Overview

The Yamaha PW 50 is a minibike in the PW family, produced from 2002 through 2027. The 2027 model has a 49.0 cm³ air-cooled, two-stroke single producing 5.4 hp (4 kW), with 0.4 Nm of torque at 4,500 rpm; wet weight is 40.8 kg.

Its 475 mm seat height and 40.8 kg wet weight make it easy for a small rider to get settled and maneuver at low speed. The automatic transmission and centrifugal clutch remove the need to operate a clutch, while shaft drive avoids chain cleaning and adjustment; the 1.90-liter tank feeds a carburetor, and a separate tank supplies the two-stroke oil.

Pros and cons

Advantages

Low seat and light weight
A 475 mm seat and 40.8 kg wet weight make the bike manageable for a small rider.
Automatic clutch
The centrifugal automatic clutch means the rider does not have to operate a clutch lever.
Shaft final drive
Shaft drive avoids the cleaning and adjustment required by a chain.

Things to consider

Drum brakes
Drum brakes at both ends offer less direct braking response than disc brakes.
Kick start only
Starting requires a kick, with no electric starter as an alternative.
Limited ground clearance
The 95 mm ground clearance leaves little room for clearing raised obstacles.

Estimated ground reach

Both feet likely flat

You should have a stable stance at a stop, although seat width and suspension setup still matter.
