-Die-cast clutch and ignition covers in magnesium: ensuring very low weight and optimal surface finish. It was possible to also adopt this solution for the inner clutch cover thanks to the isolation of the water pump from this element.
-V-force4 reed valve assembly: the presence of the stoppers ensures high reliability without compromising performance. Provides stronger low-end power output.
-Pre-mix: to keep the weight of the bike low.
-6-speed dog-box transmission: specially developed for this engine with gears made by mechanical machining of blanks, forged so as to provide mechanical strength and reliability while still maintaining very light and compact gearbox.
-Clutch: multi-disc in oil bath with reverse opening, unlike the larger RR's, this clutch actuator is integrated in the outer cover. This is a system designed for maximum lightness and compactness of the engine which, thanks to its low positioning, ensures the reduced size of the power unit and a significant centralization of weight.
-Electric starter-ready: Beta has designed the 125 engine to accept, as an accessory an electric start system for those wanting a push button start.
Chassis
The chassis derives partly from the 250/300 RR but was developed specifically to optimize the behavior of the engine-frame combination. The frame, in chrome molybdenum with double cradle split above the exhaust port, has been redesigned for a small engine, revising its principal dimensions and ensuring an optimal positioning of the engine.This solution has allowed particular characteristics of the RR family to be further enhanced, such as its great maneuverability and ridability - even more noticeable due to the low weight of the motorcycle - as well as stability.
Among the many innovations adopted on this model are:
-Geometry of the new upper engine head stay: various solutions were researched and developed before the final one that made it possible to reduce the vibrations generated by the engine while maintaining significant engine-frame system stiffness.
-Sachs Suspension: derived from the rest of the RR range but with its own settings. At the front there is an open-cartridge fork of 48 mm diameter.
-Exhaust system: in order to optimize the 2-stroke engine's torque and power curves, the Beta R&D Department has developed a special system dedicated to Enduro use.
-Filter box sleeve: designed for the 125 cc engine, it improves the flow across the range of operation, from low revs upwards.
-Engine guard: made from polyamide to combine strength and lightness, it provides excellent shielding against the ingress of mud between the engine and the guard.
-Fuel tank: a slightly smaller tank has been adopted to improve ergonomics on board the bike while maintaining sufficient fuel mileage.
-Cooling system: designed especially for this bike, it has new hoses and radiators with specially shaped reservoirs to fit the small size of the motorcycle.
-Nissin braking system: extremely powerful and configurable, the same as on the rest of the Enduro range.
-Colors and graphics: the same as the rest of the RR my 2018 range.
Available at Beta USA dealers beginning in February.
