Following the huge success of the electronic fuel injected BETA range of 4 stroke Enduro machines Beta have further refined their 4T range in 2019 with front & rear suspension & improved throttle control.


Beta’s engineers have worked directly with Synerject to provide an EFI system that has proven to be reliable, stable and extremely effective.

With its 42mm-diameter throttle body, the system ensures precise control of the fuel delivery under any condition, the air-fuel mixture is optimized at any altitude thanks to temperature and pressure sensors.

Riders of all levels will enjoy spontaneous and linear engine response.

In addition, thanks to the adoption of a stepper motor mounted on the throttle body, engine braking is significantly reduced and flame out stalls almost impossible. This insures a smooth and predictable power delivery that is synonymous with Beta.

The die-cast crankcase, forged pistons, Diamond like coatings on cam finger followers and oil rings, magnesium case covers, twin overhead camshafts and short stroke engines have a proven track record for reliability, light weight and tractor like torque and power.

The engines for MY19 meet the strict Euro4 emission regulations and feature a CAN connection for compatibility with generic diagnostic instruments.


The Beta RR range is renowned for their beautiful steering and suspension that is perfectly matched to the chassis.  The changes for 2019 push us even further ahead. 

The compact frame allows Beta to have the lowest seat height in the class and a bike that feels small and very well balanced under the rider allowing the rider to move around on the bike so much more.Many other new features have been introduced to further enhance handling as well as ease of maintenance.

70 years of motorcycle building experience has gone into ensuring the Beta RR Enduro bikes are engineered and built to ideally suit the seasoned pro along with enthusiast trail riders.

New ZF 48 mm forks are 100g lighter and arrive with a new adjustment system compression, rebound and spring preload adjusters on the upper fork cap make them adjustable while sitting on the bike without tools. Improved bottoming-out resistance (progression starts earlier in the stroke) gives greater stability. The new upper sleeve has improved anodizing that reduces friction and increases durability.

Fully re-designed ZF shock is a more compact 46 mm piston design and around 300g lighter. The new piston designed for more stable operation as oil temperature varies during riding and increased sensitivity for comfort and traction. The expansion tank is larger to work with the new piston the small upper base and reservoir has also been redesigned to be smaller. New spring is also lighter.

Beta is always receptive to feedback from its customers and when they were telling them they wanted their bikes to be even lighter and more agile - Beta listened.

Testing showed that an engine with a shorter stroke and a lower reciprocating mass led to a bike with these characteristics.

Further testing showed that this was possible with minimal loss of outright power and torque - and so in 2015 the new set of smaller capacity Beta engines were born - the RR390, RR430 and RR480.

The question “Why produce a 350, a 390, a 430 and a 480?” has been asked of Beta and one ride on each bikes quickly answers the question.

Although there is only 40 - 50cc increments between the three engines their characteristics are much different.


When the concept for a smaller capacity bike to compliment the rest of the BETA range was conceived the engineers at Beta didn't set out to necessarily build a 350cc motor. They set out to build a motor that provided the optimal combination of ideal torque and power and rideability. When the design and testing process was completed the engine that gave all of this happened to also be 350cc in capacity.

The world wide acclaim that the 350 has received is testament to the fact that the engineers at BETA got it right. The double overhead cam 4 titanium valved engine delivers a unique combination of tractable torque and top end horsepower that makes the bike very easy to ride at all levels. This allows the rider to stay in control at all times and therefore it does not tire the rider as bigger engined bikes can – you ride the bike, the bike doesn’t ride you.

Perhaps the biggest revelation however is just how light and nimble the smaller engine makes the bike feel. Although the RR350 shares the same frame and suspension as its bigger brothers the lower reciprocating mass and engine characteristics makes the bike feel much lighter. This combined with the bikes very low center of gravity and wide rider stance makes the 350 a single track weapon.

The RR350’s usable power and nimble handling characteristics mean that you can ride the RR350 better and faster for longer.


The extra capacity over the 350, different cams and ignition curves really let the RR390 lug. Whereas the 350 wants to spin up quickly the revs on the 390 build more slowly but the extra torque really puts every revolution of the motor to the ground.

You have the feeling the bike could climb a tree if it could get traction – nothing can stop it. Some have likened the power of the RR390 to the legendary power of the DR Z400 – just in a lighter, more agile and better handling frame. When the revs do build however the bike rockets along and takes hills and faster tracks in its stride.

Not being as powerful as the 430, you can be more ham fisted on the throttle with the RR390 and not find yourself in trouble but still have more than enough power to keep up with all your mates.

The great advantage of the RR390 is that whereas your mates on their more powerful bikes will be buggered at the end of the day, from fighting their beasts and trying to keep them out of the trees, you will still be as fresh as a daisy and ready for the next days ride.

Like the RR350, the smaller engine and chassis dynamics gives the bike a very light and flickable feel.

The RR390 is the ideal bike for the rider that doesn’t necessarily want to be the fastest rider on the trail but who wants to be riding as fast and in control at the end day as at the start and still be fit for work on Monday.



The Beta RR430 is the E2 weapon of the range.  Racer turned photo-journalist Adam Riemann is noted for his blunt assessments and he doesn’t hand out praise lightly but he was almost glowing when he exclaimed “Set up the suspension and you could win races on this bike!”, and that pretty much sums up where the RR430 sits in the Beta line up.

It’s a powerful bike and the engine, even in standard trim, has more than enough power for all but the fastest racers. Like all of the Beta engines however it does not come on in a huge hit but builds controllably so that it is fast and safe in a good trail riders hands.

Having power in reserve means that the average rider is using only a fraction of the engine’s potential and therefore it is not being thrashed at all which should lead to even greater reliability than the Betas have become renowned for.

Both the RR430 and RR480 drop two teeth off the rear sprocket from 50 to 48 which gives both of these bikes longer legs. This makes them ideal not just for the longer and faster fire trails but also for road sections or as a fast and nimble daily commuter bike.


The RR480 is the big brother of the RR range and it has all of the muscle to haul the biggest brothers amongst us or to cruise the wide open trails, the high country or the open road.

Like the RR430 the extra cc’s don’t make this an uncontrollable monster that can only be man handled by the strongest and fastest riders – the linear build of power makes the RR480 a gentle giant. The torque of the bigger capacity engine at low revs actually allows less skilled riders to idle over objects that riders on smaller capacity bikes would have to use refined throttle control to master.

Give this giant its head however and it eats anything in its path – it devourers the longest and steepest hills, gobbles up fire trails and roads and even gently grazes its way through single track.

The torque and power that the come with the larger capacity engine would allow the adventure rider or commuter to use a 14 tooth front or 45 tooth rear sprocket to give it higher gearing and make this bike a real tourer. Change the gearing and pick up a IMS long range fuel tank from the Beta accessories bin and head off to the Cape, to the middle of our great country or to the harder to get to wineries.
