SYM Wolf SB 250 Ni (2012-2015) Review: The Underdog That Packs a Surprising Bite

Introduction

The SYM Wolf SB 250 Ni is one of those motorcycles that quietly defies expectations. Produced between 2012 and 2015, this Taiwanese naked bike combines approachable dimensions with a spirited 250cc engine, making it a compelling option for both urban commuters and weekend explorers. While it never achieved the cult status of Japanese rivals, its balanced performance and robust build quality deserve a closer look. After spending a week with a well-maintained 2014 model, here's why this Wolf might just be the dark horse of the lightweight naked bike segment.

Design & Ergonomics

At first glance, the Wolf SB 250 Ni adopts a minimalist neo-retro aesthetic that straddles modern and classic influences. The teardrop fuel tank (14L capacity/3.7 US gal) flows into a stepped seat that looks sportier than it feels. SYM offered six color options during its production run, ranging from vibrant red to understated matte grey, with my test bike sporting the latter in a surprisingly premium finish.

The 790mm (31.1") seat height is where this bike truly shines. Even for riders under 170cm (5'7"), flat-footing at stops feels natural, inspiring confidence in stop-and-go traffic. However, the thinly padded seat becomes noticeable after an hour of riding – a common tradeoff in this segment that could be remedied with an aftermarket cushion from our [MOTOPARTS.store seat upgrades collection].

Controls fall neatly to hand thanks to a narrow 790mm (31.1") width. The digital-analog combo gauge is refreshingly legible, featuring a gear position indicator that new riders will appreciate. While the switchgear lacks the tactile feedback of premium brands, everything functions with satisfying precision.

Engine & Performance

Beating at the heart of this Wolf is a 249.4cc liquid-cooled single-cylinder engine that punches above its weight class. The 4-valve SOHC design with electronic fuel injection delivers 24.7 HP (18.4 kW) at 7,500 RPM and 23.1 Nm (17 ft-lbs) of torque at 6,000 RPM. These numbers translate to real-world usability rather than outright speed, but don't mistake that for being tame.

From idle, the engine exhibits a muted thrum thanks to its counterbalancer shaft – a rarity in single-cylinder bikes. Roll on the throttle below 3,000 RPM in higher gears, and progress is civilized if unremarkable. But keep the tach needle between 5,000-8,500 RPM, and the Wolf comes alive with a linear surge that feels more 300cc than 250cc. The 6-speed gearbox is a highlight, offering crisp shifts that make chasing the powerband genuinely engaging.

Top speed sits at an indicated 140 km/h (87 mph), though maintaining 120 km/h (75 mph) on highways requires some commitment. Where this engine truly excels is in urban environments. The EFI system delivers flawless cold starts and smooth low-speed modulation, while the 2.3L/100km (96 US mpg) fuel economy means you'll be visiting gas stations less often than your local coffee shop.

On the Road

City Riding:
With a tight 1320mm (52") wheelbase and 173kg (381 lbs) wet weight, the Wolf dances through traffic like a bicycle. The upright riding position provides excellent visibility, while the light clutch pull (despite being cable-operated) saves your hand during rush hour. The 288mm front disc with radial caliper offers strong initial bite, though adding a steel-braided line (available in our [brake upgrades section]) would enhance feel during aggressive stops.

Backroad Handling:
Push the Wolf into corners and it responds with neutral manners. The 110/70-17 front and 140/70-17 Maxxis tires provide decent grip, though experienced riders might opt for stickier rubber from our [performance tire selection]. Suspension leans toward the plush side – great for absorbing potholes but requiring deliberate weight transfer when pressing hard. That said, the steel diamond frame feels reassuringly rigid when cranked over.

Highway Manners:
At sustained speeds above 100 km/h (62 mph), the lack of wind protection becomes apparent. Vibration remains well-controlled thanks to the counterbalancer, but the seat's firmness starts nagging after 45 minutes. This is where the 6th gear proves its worth, dropping RPMs to a relaxed 6,500 at 100 km/h.

Competition

When stacked against contemporaries like the Honda CB300R and Yamaha MT-03, the Wolf SB 250 Ni holds its ground through clever engineering choices:

1. Vibration Control: The balancer shaft gives SYM an edge in refinement over single-cylinder rivals like the Suzuki GW250.
2. Maintenance Simplicity: Air-cooled competitors require more frequent oil changes, while SYM's liquid-cooled system maintains optimal temperatures.
3. Feature Set: The gear position indicator and LED lighting (on later models) were premium touches in this class.

Where it concedes ground is in brand recognition and aftermarket support – a gap that MOTOPARTS.store specifically addresses with our comprehensive [SYM Wolf parts catalog].

Maintenance & Ownership

SYM's reputation for reliability shines through in the Wolf's straightforward maintenance schedule:

1. Oil Changes: Every 5,000 km (3,100 miles) using 1.8L of 10W-40 JASO MA2 oil. Consider synthetic blends from our [lubricants department] for extended drain intervals.
2. Valve Adjustments: Every 10,000 km (6,200 miles) – simpler than shim-under-bucket systems found in Japanese rivals.
3. Cooling System: Use ethylene glycol-based coolant and inspect hoses annually. Our [cooling system kits] include OEM-spec replacements.
4. Chain Care: The O-ring chain requires regular cleaning and lubrication. Our [chain maintenance bundle] simplifies this crucial task.

Common upgrade opportunities include:
- Upgrading to NGK Iridium spark plugs (CR8EIX) for smoother cold starts
- Installing adjustable levers for better ergonomics
- Swapping to premium brake pads for enhanced stopping power

The SYM Wolf SB 250 Ni won't set your pulse racing with headline-grabbing specs, but it delivers where it counts – as a dependable, engaging companion for daily rides. The combination of accessible ergonomics, surprising refinement, and low running costs makes it particularly appealing to new riders or those downsizing from larger machines.

While original parts support has waned over the years, MOTOPARTS.store ensures this Wolf can stay howling on the roads for years to come.
