The introduction of electronic oil injection headlines the updates to the 2016 Beta 300 RR two-stroke enduro. The system debuted on the 2015 Beta XTrainer and thanks to its success it is now on the 300 RR as well. The two-stroke oil is stored in a tank under the seat (easy to remove with just a push of a button) and holds 12 ounces of oil. The oil injection is managed by an ECU, which feeds a precise amount of oil into the system based on rpm and engine load, measured through the throttle position system (TPS). The ratio varies from 32:1 to 100:1, depending on the demands of the rider and the terrain. The oil injection system puts out a lot less tail pipe smoke and uses only as much oil as needed. To help keep the system idiot proof, two warning lights are built into the digital odometer. One notifies the rider if the oil tank level becomes too low, while the second red light warns of system failure. General ECU changes for 2016 were aimed increased performance in the upper rpms and to improve the already awesome bottom-end power and response.
