Sachs Front Fork

RR models arrive with the Gen4 Sachs front fork. This fork has been tested by the Beta engineering team many times over to improve the feel of the front end. We feel this is the best open cartridge fork on the market today

Pushbutton Seat

All Beta RR and RS models arrive with a push button quick release seat. This allows for easier access to the air filter, battery, and tool kit.

Electronic Fuel Injection

Beta’s exclusive EFI system is more than five years in the making. Unique to the system is the ability for dealers to be able to offer two different engine braking settings.

Quick-Change air filter system

Simply remove the seat with a button, pop off the side panel and the air filter is in broad daylight easy to change. More access than any other model, period!

Spark Arrestor

All Beta 4 strokes come standard with a USFS approved spark arrestor. This muffler is quiet and light without robbing horsepower.
