125cc ATV Features

Maximum Speed

All quad bikes, or all-terrain vehicles, include a feature that controls the top speed. This safety component allows kids and inexperienced drivers to use the ATVs, which, if misused, can cause accidents.

The smallest engine size on ATVs is 110cc, which can be driven by three to seven-year-olds. Next in line is the 125cc ATV, which is recommended for eight to sixteen-year-olds but can be used by adults too.

The average maximum speed for a 125cc ATV is between thirty to thirty-five mph. However, this does not mean that ATVs cannot go faster. Owners can easily modify their ATVs to increase their average top speed.

Also, race-specific machines can reach maximum speeds comparable to dirt bikes. Terry Wilmeth clocked the fastest speed recorded on an ATV on his ALSR Rocket Raptor Version. He hit a max speed of 196.19 mph on his quad, a modified Yamaha 200 Raptor, on 15 June 2008.

Top Speed

What limits the speed of your ATV? Is there a way to make your ATV faster? The short answer is yes. Here are three ways how you can do it:

Remove the Speed Controller

The speed limiter can either be mechanical or electronic. So, you can remove an adjustable screw usually found on the handlebar or modify the airflow to the engine. Meanwhile, an electric speed controller automatically reduces the fuel flow to the engine to slow down the ATV.

Change the Gear Ratio

A higher gear ratio gives you two options: more acceleration or a faster ATV. So, you need to see what works best for you.

Up Your Air Filter

Replacing your ATV’s air filter with a lifetime replacement filter improves airflow to the engine, providing it with more power. Also, don’t forget to regularly check and clean your filters, as blocked filters affect the quad’s performance.

Difference Between Dirt Bikes and ATV

If you are looking for speed, it is easy to get confused between choosing a sports bike instead of an ATV. Here are five differences between the two vehicles.

Difference Between Dirt Bikes and ATV

  • Engine Type: A bike’s engine is more fuel-efficient than an ATV. ATVs are heavier rides and require more engine power to move. Some dirt bikes have a two-stroke engine, making them even lighter and using less fuel than a four-stroke.
  • Speed: A sports bike leaves an ATV biting its dust when it comes to top speeds. Also, a dirt bike is suited to a wider variety of terrains.
  • Life Span: ATVs have a longer life span than dirt bikes, which are more susceptible to wear and tear and damage.
  • Stability: As with most things, four wheels are better than two. The ATV is a more stable vehicle compared to the bike.
  • Learning Curve: It is easier for new drivers, especially kids, to use an ATV instead of a bike.

Conclusion

A 125cc quad bike is a fun way to start using ATVs. Even though the top speed can hit thirty mph, 125cc ATVs come with several safety features. These include speed controllers that set the ATV’s top speed for learning and inexperienced drivers. You can also up the speed limit on your ATV, but always keep in mind safety first and check your state’s legal requirements.
