Frame

Let’s dive into the details of the RX 450 4T:

• Rear sub-frame and filter box: while the rear sub-frame’s geometry and the filter box remain the same, the structure has been suitably reinforced in a series of points that stiffen and strengthen it, maintaining lightness and ability to absorb stresses. Access to the filter remains on the left side of the bike, and is extremely easy and intuitive, as well as being tool free.
• Suspension: fork and single shock receive a new calibration that enhances the bike’s character, both in terms of handling and stability when increasing the pace. The result is an improvement of the features already highlighted by MXGP riders for this model – manoeuvrability and stability that instil confidence in every rider, regardless of their level.
• Battery: for safe first-shot ignitions, even in the most severe conditions of use, a new lithium battery has been mounted on RX MY25, with an amperage higher than the previous one, to always have the necessary starting power.
• Final ratio: to find the ideal compromise between speed and acceleration, the rear sprocket now has 51 teeth – one more than the previous model – to improve the engine response coming out of corners as well as allowing the engine to build RPM quicker.
• Graphics: while the superstructures recently introduced with the new tail remain unchanged, new, more sleek and aggressive graphics have been introduced, which do not lack character in highlighting the racing soul of the model.

RX 450

A few months ago, Beta’s project to expand the boundaries of RideAbility has officially landed in the new Motocross dimension, and the Tuscan company is already set to enhance its models day after day, and to keep its bikes simply at the top.

RX 450 was officially the first 4-Stroke Cross bike built by the manufacturer from Rignano sull’Arno, and, for fans, it was also the chance to ride a Made in Beta MX derived from the race prototype, which has now been racing for four years in the MXGP World Championship.
