How to Change the Transmission Oil in a Beta 390 RRS

Model: Beta 390 Rrs
Part: Transmission fluid

Video tutorial

Is it time to change the transmission oil in your Beta? You're in the right place. It's great to perform maintenance on your bike yourself; in this guide, I will explain step by step how to do it correctly.

Place a container under the bike to collect the old oil. Unscrew the bolt closest to the rear wheel. Be careful as the oil will flow out quickly once it's free; be prepared.

Keep the bike upright to allow all the used oil to drain. Re-screw the bolt; the new lubricant goes into the reservoir on the right side of the bike.

You can check the level through the designated transparent window.
