The art of rideability in the MX world

Beta’s project to expand the horizons of Rideability enter a new dimension – Motocross! It is the first modern motocross bike built by the Italian manufacturer since the early 1980’s, represents the first chance in Europe for enthusiasts to ride a Beta Motocross bike, after its début in the MXGP World Championship three years ago.

We are talking about Beta RX 300 2T, the new frontier of Rideability in the World of MX.

What does Rideability mean for Beta? It means allowing every rider of a Beta bike to have a simultaneously easy-to-ride yet high-performance bike, a top-level performer, yet friendly, fun, and never too demanding. Today, for the first time, Beta is taking this concept to modern Motocross.
