2027 Beta 250RX-F

Built for Any Moto, Ready for Every Gate.   The 2027 RX 250F 4-Stroke is all-new from the ground up. The engine is a dual overhead cam with a piston design that came straight from F1 technology. Featuring electric start and dual-injector fuel injection, the power output is extremely competitive straight out of the box. This new power plant was designed and manufactured in Florence, Italy, in-house, ensuring the Italian passion is alive and well. The dual-injector electronic fuel injection system utilizes a 46mm tapered throttle body to deliver optimal air-fuel dispersion across the entire rev range, maximizing low-end throttle response while sustaining maximum power at high RPMs.". This new component comes straight from the AMA Supercross team as well as the MXGP team in Europe. It provides increased air speed and volume to the motor which enhances the low-to-midrange power overall while providing a quicker throttle response across the board.   The RX 250F 4-Stroke benefits from a frame designed to meet the specific needs of a 250F size and feel. Compared to the central engine connection solution used on its big brother model, the design features side-mounted engine head mounts: an engineering choice that increases torsional stiffness while maintaining greater vertical flexibility. The result is a new balance between cornering precision and suspension performance, with significant benefits in traction and stability. Completing the entire package is the tried-and-true suspension system, KYB front fork and rear shock, valved with specific settings developed to suit the lighter weight of the rider and bike. KYB suspension is the industry leader in Supercross and Motocross and was the only choice for the new RX 250F 4-Stroke. With its all-new, high-output engine, precision-tuned chassis, and industry-leading suspension, the 2027 RX 250F 4-Stroke isn't just built to compete—it's engineered to set a new benchmark for what a 250cc four-stroke can do.   ENGINE SPECIFICATION ENGINE TYPE Single cylinder, 4 –stroke, liquid cooled, 4-valve (Titanium intake and exhaust), electric start BORE 78mm STROKE 52.3mm DISPLACEMENT 249.3cc COMPRESSION RATIO 14.4:1 VALVE TRAIN DOHC finger followers / 4 valve Titanium IGNITION Mitsuba SPARK PLUG NGK LMAR9AI-8 LUBRICATION Twin Oil Pumps w/ Cartridge Filter & Separate Compartments For Engine & Transmission CLUTCH Wet Diaphragm Style TRANSMISSION 5 Speed FUEL SYSTEM EFI w/46 mm tapered throttle body and dual injectors ELECTRONICS Launch Control, Traction Control, & Quick Shift FINAL DRIVE Non-O-ring chain CHASSIS SPECIFICATION FRAME Molybdenum steel / Double Cradle w/ quick air filter access WHEELBASE 58.0" SEAT HEIGHT 37.2" GROUND CLEARANCE 13.4" FOOTREST HEIGHT 16.6" DRY WEIGHT 222.7 lbs FUEL TANK CAPACITY 1.85 US Gallons FRONT SUSPENSION 48 mm KYB AOS closed cartridge fork, adjustable compression & rebound REAR SUSPENSION KYB 50mm body with linkage, adjustable rebound, and high/low speed on compression adjustment FRONT WHEEL TRAVEL 12" REAR WHEEL TRAVEL 11.8" FRONT BRAKE 260 mm floating rotor REAR BRAKE 240 mm rotor FRONT/REAR RIM 21" (Front) 19" (Rear) FRONT/REAR TIRE Dunlop Geomax MX 34 DOWNLOADS TECH SPECS *Specifications subject to change without notice.
