Age (11-14)

2020 Yamaha YZ 85 is the new legend in the young motocross scene. The dirt bike can surely turn a rider’s dream into a reality.  The new Yamaha YZ is out to dominate the 85cc category. This dirt bike comes with a new YPVS engine equipped with exhaust, transmission, and a full valve with revised intake. Yamaha YZ85’s new adjustable environment features new swingarms, new brake rotors, and other features. It will surely put your kid in a position to win multiple races.

Due to its 85cc chilled liquid and its valve power, the dirt bike does not lose peak power at micro circle levels. 2020 Yamaha YZ85’s lightweight both from the front and rear rims are durable. In addition, the rims work best to produce optimum suspension performance by reducing the non-emerging weights. Thanks to the new joystick mount, one can adjust the handlebar to suit their desires. 

Chassis 

Compared to the 2018 test mule, the updated chassis and suspension outperforms the latter. Both were the things the “young horses”, the 85cc riders have been waiting for, for the longest time. Riders have more control over the new fork holds as it can be adjusted to a wide range of riders. Besides, the shock is a balance to keep the electric dirt bike in position even while riding downhill.

The new expansion chamber of the YPVS enhances power delivery in both low and medium-range by enhancing exhaust gas flow. The dirt bike has updated smooth transitions and better gear engagement compared to the 2019 YZ85. It has a large radiator, loops, aluminium water pumps, and large cores are good for cooling. Finally, the air filter is designed to enhance air cleaning and very easy maintenance.

2019 Yamaha YZ85 Review

2019 yamaha YZ85, yz85 review

Age group 9-14

There are only a few dirt bikes around the 85cc engine range. A shakeup has occurred over the past ten years in the 85cc two-stroke class with only some bike manufacturers keeping a bike in this range. Some, like Honda, decided to withdraw totally and concentrate its effort on the production of 150cc four-stroke model. Yamaha has a great offering with their 2019 Yamaha YZ85 dirt bike.

Designs for the 2019 Yamaha YZ85 dirt bike are focused on improving the power of the dirt-bike and even at a high revolution per minute (RPM), its optimum power output remains constant. The power output is predictable making it reliable during acceleration. Improvements were made on its chassis, making it more attractive and its steel reinforcement makes it even more rugged. The new Kayava fork setup makes for great compression and bump absorption. Older versions of this dirt bike had an inconvenient handle-bar, but with the introduction of adjustable handle-bar, this problem has been fixed, it now has four positional adjustments, allowing it to be altered according to the rider’s preference and size. Its braking system also was improved with new brake-line in front for comfort when braking. Its sub-frames are now detachable.

Feedback on the 2019 Yamaha YZ85 has been good so far. Overall, the 2019 Yamaha YZ85 is a great dirt bike to purchase as your child progresses in their riding skills, and as it is now more adjustable this allows for more use at a time when your child will be growing quickly. The other advantage is that many of the Yamaha YZ65’s parts are interchangeable with the Yamaha YZ85 parts.
