To replace the fork seal on a Derbi Senda, unscrew the bolts that secure the fork to its housing: these are located at the bottom of the fork and at the top, just below the handlebars. Once all the bolts are loosened, you can completely detach the fork and leverage inside its housing to remove the seal present inside; after removing the old seal, insert the new one and refit the fork to its position.
