Introduction to the Honda Grom

Launched in 2013 as the MSX125 in the Asian and European markets, the Grom quickly gained popularity for its distinctive design and ease of use. Honda introduced the Grom to the American market in 2014, where it continued to charm riders with its compact size and quirky character.

The name “Grom” is derived from the surf culture term “grommet,” referring to a young and enthusiastic surfer. The moniker aptly captures the spirit of the bike – youthful, energetic, and eager to make a splash.

At the heart of the Honda Grom lies a 125cc air-cooled single-cylinder engine, delivering just enough power to provide a thrilling riding experience without being overwhelming for new riders.

Over the years, the Honda Grom has undergone several updates, with each iteration refining its design and performance. Notable upgrades include the introduction of a new LED headlight, a revised exhaust system, and improved suspension components.

Despite these enhancements, the Grom has remained true to its core philosophy – delivering a fun and accessible riding experience that’s perfect for zipping around town or carving through twisty back roads.

What is Honda Grom Top Speed?

The Honda Grom is capable of reaching a top speed between 55-73mph right out of the box, although this could differ depending on elements such as weight load, wind resistance, and tire type.

Factors Affecting the Honda Grom Top Speed

  • Rider Weight

The Honda Grom is equipped with a 125cc engine, allowing for easy navigation around town. However, the power-to-weight ratio becomes relevant when considering top speed.

Lighter riders will usually maximum to greater velocities in comparison to heavier ones who may find themselves unable to accelerate as quickly and reach lower peak speeds due to the extra weight their motor needs to move.

  • Wind Resistance

Aerodynamics plays a crucial role in determining the Grom’s top speed. The Grom has a small profile and minimal wind protection, making the rider more susceptible to wind resistance. Riding in a tucked position can help reduce drag and increase top speed, but it might not be sustainable or comfortable for extended periods.

  • Tire Choice

The tires that come stock on the Honda Grom are budget-oriented and may not be optimized for high-speed stability. Upgrading to higher-quality tires designed for better grip and stability can not only improve handling but also contribute to a higher top speed.

Modifications to Increase Honda Grom Top Speed

  • Exhaust System

Looking to maximize the performance of your Honda Grom? An aftermarket exhaust system can do just that! Not only will it reduce weight and increase exhaust flow, allowing for more efficient expulsion of exhaust gases – resulting in a slight boost in top speed – but also provide an aggressive sound that amplifies the riding experience.

  • ECU Tuning

Tuning the ECU of a Honda Grom can unlock hidden potential and unleash higher performance. This is achieved by utilizing piggyback systems or stand-alone units that permit users to adjust parameters, such as fueling, ignition timing, and rev limits for enhanced power output and faster top speeds.

Be aware though; tinkering with your engine management system may void warranty coverage – so proceed with caution when it comes to emissions regulations!

  • Sprocket Changes

Changing the sprocket size on the Honda Grom can directly affect top speed and acceleration. The stock Grom comes with a 15-tooth front sprocket and a 34-tooth rear sprocket. By increasing the number of teeth on the front sprocket or reducing the number of teeth on the rear sprocket, you can effectively increase the Grom’s top speed.

Keep in mind that this modification typically comes at the cost of reduced acceleration, as the bike will have a higher overall gear ratio.

  • Other Modifications

Achieving a higher top speed necessitates some modifications, such as replacing the intake system, adding big bore kits to increase horsepower, or installing performance camshafts.

These are more expensive upgrades that usually have other supporting changes needed for maximal results – so researching them and talking with professionals is advised before making these decisions.
