The Yamaha Zuma 125 is a scooter introduced by Yamaha Motor Company in September 2008 and updated in 2016. It is a 125 cc version of its smaller 49cc cousin, the Zuma. Outside the United States it is known as the Yamaha BW's 125.
Model information
[edit]
The body design of the Zuma 125 is similar to the Zuma in respect to its overall form and dual headlight configuration. Its size is slightly larger, and it includes a metal bracket around the headlights. The Taiwanese, Japanese and South American models have stacked front lights with a single headlight. The bulbs used are HS1 styled halogen lights.
It is intended as a street-bike, with the capacity for handling light off-road conditions such as unpaved roads. Many of the design components like the steel frame, wide tires, oiled-type air filters, robust shocks, and front/rear off-road-style brush deflectors were included to facilitate both riding conditions.
Engine
[edit]The engine is a 123 cc 4-stroke SOHC 4-valve with 10:1 compression. The fuel injection system is similar to the ones installed on most Yamaha bikes, and uses a 24mm injector. The exhaust manifold comes equipped with an O2 sensor. The rated power output is close to 8 bhp (6.0 kW).[citation needed] After the break in period, the Zuma 125 can achieve a maximum speed of around 61 mph (98 km/h).[citation needed]
This same engine (minus the fuel injection) is also used in Yamaha's Cygnus-X scooter. There is currently an established aftermarket with numerous parts that allow the engine to be enlarged up to 287 cc.[citation needed] Depending on driving style and riding conditions, the Zuma 125's fuel economy is around 89 mpg‑US (2.6 L/100 km).
2016 Update
[edit]The bike was updated technically and cosmetically in 2016.[2] The dual independent headlamps were replaced by a single unit with integrated dual lamps, one for low beam and one for high beam.
