Beta Motorcycles has launched its new 2020 RR enduro range which represents a new generation of enduro motorcycle from the Italian manufacturer.
The 2020 range includes eight different engine sizes: four two-stroke (125/200/250/300 cc) and four four-stroke (350/390/430/480 cc) engines that offer Beta customers an extremely wide selection of bikes.
The work of Beta’s design engineers, testers and the entire Research & Development team has been expanded and intensified. The engine team has introduced a completely new power unit to the four-stroke range, and the chassis team, with a frame that boasts completely redesigned geometry and rigidity.
New for 2020
Engine
Two-stroke – 125 cc
• New cylinder with modified exhaust port and diameters.
• New exhaust flange.
• New exhaust valve system and new boosters.
• New clutch cover with air purging system operated by the modified clutch mechanism; modified oil inlet cap position.
• New exhaust valve drive opens at a different rate to improve power delivery.
• New expansion chamber.
Two-stroke – 250/300 cc
• Now with a counter-balancer to reduce vibration by increasing inertia and improving the power delivery curve. The counter-balancer improves the power delivery throughout the rpm range.
• Cylinder head redesigned (250 cc only) to improve torque at low rpm.
4-stroke – 350/390/430/480 cc
• A complete redesign, with the aim of reducing the weight and bulk of moving parts, achieved by raising the clutch and moving the crankshaft back. Moving the center of gravity closer to the swingarm pivot makes for significantly better handling. An overall weight reduction of around 1 kg.
• A redesigned magnesium clutch cover redeveloped to improve the oil flow into the clutch assembly more efficiently.
• Magnesium flywheel cover, redesigned in line with the rest of the engine, now with a more functional and modern look.
• New water pump system that improves flow rate and therefore the efficiency of the cooling system’s ability to transfer heat, keeping average temperatures lower, improving performance, and providing a more simplified cooling hose system.
• Cylinder and head redesigned matched with the updated cooling system to lower engine temperatures.
• Oil circuit redesigned to provide better heat transfer between oil and water in the front section of the crankcase in order to keep the oil temperature lower.
• Clutch with redesigned discs in a new material to ensure smoother and more modular gear shifting.
• Redesigned gearing, now shorter and lighter.
• New gearshift mechanism with lighter cam to improve shifting.
• Gearshift lever redesigned in line with the new engine and frame layout.
• Addition of a neutral sensor.
• Updated EFI mapping.
Chassis
• New frame with redesigned geometry and rigidity for increased agility and stability. Weight is reduced and reliability boosted with the use of precision-cast components, while comfort is improved, and vibration reduced thanks to new head bolts. The frame is also narrower at the base which improves handling over difficult sections and typical off-road tracks.
• Modified swingarm, now longer for the 4-stroke range and the 200 cc 2-stroke model, for better stability and traction.
• Completely redesigned tailpiece, greater strength to reduce breakage during off road riding, all filter box components and related accessories are now housed inside it (electrical components and oil reservoir for 2-strokes).
• New air filter boot.
• New filter mounting system, providing quicker and more accurate installation.
• Improved fork design compared to previous version, with new inner cartridge to lower the centre of gravity providing the perfect level of plushness while also improving the action of square-edge impacts. Internal valving has been updated to work in-line with the new frame design.
• New rear shock absorber with new top-out system, now a spring to improve grip and contact with the ground during hard braking.
• New longer shock bumper with more progressive compression. This ensures good protection of the buffer and improves bottoming resistance.
• New valving, to work in-line with the new frame.
• Improved cooling system with water hoses placed inside the frame and more efficient radiators. This improves heat transfer and allows engines to operate at lower temperatures even in the most extreme conditions.
• Larger capacity fuel tanks, of 9.1 L for 4-strokes and 9.5 L for 2- strokes. Besides providing greater range, the new fuel tanks improve ergonomics and ease-of-movement in the seat.
• Wider handlebars for greater control.
• Exhaust with new layout in line with the bike’s new rear section.
• Side stand with bigger foot.
• New precision-cast foot pegs that are better at shedding mud and teeth to increase boot grip.
• New chain guide, longer to suit new swingarm.
• New brake pedal, more robust and with larger bearings.
• Shorter 430/480 cc gearing compared to previous models.
Beta Australia has confirmed the new range will be available in Australia from September. Pricing is still to be announced.
