SmartCarb For Beta 300 RR

$749.00$948.00

Build Your Own Beta Better!

This SC2 model SmartCarb replaces the stock 36mm Keihin PWK in Beta 300 RR, 300 RR Race Edition, and new 300 RR X-Pro dirt bikes, offering crisp, clean performance, excellent fuel efficiency, and incredible ease of use.

Choose the 36mm size if you spend more time at low revs riding trail, woods, singletrack, enduro, or tight/technical conditions where the bottom end or low speed is a priority. Choose the 38mm size if you spend most of your time in the upper throttle range, riding motocross, GNCC, supermoto, desert, or if you are snowbiking.

Betas using the factory oil injection system REQUIRE the MagVolt® Throttle Position Sensor. Betas with the oil injection system removed and 2020 and later Race Edition Betas with factory TPS do not require MagVolt® TPS. See Fitment Information tab below for more information.

Every SmartCarb ships pre-adjusted specifically for the bike for which it is ordered. Please provide information in the forms below about any engine/exhaust modifications, how you ride (riding style), and what fuel selection and oil premix ratio (if applicable) you use.
