The Yamaha Zuma 125 is a scooter introduced by Yamaha Motor Company in September 2008. It is a 125cc version of its smaller 49cc cousin, the Zuma. Outside the United States it is known as the Yamaha BWS 125.

Model information

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.


The engine's specifications are listed as "fuel-injected 125cc single cylinder 4-stroke engine, which uses an SOHC 4-valve head with 10:1 compression ratio, and ceramic-composite cylinder plating"[1]. 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 11 horsepower. After the break in period, the Zuma 125 can achieve a maximum speed of around 55 mph (88 km/h).
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 300cc.

Depending on driving style and riding conditions, the Zuma 125's fuel economy is around 90 mpgUS (2.6 L/100 km)(109 mpgImp).
