Collectively, the refinements made to Beta’s RR vary over the previous three years have advanced these machines into very good, world-class enduro weapons. A lot in order that, in line with Aussie enduro icon, Geoff Ballard, the 2023 RR390 is among the best-performing enduro bikes he’s ever ridden straight out of the crate.

However as anybody who’s spent their hard-earned on a bike will let you know, a motorcycle’s efficiency is simply half the equation; possibly much less. The standard of the possession expertise additionally has rather a lot to do with what the machine is wish to ‘reside’ with over the longer haul – all the things from fastener commonality to ease of upkeep to how sturdy its elements are (or aren’t).

Now that we’ve racked up 20 hours’ run-time on our 2023 Beta RR390 undertaking bike, we’ve acquired a fairly good deal with on what it’s wish to reside with (and play aboard). So, welcome to our two-part sequence of insights into the Italian model’s biggest-selling four-stroke.

In Half 1, we shone a highlight on the Beta RR390’s greatest character traits and standout elements, and those who may nonetheless do with somewhat work. And now, for Half 2, we spotlight the elements that house owners ought to preserve their eye on, plus provide a number of suggestions and methods in terms of sustaining your Beta RR…


FASTENERS: Checking and re-tensioning key bolts (rear sprocket, triple clamps, fork leg pinch bolts, and so forth) and spoke nipples is routine upkeep for each new motorbike, however simply ensure you take the gas tank off your Beta and examine the engine mount bolts as effectively. Devoid of any Loctite, our RR390’s engine hanger bolt had come unfastened after a number of hours’ use. Additionally, we wanted to place a washer below the top of the bolt used to safe the earth wire. With out shimming it, the bolt is barely too lengthy and bottoms out earlier than its head is absolutely seated.

ELECTRICAL SYSTEM: Converse to the mechanics in any impartial workshop they usually’ll let you know that Beta’s late-model RR fashions boast a super-robust engine, transmission and clutch, however can have a number of gremlins of their electrical system (predominantly, the fuses and wiring loom) if the Beta seller hasn’t coated these electrical elements in dielectric grease as a part of their pre-delivery course of. Fortunately, a larger majority of Beta sellers are onto this, however it’s value casting a watch over your RR’s wiring, fuses and junctions infrequently.

SPEEDO WIRES: Simply examine that the speedo wiring and plug is mounted in a approach that doesn’t pull too tight when the fork is absolutely compressed. By the point customers get the bike, their Beta seller ought to have already carried out this easy repair (which entails unplugging the speedo from the mounting plate and relocating it larger up close to the higher fork brace).

FUEL LINE CLAMPS: When you’ve eliminated the gas tank a number of instances (and are a bit ham-fisted), the crush-clamp on the gas line (close to the place it comes out of the rear of the gas tank) can spring a leak. Quite than exchange the clamp, we merely strengthened the gas line with some safety-wire both aspect of it, and it labored a deal with. The choice is to purchase a number of back-up gas line clamps – although they’re these single-use jobs, which require a nice decide to unlock and particular pliers to correctly match.

REAR TYRE CLEARANCE: When you’re working a 120-width rear tyre, its clearance with the muffler will probably be very tight (particularly for those who are inclined to run decrease pressures, which permits the tyre’s sidewalls to balloon below load). To make sure it doesn’t rub when the rear suspension is absolutely compressed, merely shim the muffler out a tad by inserting a barely wider alloy spacer on the rear mount. It’s additionally doable to create added clearance by machining 2mm off the mid-mount spacer.

FUEL LINE COUPLING: The short coupling on the gas line can get somewhat sticky and awkward – each to separate and to reconnected. Be sure you hear it click on again into place as a result of, even when it seems to be correctly related, it might not be (during which case, the bike gained’t run). A fast squirt of silicon spray to the coupling every so often will assist make it extra obedient.

HANDLEBAR SET-UP: While you arrange your entrance brake, throttle housing and handguard perches on the RHS of the bars, simply examine that the wires coming from the electrical begin are routed in order that they’re not simple pinched by the bolt-heads within the occasion of a crash.

SEAT-MOUNT GROMMET: The round-shaped rubber grommet below the seat tends to fall out fairly simply while you take away the seat. So simply double-check it’s in place earlier than re-fitting the seat. Higher nonetheless, whack a dab of silicon on it to maintain it in place.

IDLE ADJUSTMENT: As per the in-your-face instruction on p37 of the bike’s house owners handbook (“DO NOT TOUCH THE IDLE ADJUSTER SCREW FOR ANY REASON”), don’t contact your idle adjuster screw as a result of it’ll throw the mapping out of whack. When you do alter the idle, it’s not the top of the world. As defined on this video, the repair is a fast and straightforward job to your Beta seller, who’ll use diagnostic software program and a particular Beta interface software to reset the bike’s mapping to the really useful “+200” map. This will increase idle velocity (from 1800 to 2000rpm) and resets the TPS and stepper motor within the throttle physique. All of which makes you surprise why Beta doesn’t simply take away the idle adjuster within the throttle physique altogether!?


MINIMAL TOOLS REQUIRED: Fastener commonality is so good, you’ll be able to just about strip the bike with an 8, 10 and 13mm T-bar, and a few Torx bits.

DIGITAL DIY: The bike’s house owners handbook is complete and straightforward to observe. Sadly, it solely is available in digital type, which implies you find yourself wiping your greasy mitts over your telephone or laptop computer’s trackpad if referring to it whereas engaged on the bike.

OIL CHANGES: You’ve acquired to like the truth that Beta’s four-stroke engines now have separate engine and transmission oil. Positive, it takes somewhat longer to empty and re-fill each oil compartments, however by quarantining your engine from all of the contaminants created by your clutch, you’re doing it an enormous, durability-friendly favour. Simply keep in mind that, in contrast to most different bikes, it’s worthwhile to examine the engine oil stage within the inspection window with the engine idling, not after switching it off.

AIR FILTRATION: Air filter checks and adjustments are a cinch. Entry to the airbox is a straightforward, software free affair. As soon as in there, the design (which borrows closely from KTM’s ingenious air filter cage-fastening design) makes filter alternative just about idiot-proof.

FUEL TANK REMOVAL: Eradicating the gas tank solely requires three bolts, however earlier than you’ll be able to relaxation the factor on the bench subsequent to the bike, there’s a few further connectors to take away first. Along with the gas line and electrics working to the gas pump, you additionally must disconnect the wires for the gas reserve sensor and the dual-map/TC selector swap (which mounts to the entrance of the tank, not up on the bars). When reinstalling the tank, ensure you tuck this selector swap wiring up behind the wiring loom (towards the body) to stop it chaffing.

HOUR METER FUNCTIONALITY: Along with the (non-adjustable) hour meter constructed into the bike’s digi speedo, there’s additionally an Hour Meter A and Hour Meter B operate, each of which might be manually zeroed. And this makes it approach simpler to maintain observe of issues in terms of scheduled upkeep.

IMPRESSIVE QC: The standard of end throughout your entire machine is superb, with thought evidently put into each part’s design. Rubber grommets are judiciously used to cut back vibration or chaffing. Alloy collars guarantee fastening bolts don’t pull by means of plastics. Plus, gas strains and electrical cables and breather hoses are all cleverly routed to minimise put on over time.
