Beta 350

- 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. – 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. – 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. – New silencer protector. 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. – Completely redesigned tailpiece, greater strength to reduce breakage during off-road riding, all filter box components and related accessories are now housed inside it.- New air filter boot. – Filter mounting system, providing quicker and more accurate installation. – Improved fork design compared to the previous version, with a 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 a 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. – Larger capacity fuel tanks of 9.1 L for 4-strokes. Besides providing greater range, the new fuel tanks improve ergonomics and ease-of-movement in the seat. – Wider handlebars for greater control. – Side stand with a bigger foot.- New precision-cast footpegs that are better at shedding mud and teeth to increase boot grip. – New longer chain guide to suit new swingarm. – New brake pedal, more robust and with larger bearings.
