What Factors Affects Honda Grom Top Speed?

While searching for Honda Grom’s top speed, you must have seen different values claimed by riders. The top speed value differs because many external factors are associated with it.

Let’s find out what factors affect the Honda Grom’s top speed-

1. Weight

The rider’s weight and other accessories dramatically affect the top speed of the Honda Grom or any other motorcycle.

It’s because some power is consumed to carry that extra weight. Hence, if the rider is skinny, he will win the race with a heavyweight guy.

So, try to lose some pounds and reduce extra weight from your motorcycle to win the race. Even 2 pounds weight makes the difference in top speed.

2. Wind

Honda Grom is designed aerodynamically, but wind drag still tries to stop the vehicle. If the wind direction is against you, it’s tough to reach 59 mph. However, if the wind direction is along with you, the Honda Grom can go much faster.

So, bend down on the gas tank and keep your legs closed while riding your groom to minimize air resistance.

3. Road Conditions

The road conditions also affect the top speed. If you’re riding uphill, Honda Grom will not reach 50 mph. But, if you’re riding downhill, you’ll get the highest speed out of your Grom, which can reach up to 73 mph.

4. Tire Pressure

Have you tried moving a flattened tire motorcycle? You must have found it difficult. But it’s very easy to move a bike with good tire pressure. Many riders don’t pay attention to this area, but it affects the motorcycle’s top speed.

So, if you want maximum speed from your Honda Grom or any other motorcycle, maintain the tire pressure at recommended levels.

  • Front Tire Pressure: 32- 35 Psi
  • Rear Tire Pressure: 40- 42 Psi

5. Mods

Manufacturers are bound to emission norms and regulations, but mods can significantly improve a motorcycle’s top speed. A good-quality fuel injector, a better spark plug, good air intake, and exhaust can increase the Honda Grom’s power and top speed.

I have written a detailed guide on various methods to make a motorcycle faster. You can read that guide and follow those tips to increase your Grom’s top speed.
