Benelli BN 125 CBS (2021-2022): A Nimble Companion for Urban Adventures
Introduction
The Benelli BN 125 CBS represents a compelling entry into the lightweight naked bike segment, blending Italian-inspired design with practical commuter DNA. Introduced in 2021, this 125cc machine targets urban riders seeking agility, fuel efficiency, and approachable performance. Over two years of production, it carved a niche as a stylish alternative to utilitarian commuters, offering just enough flair to stand out in city traffic while maintaining the simplicity new riders crave. Let’s dissect what makes this Benelli tick – and whether it deserves a spot in your garage.
Design & Ergonomics: Euro Flair Meets Everyday Functionality
Benelli’s design team injected surprising character into this entry-level package. The BN 125’s trestle frame and sharp tank lines echo its larger displacement siblings, creating visual bulk that belies its 142 kg (313 lb) curb weight. The 770 mm (30.3") seat height accommodates shorter inseams without sacrificing ground clearance, though taller riders might find the ergonomics slightly cramped during extended rides.
Color options (Red, Black, White, Green) pop under sunlight thanks to decent paint quality, while the LED headlight cluster adds modern appeal. The digital dash, though basic, provides clear readouts for speed, fuel, and gear position. Build quality feels adequate for the segment, though some panel gaps remind you this isn’t premium Italian craftsmanship.
The riding position strikes a balance between commuter uprightness and slight forward lean – enough to feel engaged without straining wrists. Narrow handlebars enhance flickability, though broader-shouldered riders might appreciate aftermarket bars for better leverage.
Engine & Performance: Small Displacement, Big Personality
At its heart lies an air/oil-cooled 125cc SOHC single-cylinder, producing 11.1 HP @ 9,500 RPM and 10 Nm (7.4 lb-ft) @ 7,000 RPM. These numbers won’t set records, but the EFI-equipped mill delivers smooth, predictable power perfect for urban environments.
Key characteristics: - Throttle Response: The Delphi MT05 ignition system ensures crisp cold starts and linear power delivery - Fuel Efficiency: 1.7L/100km (138 MPG) makes it cheaper to run than most electric scooters - Gearbox: The 5-speed transmission shifts with positive clicks, though finding neutral can be finicky at stops - Vibration: Minimal buzz below 8,000 RPM; mirrors stay readable even at 70 km/h (43 mph)
The real magic happens between 6,000-9,000 RPM. Keep the engine singing in this range, and the Benelli maintains pace with city traffic effortlessly. Top speed hovers around 105 km/h (65 mph) tucked in, but sustained highway riding isn’t its forte.
Handling & Ride Quality: Dance Through Traffic
Benelli’s chassis engineers deserve applause here. The steel trestle frame and USD fork (35mm diameter) provide surprising composure over broken pavement. Front suspension travel of 111 mm (4.4") soaks up potholes better than segment norms, while the preload-adjustable rear monoshock handles everything from solo commuting to occasional pillion duty.
Key dynamics: - Turning Radius: Tight enough for U-turns in narrow alleys - Tire Feedback: 110/80-17 front and 130/70-17 CST tires offer decent grip for dry conditions - Braking: CBS-linked 240mm discs provide adequate stopping power, though aftermarket pads improve bite
At 1360 mm (53.5") wheelbase, the BN 125 changes direction with almost scooter-like ease. Push hard into corners, and the suspension maintains composure – a rarity in budget 125s. The 190 mm (7.5") ground clearance allows respectable lean angles before peg feelers touch down.
Competition: How It Stacks Up
Honda CB125F
- Pros: Legendary reliability, 150 MPG+ efficiency
- Cons: Dated design, drum rear brake
- Benelli Edge: Superior suspension, modern EFI system
Yamaha MT-125
- Pros: 15 HP liquid-cooled engine, premium components
- Cons: 25% price premium, higher seat height
- Benelli Edge: Lower running costs, easier maintenance
KTM 125 Duke
- Pros: Sporty character, full-color TFT display
- Cons: Harsh ride quality, premium fuel requirement
- Benelli Edge: Comfort-focused ergonomics, vibration control
The BN 125 CBS carves its niche by balancing style and substance. While not the most powerful or tech-laden, it offers the best compromise for riders valuing everyday usability over outright specs.
Maintenance: Keeping Your Benelli Happy
As MOTOPARTS.store’s resident gearhead, here’s my maintenance cheat sheet:
- Oil Changes:
- 1.2L of SAE 10W-40 (API SH) every 5,000 km
-
Upgrade to synthetic for smoother cold starts
-
Chain Care:
- 130-link chain needs adjustment every 1,000 km
-
Consider DID VX3 chains for extended lifespan
-
Brake Fluid:
- Flush DOT 4 fluid annually to maintain CBS efficiency
-
Steel-braided lines improve lever feel
-
Spark Plugs:
- NGK CR7HIX iridium plugs extend service intervals
-
Check gap every 10,000 km
-
Tire Upgrades:
- Swap to Michelin City Grip 2 for wet weather confidence
- Maintain 1.9 bar (28 psi) front / 2.1 bar (30 psi) rear
Pro Tip: Install an aftermarket oil cooler if frequently riding in stop-and-go traffic – keeps engine temps stable during summer months.
Conclusion: The Urbanite’s Italian Stallion
The Benelli BN 125 CBS won’t satisfy speed demons or cross-country tourers. But for what it is – an affordable, stylish commuter with surprising depth – this little Italian delivers. The combination of Euro 4 compliance, CBS safety, and 58.8 km/l efficiency makes it a rational choice, while the aggressive styling and throaty exhaust note satisfy emotional cravings most 125s ignore.
Is it perfect? No. The mirrors vibrate at highway speeds, the seat foam compresses on long rides, and the 13.5L tank could be larger. But these are nitpicks in a package that nails its core mission – making every grocery run feel like a mini-adventure.
For current owners, consider these MOTOPARTS.store upgrades to elevate your BN 125:
- CNC adjustable levers for better ergonomics
- DNA air filters for sharper throttle response
- Puig windscreen for reduced fatigue on breezy days
In the pantheon of 125cc motorcycles, the Benelli earns its place as the thinking rider’s choice – a machine that prioritizes riding joy over mere transportation. And isn’t that what motorcycling’s all about?
