Honda CB125R
What is the Honda CBR125R / CBR125
The Honda CBR125R (also often just “CBR125”) is a 125 cc single-cylinder sport bike produced by Honda, targeted at new riders, commuters, and those who want sporty looks & fairing in a small displacement package. It is positioned in entry-level sport class — not high performance, but good balance of styling, fuel economy, ease of use, and Honda reliability. It features sport bike styling (fairing, clip-on style handlebars or semi-sport bars, sporty bodywork), but with engine output tuned more for tractability than outright speed.
Engine & Transmission
-
Displacement: ~ 124.7 cc single-cylinder, 4-stroke, liquid-cooled.
-
Valve setup: SOHC, normally 2 valves (older models); fuel injection in recent ones (PGM-FI). Some older/earlier versions used carburetor.
-
Bore & stroke: ~ 58 mm × 47.2 mm in many models.
-
Compression ratio: ~ 11.0 : 1.
-
Power: ~ 13.6 hp (≈ 10 kW) at ~10,000 rpm.
-
Torque: about 10.6 Nm (or ~10-11 Nm) at about 8,000-8,250 rpm depending on model year.
-
Transmission: 6-speed manual gearbox. Clutch is wet multi-plate type.
Chassis, Suspension, Brakes, Tyres
-
Frame: Steel double cradle frame in many versions.
-
Front suspension: Typical models have a telescopic fork in front, ~31 mm diameter.
-
Rear suspension: Monoshock (rear damper) in many versions; adjustable preload often included.
-
Brakes: Disc brakes both front & rear. Front disc size ~276 mm with twin-piston caliper, rear disc ~220 mm with single-piston.
-
Tyres & wheels: Front tyre ~ 100/80-17, rear ~ 130/70-17 in many older/standard models. Seat height ~ 795 mm. Wet weight ~ ~127-137 kg depending on model and variant.
Dimensions & Other Technicals
-
Length / Width / Height: Around 1,920-1,946 mm length; width ~700-710 mm; height ~1,080-1,090 mm in many models.
-
Wheelbase: ~ 1,310 mm in several models.
-
Seat height: ~ 795 mm in many cases. Good for medium riders; can be tall for shorter ones.
-
Ground clearance: Typically ~ 185 mm in many versions.
-
Fuel tank capacity: ~ 10-13 litres in more recent / higher spec models. Earlier versions had ~10L; some later had ~13L.
-
Weight: Dry or wet weight around 115-137 kg depending on year and equipment.
Performance & Ride Feel
-
The bike is not extremely fast (not meant to be). With ~13-14 hp, it offers decent acceleration for its class, but overtaking at high speeds or cruising on highways is limited. It’s best suited for city riding, light highway stretches, and for riders new to motorcycling.
-
Top speed in many markets is around 110-120 km/h (although this depends on rider weight, road, wind etc.).
-
Fuel efficiency is strong (one of its key selling points). Older versions with carburetor or early fuel injection generally return good mileage; some sources mention ~52.5 km/L under gentle riding conditions.
Styling & Features
-
Sporty fairing and bodywork: The CBR125R has a full fairing (in many regions), giving sport bike looks. The design tends to be aerodynamic, with sharp lines, and styling cues from larger CBR models.
-
Instrument cluster: Usually analogue + digital mix; displays speed, RPM, maybe fuel gauge etc in many models. More modern / recent versions might have more advanced display, depending on market.
-
Lighting: Standard headlights, tail lamps etc. In many markets, the lights are halogen or traditional style; newer ones sometimes have LED indicators or updated lighting.
-
Other features: PGM-FI (fuel injection) in newer/upgraded models gives smoother throttle response, better cold start, better emissions. Electric start, standard mirrors, foot pegs etc. Some markets may also offer under-seat storage or very small cubby depending on design.
Pros & Cons
Here are strengths and weaknesses based on cumulative user reviews, spec sheets etc.
Pros:
-
Reliability & build quality: Honda’s reputation works here. Owners generally report robust engines, good durability, and long-term reliability.
-
Fuel economy: Very good fuel efficiency, particularly in city riding or moderate speeds. Makes it cheaper to run.
-
Sporty looks in small package: For buyers who want sporty/fairing style, the CBR125R offers that aesthetic without going to large displacement or cost. Good entry into sport bike styling.
-
Light weight & manageable handling: Because it’s small and light, it’s easy to manoeuvre in traffic, low speed, parking etc. Good for beginners.
-
Six-speed gearbox & decent equipment: Having 6 gears (rather than fewer) helps in making use of engine revs; fuel injection and disc brakes both front & rear add to usability, safety.
Cons:
-
Limited power: With ~13 hp, acceleration is modest; overtaking on highways, high speed cruising will be limited. For taller riders or heavier loads/pillion, performance may feel stretched.
-
Comfort: Being a sport-style bike with fairings and possibly more aggressive posture, long rides or frequent highway riding might fatigue the rider. Also seat size in some models is compact.
-
Low torque at low rpm: The engine delivers peak torque high up (~8,000 rpm), which means that for city riding, initial pull from stop can feel less strong; you need to rev.
-
Features are basic: Compared to newer bikes in market, the CBR125R may lack modern features like ride modes, advanced displays (TFT), traction control etc (depending on region/year).
-
Cost of ownership for imported or older models: Depending on where you buy, spare parts might be costlier; servicing older models may have challenges; resale values vary.
Variants / Market Differences & Updates
-
The CBR125R history shows changes over years: earlier models used carburetors; later ones moved to fuel injection (PGM-FI) for better emissions, better throttle response.
-
In some markets it’s discontinued or replaced by other Honda models or naked versions (e.g., CB125R) which share many components but have different styling.
-
Some recent updates in certain markets include improved emissions compliance, small styling tweaks, enhanced lighting etc. However, globally not every market has the latest version.
Who Is It Good For, & Where It Fits
-
Ideal for new riders who want sportbike looks without big costs or big displacement. Good learning platform.
-
Great for city commuting: frequent stops/starts, traffic, low speed manoeuvres, tight parking.
-
Also suits those who want to ride on weekends, short highway stretches, or country roads—not for long touring or high speed sustained cruising.
-
Good option where regulations/licensing restrict displacement / power (e.g. in many countries, 125 cc is entry class).
Real-World Numbers & Examples
-
Fuel economy: Many users report high mileage; in gentle riding, it can give ~45-55 km/L depending on region, riding style & conditions.
-
Top speed: In many versions, ~110-120 km/h is realistic under ideal conditions (light rider, good road). Past that speed, wind resistance & power limitations become significant.
-
0-to speeds (like 0-60 km/h) are reasonable; overtakes take more time / gear shifts because engine needs to rev high.
Price & Value
-
Price depends heavily on region, year, whether new vs used, import taxes etc. In some markets, it has been a bit expensive for what power it offers, but the brand value, reliability and styling tend to offset that for many buyers.
-
Given its lower running costs (fuel, maintenance), it's often considered good value for people who don’t need a high power bike but want a sport aesthetic.
Final Verdict
The Honda CBR125 / CBR125R is a mature, proven motorcycle in the 125 cc sport-bike class. It does not try to be a performance monster, but what it does, it does well: reliable engine, good fuel economy, sporty appearance, ease of riding, decent components. If you're a beginner rider, or want a stylish commuter, or want a second bike for fun around town, it’s a very good choice.
However, if you expect to ride long highway stretches often, carry a pillion frequently, or want strong performance or modern electronic aids, you might want to consider stepping up to something in the 150-200 cc class, or look for more feature-rich newer bikes.
