RevTech® 88"
The original RevTech® 88 was launched more than eight years ago and 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 50% 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 20,000 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.

Crankcases

  • Cast from 356-T6 aluminum with wall thickness optimized for
    maximum strength
  • Advanced one-piece casting and machining techniques allow for near
    perfect case half alignment
  • Blind case bolts for cleaner appearance
  • Smooth crankcase deck to cylinder base profile for cleaner appearance
  • 7/16" cylinder studs proven in drag racing applications

Flywheels

  • Connecting rods and flywheels forged from 4340 chromemoly
    steel - the strongest material available for these applications
  • Larger straight 11/2"-diameter pressed-in crankpin using RevTech®'s
    proprietary extreme-duty military-grade steel

Oiling System

  • Late style external pump for improved efficiency and
    increased volume
  • Chrome cover

Cylinders

  • 3 5/8"-bore and 41/4"-stroke
  • Improved design with more fins overall, and longer fins in certain
    high-heat areas for better cooling
  • Steel liners are Perma-Locked into the outer aluminum castings
  • Cast pistons
  • O-ring base seals instead of gaskets

Heads

  • D-shaped exhaust ports for maximum flow and performance
  • Wider-spaced head bolt pattern for increased strength
  • O-ring head seals instead of gaskets for increased reliability

Carburetion

  • Mikuni HSR42
