Beta Evo 300 2T [2012-2016] Review: Mastering the Art of Balance

Introduction

The Beta Evo 300 2T represents the pinnacle of trial motorcycle engineering from Beta’s golden era of lightweight, competition-focused machines. Produced between 2012 and 2016, this two-stroke trial bike carved its reputation as a nimble, forgiving, yet fiercely capable machine for riders who demand precision in technical terrain. While modern bikes chase complexity, the Evo 300 2T reminds us that simplicity, paired with thoughtful design, creates a timeless riding experience. Let’s dissect why this Italian stallion remains a favorite among trial enthusiasts and weekend warriors alike.

Design & Ergonomics: A Purpose-Built Contender

Beta’s design philosophy for the Evo 300 2T screams function over flair, though its red/white/black livery gives it a race-ready aesthetic. The single-wave hydroformed aluminum frame isn’t just eye candy—it’s the backbone of a machine that tips the scales at a featherlight 67 kg (147.7 lbs). For comparison, that’s lighter than most full-suspension mountain bikes.

The 660 mm (26-inch) seat height sits you in a natural standing position, critical for trial riding where 90% of your time is spent off the saddle. Narrow bodywork (just 435 mm wide at the pegs) lets you grip the bike with your knees effortlessly, while the 2.8L fuel tank is discreetly tucked under the seat to maintain a low center of gravity.

During our test ride, the first thing you notice is how the Evo disappears beneath you. There’s no fighting for balance—just you and the terrain. The Michelin trial tires (2.75-21 front, 4.00-18 rear) bite into loose soil and rocks with a confidence that makes steep, muddy inclines feel like mild annoyances.

Engine & Performance: Two-Stroke Simplicity at Its Finest

At the heart of the Evo 300 2T lies a 296.4cc liquid-cooled single-cylinder engine, fed by a Keihin PWK 28mm carburetor. Forget fuel injection—this is old-school two-stroke charm with a modern twist. The lamellar induction system ensures crisp throttle response, delivering power in a smooth, linear curve rather than the abrupt "hit" older two-strokes are known for.

With a 10.2:1 compression ratio, the engine thrives on low-RPM torque. On technical climbs, it’s possible to crawl at walking speeds without stalling, yet a quick twist unleashes enough power to loft the front wheel over waist-high obstacles. The 6-speed gearbox is butter-smooth, though trial purists will spend 95% of their time in 1st or 2nd gear.

The wet multi-disc clutch deserves special praise. Pull force is surprisingly light—about 30% lighter than GasGas equivalents of the era—making feathering effortless during rock gardens or pivot turns. After three hours of riding, there’s no arm pump, just a slight ache from grinning too hard.

Chassis & Handling: Where Physics Takes a Backseat

Beta’s hydroformed aluminum frame pairs with a 165 mm (6.5") front fork and 180 mm (7.1") rear monoshock to create a suspension setup that’s plush yet communicative. Unlike MX bikes, trial suspension prioritizes slow-speed compliance over big jumps. Over jagged rocks, the Evo floats like a dirt-cloud, absorbing impacts without kicking back.

Braking is handled by a 4-piston front caliper and 2-piston rear, both biting single discs. Modulating the front brake mid-corner feels intuitive, though newcomers might find the rear brake overly sensitive—a common trait in trial bikes to facilitate rear-wheel steering.

The 1,305 mm (51.4") wheelbase strikes a perfect balance between stability and agility. During our test, switching between tight figure-eights and steep descents required no adjustments—just lean and commit.

Competition: How the Evo 300 2T Stacks Up

The 2012-2016 trial bike arena was dominated by four key players:

1. GasGas TXT Pro 300: Lighter steering but a harsher clutch pull. GasGas favored a racier powerband, which newer riders often found intimidating.
2. Sherco 300 SE: More premium components (Brembo brakes, Marzocchi forks) but 3 kg heavier. Sherco’s engine had a stronger mid-range but required stricter maintenance.
3. Montesa Cota 4RT 260: Honda’s four-stroke oddity. Smoother power delivery and fuel injection, but heavier (74 kg dry) and less "flickable" on off-camber sections.

The Beta carved its niche as the Goldilocks option—approachable for amateurs yet capable enough for experts. Its carbureted engine, while less refined than Montesa’s FI, offered tunability that pros appreciated. Against the GasGas, the Evo’s clutch and ergonomics gave it an edge in endurance events.

Maintenance: Keeping the Evo 300 2T in Prime Condition

As MOTOPARTS.store’s in-house trial specialist, here’s my no-nonsense maintenance guide:

• Engine:
• Fuel Mix: Stick to the 1.5% oil ratio (60:1) with JASO-FD-certified oils. A leaner mix risks piston seizures.
• Top-End Rebuilds: Every 80-100 hours for casual riders. Competition use? Halve that interval.

• Carb Tuning: The Keihin PWK 28mm is reliable but sensitive to altitude changes. Keep a jet kit handy.

• Suspension:

• Fork Service: Replace oil every 50 hours. Use 5W fluid for colder climates.

• Shock Linkage: Grease bearings every 20 hours—mud loves to invade here.

• Aftermarket Upgrades:

• Clutch Plates: Swap to sintered plates for heavier abuse.
• Air Filters: Twin-air foam filters improve airflow and are easier to clean.
• Brake Pads: Organic pads offer better modulation than sintered for trial use.

All recommended parts are available at MOTOPARTS.store, with tutorials to guide DIY servicing.
