• Use only oil with RON 424 classification
NOTE
The ROTAX® Norm 424 (RON 424) is a BRP-Rotax internal
standard, which is only available on special request via the
ROTAX® authorized distributor and will not be disclosed to third
parties without prior consent.
• Due to the high stresses in the reduction gears, oils with gear
additives such as high performance motor cycle oils are
required.
• Because of the incorporated overload clutch, oils with friction
modifier additives are unsuitable as this could result in clutch
slippage during normal operation.
• Heavy duty 4-stroke motor cycle oils meet most of the re-
quirements. These oils are normally not mineral oils but semi-
or full synthetic oils.
• Oils primarily for Diesel engines have insufficient high tem-
perature properties and additives which favour clutch
slipping, and are generally unsuitable.
Use of multi-grade oils is recommended.
