2019 Beta RR range unveiled | News
Beta Motorcycles has unveiled its 2019 RR enduro range boasting more models than previous years including the introduction of a brand-new bike.
The Tuscan bike builder introduced a new 200cc two-stroke. Following the recent introduction of the 125 cc, it completes the product range, which now features eight different models.
Given the engine size and low weight, the newly arrived RR 200 2T has inherited the chassis set-up of the 125. More specifically, the frame, in chrome molybdenum with double cradle split above the exhaust port, has been designed for small engine displacements. It features revised main dimensions and ensures optimal engine positioning. The chassis, an offshoot of its smaller 125cc sister – is characterized by a special layout that aims to optimize weight distribution and engine dynamics.
NEW FOR 2019
• New engine control unit (ECU): claimed to produce a more powerful spark at high revs, improving combustion and engine performance.
• Clutch actuator with wider diameter: designed to give the clutch lever a softer, more responsive feel.
• New BPV exhaust valve opening adjustment (on 300 cc only): allows extremely linear power delivery, creating a high-performance engine that is easy to use under extreme conditions.
• Powervalve spring kit (on 300 cc only): supplied with the bike to extend the bike’s scope for personalization according to the rider’s needs. Thanks to springs with a spring rate lower than the standard ones, performance is better at mid-high revs, giving fuller, more decisive power delivery.
• Stiffer clutch cover (on 125 cc only): improves operation and produces a more precise bite-release action.
• New expansion chamber (on 250/300cc only): ensures increased performance throughout the rev range.
• New throttle control: designed by Domino exclusively for Beta for improved engine response to minimal throttle twists.
• New mapping for all engine sizes.
• Clutch actuator with wider diameter: claimed to give the clutch lever a softer, more responsive feel.
• New ZF (48 mm) fork with new adjustment system: allows positioning of the compression, rebound and spring preload adjusters on the upper fork cap; they can be reached while sitting on the bike and do not require tools. The fork also benefits from a new packing system and a slider with special anodizing that reduces friction and increases durability.
• New fork shoes (yoke): stiffer and lighter.
• New fork guards.
• Fully redesigned ZF shock: with more compact 46 mm piston, about 300g lighter. The new piston has been designed to ensure more stable operation as the oil temperature varies and increased sensitivity to enhance comfort and traction. The small upper base and reservoir have also been redesigned to rationalize the system and minimize weight and bulk. New spring is also lighter.
• New graphics and colors.
NEW Beta RR 200
RR 200 cc 2-stroke
As already mentioned, the introduction of the 200cc engine has broadened the RR my 2019 range.
• Double piston rings (62 mm): component designed to ensure high rigidity and reliability; the choice of double rings provides a better seal at the low and medium revs of Enduro riding.
• Beta progressive valve: made-in-Beta system characterized by a special relationship between the opening of the main flap and that of the side boosters. The delayed opening of the boosters enables excellent performance progression throughout the engine’s rpm range.
• Crankshaft with polyamide inserts: favors lightness and ensures optimum filling of the crankcase, boosting performance and reliability.
• Cylinder: has an exhaust flange system as on the bigger engines, enabling better control of frontal piston-flap-cylinder play. By keeping this value to a minimum, it is possible to achieve a significant low-rev performance boost by reducing gas leakage.
• Aluminum demountable cylinder head dome: rigid and lightweight solution made possible by shifting the engine mount on to the cylinder. The geometry of the combustion chamber is designed to ensure a high-efficiency thermodynamic cycle and obtain the best compromise between responsiveness at low-to-medium revs and during spurts. It also facilitates fine tuning and replacement of the combustion chamber.
• Die-cast crankcase in aluminum alloy: the casing geometries were designed according to an innovative layout in terms of the relative position of components and with a view to maximum weight reduction without compromising structural strength. Considerable attention was focused on the main bearing area to ensure correct wall rigidity in order to withstand the stresses transmitted by the crankshaft.
• Die-cast crankcase covers in magnesium alloy: ensure very low weight and optimal surface finish. It also proved possible to adopt this solution for the inner clutch cover thanks to isolation of the water pump from this element.
• Vforce4 reed valve packet: the stoppers ensure high reliability without compromising performance.
• 6-speed dog-box transmission: specially developed for small Beta engines with gears made from forged blanks to provide mechanical strength and reliability while still keeping size and weight extremely low.
• Clutch: multi-disc in oil bath with reverse opening, actuator integrated into the outer cover. This is a system designed for maximum engine lightness and compactness. Thanks to low-slung positioning, it ensures reduction of power unit size and a significant centralization of weight, crucial for good chassis dynamics.
• Exhaust system: to optimize the 2-stroke engine’s torque and power curves, the Beta R&D Department has developed a special system dedicated to this engine size.
• Electric start: perfect start-up convenience whatever the situation.
• Automatic oil injection: eliminates the need for a fuel-oil premix.
• Geometry of the new upper coupling points: various solutions were investigated and developed before reaching a final one that has allowed a reduction in engine-generated vibration while maintaining good engine-frame system stiffness.
• New ZF (48 mm) fork with new adjustment system: allows positioning of the compression, rebound and spring preload adjusters on the upper fork cap; they can be reached while sitting on the bike and do not require tools. The fork also benefits from a new packing system which ensures greater stability and a slider with special anodizing that reduces friction and increases durability.
• New fork shoes (yoke): stiffer and lighter.
•New fork guards: designed together with the shoe to combine practicality and design.
• Fully redesigned ZF shock with more compact ø 46 mm piston. The new piston has been designed to ensure more stable operation as the oil temperature varies and increased sensitivity to enhance comfort and traction. The small upper base and reservoir have also been redesigned to rationalize the system and minimize weight and bulk. New spring is also lighter.
• Filter box air boot: designed for this engine type, it improves flow across the entire rev range, even at low revs.
• Engine guard: made from tough yet light polyamide, it features excellent shielding to stop mud getting between the engine and the guard itself.
• Fuel tank: compared to larger models, a slightly smaller tank has been adopted to improve on-board ergonomics while maintaining good fuel autonomy.
• Cooling system: specifically designed for this bike, features new pipes 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.
