The "Yamaha Zuma 125" is a scooter introduced by Yamaha Motor Company in September 2008. It is a 124cc 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 it's overall form and dual headlight configuration. It's size is slightly larger, as well as the inclusion of a metal bracket around the headlights. The Taiwanese, Japanese and South American models have stacked front lights with a single headlight. The type of bulbs used are HS1 styled halogen lights.
It is intended to perform the role 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

The engine's specifications are listed as "fuel-injected 124cc single cylinder 4-stroke engine, which uses an SOHC 4-valve head with 10:1 compression ratio, and ceramic-composite cylinder plating" [http://www.yamaha-motor.com/sport/products/modelfeatures/608/0/features.aspx] . 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. There is currently an established aftermarket with numerous parts that allow the engine to be enlarged up to 300cc. This same engine (minus the fuel injection) is also used in Yamaha's Cygnus x scooter.

Depending on driving style and riding conditions, the Zuma 125's fuel economy is around 89 mpg.
