2012 Yamaha PW Review


For parents with kids who want to ride, finding a good entry-level bike can be a bit of a challenge. This is where the 2012 Yamaha PW50 steps in. With a seat height of only 19.1 inches, the Yamaha PW50 is a great bike to learn on, particularly when additional safety and control features are taken into consideration.

The air-cooled, 49cc, two-stroke engine of the 2012 Yamaha PW50 is one of the quietest engines in its mini-bike class. Coupled with the automatic transmission, the engine provides single-speed power that is easy to use. All the rider needs to do is start the engine and go. While this simplistic layout won’t appeal to adults and older riders, it is an excellent choice for young children, especially those that are new to riding.

Removing the complexities of shifting gears with a manual transmission makes learning to ride more enjoyable. It also allows youngsters to improve at the skills needed to control and balance the bike before adding in shifting gears. Once the bike is moving, all the rider needs do is concentrate on the ride ahead. Braking is also relatively simple, as brake handles resemble those found on bicycles ensuring that riders will be recognize the handles and know how to use them.

The ignition for the 2012 Yamaha PW50 is a key-type ignition, which allows the adult in charge to control when riding occurs. Additional safety features provide adults with a measure of control over how quickly the rider is going. The throttle has an adjustable screw stop that provides adults with a way to limit the speed of the bike. By manipulating the screw stop, the speed can be increased gradually over time as the skill of the rider increases. A choke lever is located directly in front of the main switch to allow ease of access when necessary.

The low seat height of the 2012 Yamaha PW50 means that most kids will be able to place both feet firmly on the ground, and the mini-bike has a low center of gravity. As well as enhancing the rider’s handling ability, being able to balance the bike will also develop confidence. The telescopic front fork absorbs most bumps allowing for smoother handling while riding. Although the 2012 Yamaha PW50 sports a lightweight chassis, it is made from polypropylene to provide additional strength to the mini-bike.

The 2012 Yamaha PW50 sports a relatively simplistic design, which means that maintenance is kept to a minimum. The mag-style wheels mean that adults will not have to deal with replacing broken spokes. The shaft drive system is exclusive to the mini-bikes class. It is fully enclosed to improve durability, and since there is no chain to repair, it is almost maintenance-free. The engine is equipped with an autolube oil injection system, so that pre-mixing of fuel and oil is no longer required.
