2021 250/300 RR & Race Ed. 2-Stroke![]() The primary difference between the 2021 Beta 125 RR and the 200 RR is the displacement of the motor. Beta increases both the bore and stroke of the 125 to get it to a 200. That means more power everywhere for the 200, rather than focusing exclusively on more torque or more horsepower. The 200 and 125 RRs both feature oil injection, electric start, and an adjustable power valve. By adjusting the power valve, the rider can tailor throttle response to conditions and preferences. 2021 250/300 RR & Race Ed. 2-Stroke by Category |
