2020 Yamaha PW50:

Features like adjustable throttle and fully automatic transmission ensure your child’s first riding experience will be all smiles.

One of the industry’s best-selling mini-bikes, the affordable PW50 is a fantastic entry-level youth bike that’s helped young riders learn the ropes of motorcycling for decades.

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.

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

A class-lowest 485 mm (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.
