2018 Yamaha PW50 Review on Total Motorcycle:

Featuring nothing but smiles on your child’s face with its no-shift fully automatic transmission, low seat height and adjustable throttle control.

This is where champions get their start.

One of the industry’s best-selling mini-bikes, the PW50 is a fantastic entry-level bike designed to help young riders learn the ropes at an affordable price.

Off-road adventures begin here.

When it comes to kids’ mini-bikes, Yamaha is the clear leader. With the PW50’s rider-friendly design it’s easy to see why this 50cc 2-stroke is a firm favourite with kids and parents. Safety features include an adjustable throttle which allows parents to limit top speed to suit the rider’s skill level – and the enclosed shaft drive reduces maintenance chores. And there’s no gear shifting to worry about, its zippy 50cc 2-stroke engine drives through a fully-automatic gearbox for simple ‘twist-and-go’ performance.

At just 39 kg, this lightweight and compact mini-bike is the ideal way for your child to have hours of fun while developing their riding skills.


Air-cooled, 49cc, reed-valve, 2-stroke single is mildly tuned to deliver predictable power that gently eases the new rider up the off-road learning curve.

///Rider Confidence

Class-lowest 485mm (19.1″) seat height creates a handling-enhancing low centre of gravity and allows most riders to put both feet on the ground for added confidence.





2018 Yamaha PW50 Totalmotorcycle.com Key Features

Fully Automatic Transmission
Fully automatic transmission means no shifting required; the PW50 is a twist-and-go package.

Entry-Level Two-Stroke Motor
Gutsy 49cc two-stroke is built to thrill without intimidating beginners.

Ultra-Low Seat Height
A seat only 18.7 inches high makes the PW50 the ideal choice for the littlest rider in the group.

An adjustable throttle stop screw lets the adult in charge gradually increase speed as skills improve.

Low Maintenance Requirements
Shaft final drive means no chain maintenance, while Yamaha’s exclusive autolube oil injection system eliminates the need for fuel/oil premixing.
