To replace the piston of the Derbi Senda 50, you need to completely remove the engine from its housing by unscrewing the bolts that secure it. Once removed, you can loosen the bolts that secure the cylinder at the top of the engine block, pulling it out completely to access the piston inside. It must be removed from its connecting rod by loosening the retaining ring: once the old piston is removed, you can insert the new one, securing it and reassembling the cylinder.
