These parts are listed for 21 BETA models; the most common are BETA RR 250 (2013-2024), BETA XTRAINER 300 (2015-2025), BETA XTRAINER 250 (2018-2025), BETA RR 125 (2018-2024), BETA RR 300 (2013-2024) and BETA RR 350 (2013-2024).
The air filter keeps dust out of the engine, the main cause of top end wear off road. A foam filter is cleaned and re-oiled after every dusty ride; keeping a second filter ready to fit saves time between sessions.
