Introducing the 2025 Beta RX 450 4T! The RX 450 was the first 4-stroke motocross bike built by the Italian, Rignano sull'Arno based manufacturer in 2024, and was the the first chance for riders to experience a bike directly derived from the race prototype, which has now been racing for four years in the MXGP World Championship.2025 sees the RX 450 receive exciting new updates that sharpens the model’s ability to perform on the the vast range of changes across the board for the MY2025 RX range, the project’s goal remained the same: equip the bikes with a frame, engine and components of the highest level, and bring a new frontier of RideAbility to the MX does RideAbility mean for Beta? It means designing and building bikes with RideAbility being the core value. Each Betamotor-branded motorbike is designed by the Florentine manufacturer to provide any rider with a motorcycle that is simultaneously easy to ride, and offer high performance. A product that’s able to extract the best from any rider, thanks to an engine-frame combination that is able to offer a fun ride, without a reason to fear the world championship level performance of the engine. For MY2025, the RX 450 achieves this MY2025 RX 450 sees the following changes:Rear sub-frame and air filter housing: while the rear sub-frame’s geometry and air filter housing remains unchanged, the structure has been suitably reinforced in a series of points that stiffen and strengthen it, maintaining lightness and its ability to absorb impacts. Access to the filter remains on the left side of the bike and is extremely easy and intuitive to use, as well as being tool free.Suspension: the KYB fork and single shock package receives a new calibration that enhances the bike’s character, both in terms of handling and its stability when increasing the pace. The result is an improvement in manoeuvrability and stability that instills confidence in every rider, regardless of their level.Battery: a new lithium battery has been mounted on the RX 450, with a higher amperage that delivers instant starting ratio: to find an ideal compromise between speed and acceleration, the rear now features a 51 tooth sprocket, one up from the previous model year, improving the response coming out of corners as well as allowing the engine to build RPM quicker.Graphics: while the plastics and new tail section remains unchanged, new, more sleek and aggressive graphics have been introduced, which further highlight the racing pedigree of this handlebar block: new silent blocks reduce vibrations and raise the handlebar by 5mm compared to the previous model, aiding in rider grip, control and performance.Footpegs: the range sees new, less bulky footpegs with an enhanced grip performance, providing greater control at all times.Swingarm: the rear wheel axle is reinforced and now 22mm in diameter (+2mm). This new component guarantees greater stiffness and torsional resistance, resulting in a bike that is precise in its handling, even in the toughest of maps: both the RX models are equiped with with two specific engine maps (wet/dry), while the RX 450 also has traction control (off/on) to manage the significant power in all conditions. The button to select the map and TC is located on the handlebar RX 450 is delivered with 4 different pulleys to customise the throttle response.
