The fun loving BWs 125 underwent a significant update in 2016. Not only did we revise the styling, but we also increased the under seat storage capacity, added a digital meter assembly and a rear disc brake. Not stopping there, no pun intended, the front disc brake diameter was increased and we made the cockpit more roomy too. Powered by a fuel injected 125 cc engine, the sporty BWs 125 makes a great urban or suburban commuter.

Engine: Peppy, 125cc, air-cooled (with fan assist), SOHC, 4-valve, 4-stroke engine produces solid, predictable power and excellent fuel economy.

Storage: Ultra-convenient, large 29 litre, locking under seat storage compartment can hold selected full-face helmets or other items such as a laptop computer, rain suit, etc.

Fuel Economy: Fuel consumption of approximately 37kpl/105mpg. Your actual consumption may vary.

  • Fully automatic CVT transmission
  • 245 mm front disc with twin piston caliper
  • 220 mm rear disc brake
  • Digital instrument with tachometer
  • Large 29 litre under seat storage compartment
  • Preload adjustable rear shocks

Engine Features
  • 125cc, air-cooled (with fan assist), SOHC, 4-valve, fuel injected, 4-stroke engine produces peppy, easy to use power with excellent fuel economy.
  • Fuel consumption rating of approximately 37 kilometers per litre or 105 miles per gallon (imp.). Your actual consumption may vary.
  • BWs 125 uses regular 87 octane gasoline.
  • Fast, dependable electric starting.
  • Maintenance-free transistor controlled ignition (TCI): produces a strong spark for fast starts; provides precise ignition timing / mapping for optimum engine performance at all rpms
  • Fan-assisted, air-cooling: maintains consistent engine temperatures even in stop & go traffic
  • 4- valve cylinder head: utilizes two intake & two exhaust valves; excellent breathing efficiency & excellent fuel economy
  • Roller rocker arm valve actuation: specially designed roller rocker arms reduce friction for increased power; reduce mechanical engine noise for a quiet, enjoyable ride
  • Intake & exhaust valves feature a special "carbon cutter" valve stem design: automatically removes carbon build up from the valve stems; maintains maximum engine efficiency & power, even during extended slow speed use; (carbon build up on valve stems can lead to sticky valves & poor performance)
  • Lightweight, aluminum cylinder features ceramic composite plating on the cylinder bore: insures uniform heat dissipation; coating enhances the thin film of oil between the cylinder & piston, reducing friction & increasing power
  • Wet sump-type oil delivery system with centrifugal oil filtering system: automatically removes any particles found in the oil
  • Automatic cam chain tensioner: reduces mechanical engine noise & maintenance time
  • Lightweight crankshaft & lightweight "gravity cast" aluminum piston: optimizes engine performance & provides fast throttle response; reduces mechanical vibration; crankshaft utilizes a carburized connecting rod for excellent durability
  • 24 mm, "closed loop" throttle body fuel injection system: excellent fuel economy & good throttle response; 6 hole injector optimizes fuel atomization for strong, peppy power; "closed loop system" uses an oxygen sensor to "sniff" spent exhaust & automatically adjusts the fuel / air ratio for reduced emissions; fuel injection benefits include choke-free starting, steady idling during warm up, excellent fuel economy & reduced emissions
  • Easy access, dual stage, foam and paper-type air filter is used. Air box design reduces intake noise.
  • Fully automatic CVT transmission (CVT = constantly variable transmission): "twist-the-throttle-and-go" operation; no clutch lever or gear shifting involved... the transmission is fully automatic.
  • Environmentally responsible exhaust system produces a very quiet exhaust note: muffler contains a honeycomb-style catalytic converter to reduce emissions
  • Air induction System (AIS) further reduces exhaust emissions: AIS system injects fresh air into the exhaust to ensure complete fuel combustion; also helps to maximize the function of the catalytic converters
Chassis/Suspension Features
  • Rugged "underbone-style" steel frame: makes getting on & off the BW's easy
  • Wheelbase, centre of gravity, weight distribution & tire design, have all been engineered to provide light, agile handling & great manoeuvrability.
  • 33 mm trailing axle front fork: 78mm (3.1") of wheel travel; rubber fork gaiters / boots extend service life of fork seals & protect inner tubes from chips
  • Adjustable, dual shock rear suspension: 80 mm (3.2") of wheel travel; good ride quality; 3 steps of spring preload adjustability allows rider to adjust for load or road conditions
  • Rugged, 5-spoke aluminum "mag" wheels with wide, tubeless tires: wide, aggressive, tubeless 120/90-10 tires front & rear; tires well suited for rough, "pot holed" urban roadways; tires provide lots of grip & help create BW's unmistakably fun look
  • 245 mm front disc brake with wave style disc & twin piston caliper: "wave style" rotor adds style & increases cooling (more surface area than a round disc); excellent stopping power
  • 200 mm rear disc brake with single piston caliper: excellent stopping power
  • Both front & rear brakes are hand-operated like on a bicycle... making riding simple and fun.
  • Spacious, 29 litre, lockable under seat storage: can hold selected full-face helmets; or everyday commuter items like rain suit, laptop, briefcase, etc.
  • Roomy, textured, one piece rider & passenger seat: provides excellent comfort & plenty of room; passenger grab rails for peace of mind
  • 6.5 litre fuel tank with locking gas cap: excellent fuel economy means an extended riding range & fewer fill ups; easy access, front fairing mounted, locking gas cap; in tank electric fuel pump
  • Multifunction, 3 in 1 main key switch: operates ignition, fork lock & under seat storage lock; special anti-theft "shutter" blocks ignition key hole access to prevent tampering
  • Comprehensive, compact, sporty meter assembly: all digital readouts; readouts include; speedo, odometer, tach, trip meter, clock & fuel gauge
  • Dual style, 55 watt H1 main headlight with projector style high beam light: excellent illumination & rider visibility; design enhances BW's tough yet sporty styling
  • Full-size floorboards & wide front apron: excellent wind & weather protection
