ATHENA engine oil seal kit for BETA RR 250, RR 300 from 2013 to 2026

ATHENA offers this engine oil seal kit for BETA RR 250, RR 300 from 2013 to 2026. An oil seal (lip seal) is a rubber ring that seals around a rotating shaft. They are found on the crankshaft, gear shifter, water pump and output shaft.

Why replace the oil seals?

The benefits:

• Stop oil leaks around the shafts.
• On a 2-stroke, keep the crankcase sealed, which the engine needs to run properly.
• All the engine’s oil seals in one part number for a rebuild.

Why choose ATHENA?

Athena, original-equipment supplier to KTM and Ducati from Italy, laser-cuts its gaskets from materials designed for heat, oil and coolant.

When should you replace the oil seals on your BETA RR 250?

Seepage around the shaft, a dropping oil level or, on a two-stroke, an idle that creeps up on its own are warning signs. The seal is also replaced every time the cases are split.

Specifications and fitting tips
