800R Performance

800 R PRODUCTS-2007-2015

We've been developing this 800R Engine since 2005 before production began and have more time developing this engine than anyone.


Rotax missed the balance on this engine by a mile which is the reason your clutch parts wear out and your hands fall asleep to vibrations created by this design flaw. We have the cure for this issue with our balance option which will make this engine smooth and free up hidden power robbed by this issue, includes, balancing parts, pin centers, weld pins if requested, assembling crank and case assembly, grease bearings with OEM Rotax Iso Flex grease,

$900.00 Plus parts (bearings, seals if needed)
