The engine team has introduced a completely new power unit to the four-stroke range, and the chassis team have developed a frame that boasts completely redesigned geometry and rigidity. The design aspect is also deserving of a mention, as the superstructure, tailpiece, seat and a myriad of other details are all brand-new.

All this to bring together optimised aesthetics and ergonomics. The 2020 range includes eight different engine sizes – four two-stroke models in 125/200/250/300cc and four four-stroke models in 350/390/430/480cc engines that offer a wide selection of bikes with which to take on the next adventure.

2020 Beta RR Chassis Updates

A new frame with redesigned geometry and rigidity for increased agility and stability is featured for 2020 models, while weight is reduced and reliability boosted with the use of precision-cast components. Comfort is also improved, and vibration reduced thanks to new head bolts, while the frame is also narrower at the base which improves handling over difficult sections and typical off-road tracks.

The 2020 Beta RR enduro models feature a redesigned frame

A modified swingarm is now longer for the four-stroke range and the 200cc two-stroke model, for better stability and traction. A completely redesigned tailpiece is also featured, with greater strength to reduce breakage during off road riding, and all filter-box components and related accessories are now housed inside it (electrical components and oil reservoir for two-stroke models).

There’s also a new air filter boot and filter mounting system, providing quicker and more accurate installation.

Fork design has also been improved compared to previous versions, with new inner cartridge to lower the centre of gravity providing the ideal 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.

Forks are also improved, with a new inner cartridge and updated valving. A new shock is also included with top-out system, and new valving.

This is joined by a new rear shock absorber with new top-out system, now a spring to improve grip and contact with the ground during hard braking. The new longer shock bumper with more progressive compression, ensures good protection of the buffer and improves bottoming resistance, alongside new valving, to work in-line with the new frame.

An improved cooling system with water hoses placed inside the frame is also included alongside 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 are also fitted, of 9.1L for four-strokes and 9.5L for two-strokes. Besides providing greater range, the new fuel tanks improve ergonomics and ease-of-movement in the seat.

There’s also wider handlebars for greater control, with the exhaust in a new layout, in line with the bike’s new rear section. The side stand also has a bigger foot for more security on soft ground and uneven surfaces.

Footpegs are also optimised for better grip and shedding mud

New precision-cast foot pegs are also better at shedding mud and teeth increase boot grip, with a new brake pedal, more robust and with larger bearings.

A new chain guide is fitted to the longer new swingarms and shorter 430/480cc gearing is featured compared to previous models.

2020 Beta RR Design Updates

A completely new superstructure is featured in 2020 including front cowl, front and rear fenders, ducts and fairings, and improves ergonomics and the operation of all related parts, while retaining the Italian design Beta is known for.

A front fender with variable thickness geometry which reduces weight and increases rigidity, with the new tailpiece and attachments made in techno-polymer.

There’s also a new handlebar protector, and redesigned seat to be more comfortable when moving about on the bike. Other new features include the license plate bracket with integrated handles, silencer protector (excluding the 125cc), digital instruments and instrument panel, and rear light. There’s also a redesigned skid plate, along with new frame protectors.

2020 Beta RR Two-Stroke Engine Updates

The two-stroke 125cc model features a new cylinder with modified exhaust port and diameters, as well as new exhaust flange, exhaust valve system and new boosters. A new clutch cover with air purging system is operated by the modified clutch mechanism; with modified oil inlet cap position.

The new exhaust valve drive opens at a different rate to improve power delivery and there’s a new expansion chamber, while these modifications to the 125 RR (derived straight from the 2019 Racing model) have allowed Beta to achieve added torque at low rpm while greater power at the high revs, for increased performance across the entire power curve, in a bike that is easier to ride.

A counter-balancer is also featured on the 2020 RR 250/300cc 2T models

The two-stroke 250/300cc models now come fitted 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, and a cylinder head redesign on the 250cc model only improves torque at low rpm.

2020 Beta RR Four-Stroke Engine Updates

The four-stroke 350/390/430/480cc range features 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 also makes for significantly better handling, with an overall weight reduction of around 1kg.

A redesigned magnesium clutch cover was developed to improve the oil flow into the clutch assembly more efficiently, with a magnesium flywheel cover redesigned in line with the rest of the engine, now with a more functional and modern look.

A new water pump system improves flow rate and 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.

The cylinder and head were redesigned to match with the updated cooling system to lower engine temperatures, with the oil circuits were 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.

The clutch with also redesigned, with discs in a new material to ensure smoother and more modular gear shifting, alongside revised gearing, now shorter and lighter. A new gearshift mechanism with lighter cam improves shifting, and the gearshift lever was redesigned to suit the new engine and frame layout. There’s also a neutral sensor, alongside updated EFI mapping.
