Model: Sym Bonus 110
Part: Engine oil

To change the engine oil of the Sym Bonus 110, loosen the screw that secures the drain plug of the engine oil tank: this is located at the bottom of the bike, and once unscrewed, you can collect all the used oil in a suitably placed container. When all the oil has completely drained, top up through the cover located on the right side of the bike. Once the correct amount of oil has been added, close the cover, ensuring the bike operates correctly.

How do you replace the exhaust pipe of the Keeway RKF 125?

The operation of replacing the exhaust on the Keeway RKF is carried out by loosening the screws that fix the exhaust terminal at the lower support near the crank and at the mudguard of the motorcycle.

In this way, the old exhaust can be completely removed from its seat, replacing it with a new spare part and verifying that everything works.
