have taken the knowledge accumulated while developing our new 110 and 100 and applied it to the 88. As a result, the RevTech 88 now makes about 30% more power than the motors from Milwaukee with comparable reliability. Like the bigger RevTech motors, the 88’s new cases are now cast in one piece. They are machined then precision cut with the halves kept as a pair. This new method ensures perfect alignment of the flywheels on the inside, with the added benefit of a better appearance on the outside. The improvements didn’t stop with the cases, the flywheels now feature straight 1 1/2" pressed-in crankpins using our proprietary extreme-duty military-grade steel, just like in our 110 and 100. The new flywheels are forged from 4340 chromemoly steel and the new connecting rods incorporated from the larger motors have proven indestructible. We will continue to improve our engines as we find new technology that proves itself in our vigorous testing. But know this, the RevTech 88 has the accumulated experience and knowledge behind it of the over 30,000 RevTech motors sold so far. We are proud of it, and confident that you will be too, as you enjoy each powerful, trouble- free mile. Replaces Evolution engines in Big Twin models 84-99
