ATHENA Engine Bearing for GAS GAS EC 250, EC 300 and APRILIA RX 125 1995-2015

On GAS GAS EC 250, EC 300 and APRILIA RX 125 from 1995 to 2015, the ATHENA MS300620160C4 engine bearing fits in place of the original part. In a motocross engine, the bearings spin fast and take hard knocks. Replacing a tired bearing at the right time saves the crankcase or the gearbox from damage.

Fitting tips

1. Heat the crankcase (around 100 to 120 °C) to remove the old bearing and fit the new one without force.
2. Only push on the race that is the tight fit: outer race in the crankcase, inner race on the shaft.
3. Check which way round it goes if the bearing has a shielded side.
4. Close up with new gaskets or a complete engine gasket kit.
