Yamaha YZ85 Specs and Features:

This section specifies what makes the Yamaha YZ85 such a great bike. Let us have a glance at most of the premium specs and features of the YZ85:

1. Presence of Reed-Valve Induction

The reed valve is a major component in the working of a motorbike. This mechanism in the YZ85 makes sure the fresh fuel intake only moves in a single direction, from the carburetor to the crankcase. It also improves the efficiency and power output of the entire system.

2. 6 Speed Gearbox

Having a motorbike strongly means that the user might be inclined to drive it at high speeds on various highways. A lower RPM can always mean a blessing in terms of motor vehicle specs. A 6-Speed Gearbox, in comparison to the more common 5-Speed, helps save more fuel at a lower RPM! It is a moderately efficient aspect of the YZ85, making it another selling point of the vehicle.

3. A Cool Affair

One of the most spectacular things about the Yamaha YZ85 is the presence of a Liquid Cooling System. This is much more efficient than an air-cooling system because it offers a higher thermal conductivity. In addition, water is widely available with a non-toxic resource, which makes it very cost-effective as well.

Another major advantage of the liquid cooling system is that the engine fails to overheat even at high RPMs. As the YZ85 has a two-stroke engine, it produces more friction and torque, increasing amounts of heat! Thus, the availability of the liquid cooling system prevents any kind of damage to the engine through overheating.

4. The Charm of Inverted Fork Suspension

The inverted fork is much lighter than a regular fork. This decreases the overall weight, giving the user a much smoother feel on the front end. The inverted fork also makes up for a much more comfortable ride with better handling and control of the vehicle. Overall, this type of suspension can help elevate the experience of the bike as a whole.

5. Hydraulic Brakes Work Their Magic

Ever since hydraulic brake systems came into light, the use of conventional brakes has reduced drastically. Both the front and rear brakes of the Yamaha YZ85 comprise hydraulic disc brakes. Hydraulics is a better option than conventional ones since they act much faster. when coming to a sudden stop

Additionally, hydraulic brakes last longer since the engine’s heat or friction is spread much more evenly throughout the whole system. It is also very simple to repair broken brakes since hydraulic disc systems are available almost everywhere for quick retrieval.

6. Semi Double-Plated Frame

Last but not least, the YZ85 accommodates a double-plated frame at one end and a single-plated frame on the other end. This gives the motorbike a much more rigid shape with extra strength. At much leaner angles and heavy or sudden braking, the semi-double-plated frame can be a great choice in comparison to single-plated ones. This combination also makes for a great aesthetic with a slimming look!

Yamaha YZ85 Top Speed

The top speed with a Yamaha YZ85 is a staggering 65 miles per hour. This can easily be converted to 105 kilometers per hour for a better and bigger picture. For an 85-cc motorbike, it is quite impressive, but it does have room to improve.

One important reason as to why this vehicle has such an exciting speed range is due to the presence of the reed valve induction system. This makes the single-cylinder, two-stroke engine much more powerful, hence propelling the bike to further limits and higher speeds!

With a price tag that is Yamaha YZ85’s, it can easily be said that the motor vehicle can easily steam ahead of its competitors within the same price range. Nevertheless, there are some ways to increase the top speed of the YZ85. In the next sections, we will look at some of the most used and straightforward ways of achieving so.

How To Increase The Yamaha YZ85’s Top Speed?

Although the Yamaha YZ85 is great as it is, there are some aspects of the vehicle that you could try changing up for a much better result overall. Granted, these may cost a few hundred bucks, but who wouldn’t love a Zip in performance of their favorite racing bike?

Hence, keep a sharp eye out, as this information is too precious to lose out on. Maybe you are in for some significant improvements for your joyride:

1. Performance Air Filters

If your engine has optimum airflow, it can give you some magical moments with your Yamaha YZ85. One major way to improve the airflow to and from the engine is to install performance air filters. As the job of this filter is to stop any kind of dirt or dust from entering the valves, it can surely go a long way to support great airflow and ultimately increase the top speed of the Yamaha YZ85.

2. Gear Ratio Switch

Gear ratio can play a vital role in how your vehicle might power through various scenarios. You can choose and optimize your gear ratios based on how you want the performance, that is if you want low-end power or you would love to maximize the top speed. With the aid of a higher-teeth front sprocket, the bike will push through more distance for each engine’s revolution. This significantly helps in increasing the ultimate top speed but does so at the cost of slower accelerations.

3. Better Exhaust Systems

A better horsepower can play an intriguing role in increasing the top speed of any motor vehicle. The same can be done with the Yamaha YZ85 by installing better exhaust systems. These systems prevent the build-up of hot waste gasses from combustion in the engine, providing room for more air to flow in and out. The horsepower enhancement can be as big as ten percent in most common performance exhaust systems! Although it might cost a hefty amount to replace the existing system on your bike, if the top speed is your main priority, it might as well be worth it to do so!
