Beta RR 250 [2018–2022]: A Two-Stroke Enduro Masterclass Revisited

Introduction

The Beta RR 250 isn’t just a motorcycle—it’s a declaration of intent. From 2018 to 2022, this Italian two-stroke enduro machine carved out a reputation as a fiercely capable off-roader that blends old-school adrenaline with modern refinements. After spending time thrashing it through muddy trails, rocky ascents, and tight forest single-track, it’s clear why this bike remains a cult favorite among hardcore enduro riders. Let’s dissect what makes this generation of the RR 250 tick—and why it might just be the perfect companion for your next off-road adventure.

Engine Performance: The Soul of a Two-Stroke

At the heart of the Beta RR 250 lies a 249 cc liquid-cooled single-cylinder two-stroke engine, producing a 13.2:1 compression ratio and fed by a Keihin PWK36 carburetor. While the world shifts toward fuel injection, this bike doubles down on carbureted simplicity—a choice that purists will applaud. The engine’s character is immediate: a raspy, unfiltered bark that translates into explosive mid-range punch. There’s no waiting for powerband “hit” here; torque arrives early and builds linearly, making it forgiving for novices yet thrilling for experts.

The 6-speed gearbox is slick and precise, with ratios tailored for technical terrain. First gear crawls up near-vertical climbs without stalling, while sixth gear holds its own on open fire roads. The electric starter (a godsend in muddy conditions) fires the engine to life instantly, and the liquid cooling system keeps temps in check even during slow, grueling sections.

Fuel consumption sits at 2.4 L/100 km (98 mpg), giving the 9.5-liter tank a realistic 150–180 km (93–112 mi) range—enough for a full day of trail riding. Purists will appreciate the lack of oil injection (premix only), which allows precise control over lubrication.

Chassis and Handling: Precision Meets Agility

Beta’s molybdenum steel double-cradle frame strikes a perfect balance between flex and rigidity. At 103.5–117 kg (228–257 lbs) dry, the RR 250 feels shockingly light when flicked through switchbacks or hopped over logs. The 48 mm Sachs USD front fork offers 290 mm (11.4 in) of travel, paired with a Sachs rear monoshock delivering 295–300 mm (11.6–11.8 in) of wheel travel. Setup is plush for trail riding but firms up predictably under aggressive input—no wallowing or bottoming out mid-jump.

Braking is handled by a 240 mm front disc and a matching rear rotor, both offering ample bite without the abruptness of race-oriented systems. The 21-inch front and 18-inch rear wheels (shod with knobby 90/90-21 and 140/80-18 tires) float over roots and rocks, while the 320 mm (12.6 in) ground clearance ensures skid plates rarely meet terra firma.

Ergonomics and Comfort: Built for the Fight

The RR 250’s 930 mm (36.6 in) seat height is accessible for riders around 175 cm (5’9”) and up, though shorter pilots might tip-toe at stops. Standing up reveals a narrow chassis that’s easy to grip with your knees, while the bars and pegs position you in an aggressive, attack-ready stance. The seat itself is thinly padded—comfort isn’t the priority here, but it’s bearable for multi-hour rides.

Fuel tank shaping is narrow, allowing easy weight shifts during cornering, and the overall width of 815 mm (32.1 in) lets you squeeze through tight trees without drama. At speed, the bike feels planted yet flickable, like a mountain bike with a jet engine.

Competition: How the Beta Stacks Up

KTM 250 XC-W

KTM’s two-stroke legend offers fuel injection (TPI) and slightly sharper suspension. However, the Beta counters with a smoother power delivery and a more robust frame. The RR 250 also undercuts the KTM in maintenance costs—no fuel injectors to fuss with.

Husqvarna TE 250

Sharing KTM’s DNA, the Husky prioritizes race-ready specs. Its linkage rear suspension outperforms the Beta’s progressive lever system on big hits, but the RR 250’s carbureted engine delivers a rawer, more engaging throttle response.

Yamaha YZ250X

The Yamaha is a budget-friendly alternative with legendary reliability. That said, it lacks the Beta’s electric starter and trail-friendly gearing, making it less versatile for technical enduro.

Verdict: The Beta RR 250 shines for riders who value simplicity, torque-rich power, and Italian handling flair. It’s not the most technologically advanced, but it’s arguably the most soulful.

Maintenance: Keeping the Beast Alive

Two-strokes are famously low-maintenance, and the RR 250 is no exception. Here’s how to keep yours in peak condition:

1. Spark Plugs: Stick with NGK BR8ECM or BR8ECMIX plugs. Check every 20 hours for fouling.
2. Air Filter: Clean after every ride with MOTOPARTS.store’s biodegradable filter cleaner. Our high-flow foam filters boost airflow for better throttle response.
3. Premix Ratio: Beta recommends 1.5–2% (60:1 to 50:1). Use synthetic oil for minimal smoke.
4. Coolant: Replace annually with ethylene glycol-based fluid. Our store stocks pre-mixed solutions.
5. Brake Fluid: Flush with DOT 4 yearly to prevent sponginess.
6. Chain & Sprockets: O-ring chains last longer, but for weight savings, try our X-ring kits.

Pro Tip: Grease suspension linkages every 30 hours to prevent wear. Our waterproof grease tubes are rider-favorites.
