How to Increase the Speed of Honda Grom?

There are three ways that you can use to increase its speed.

  • Reduce The Overall Weight
  • Maintenance and Replacement of The Fork Oil
  • Invest in better brakes

Reduce the Overall Weight

To increase its speed first thing you can do is reduce its weight. For Instance, the curb weight of a Honda Grom is 223 lbs, but it would be best to sacrifice some performance criteria to reduce the bike’s weight so that you can travel faster. You can replace the stock lead-acid batteries with lithium-ion batteries. This will improve the fuel economy rating, acceleration, braking, and handling.

Maintenance and Replacement of the Fork Oil

If you want to increase its speed, the second thing you can do is take care of your bike and replace the fork oil in every regular maintenance. The 125 cc engine modification on your Grom bike becomes more rigid and inflexible when you refuel it with denser oil. To improve the single shock response in the rear tires, you should replace the old fork with thinner fluids, which flow faster. 

Invest in better brakes

You can get decent performance from the standard Honda Grom components, but you won’t be able to reach your peak performance. I know you guys are wondering why we are discussing brakes in the speed performance section, so let me tell you, this Grom bike has rubber counterparts that expand at high temperatures which resists the speed; on the other hand, steel braided kits withstand high temperatures more efficiently and does not affect the speed. So it is recommended that these original braking systems be upgraded with higher-performance aftermarket products after tuning.

Grom Engine

Honda Grom has a SOHC 124 cc four-stroke engine with a single-cylinder. To prevent the engine from overheating, it has an air-cooled system. Its Bore and Stroke ratio is 50mm x 63.1mm. It is a small motorcycle with compact power due to its aggressive compression ratio of 10:1. 

It has PGM-FI automatic fuel injection w/ 24 mm bore and five-speed manual transmission. The bike also comes with an electrical starter.


Grom Suspension

It has 31 mm telescopic inverted front forks with 3.9 inches of wheel travel, a single shock with a steel box-section swing arm, and 4.1 inches of wheel travel. These suspensions are fine when riding at low or medium speeds, but when you move toward high speeds, they become uncomfortable and transfer high bumps.


Grom Brakes

It has a single 220 mm disc with a hydraulic dual-piston caliper for the front wheel and a single 190mm disc with a hydraulic single-piston caliper for the rear wheel. They are still the same brakes that came with the third generation of Grom. Both brakes provide good braking, but it can be improved by replacing the stock brakes with steel braided kits. This improvement will increase the braking system along with the bike’s performance. This bike is also available with ABS brakes, but you have to pay some extra money to get this feature.

Price of Honda Grom

The Honda Grom base variant price is $3,499, but if you want the ABS one, then you have to pay $3,799. According to the looks and fun ride, the price is reasonable and highly affordable. Almost anyone can purchase it and enjoy its ride. 

Is it worth buying Grom in 2023?

Definitely, it is worth buying the Honda Grom in 2023. It is more likely that people will throw a thumbs-up or wave when they see you riding this unique small motorcycle. You don’t have to be a pro diver; anyone can ride on it due to its small size. 

Coming on the performance section, it has adequate speed, and most importantly, it will give a good fuel average. In addition, it requires little maintenance, so its owner won’t have to spend much on it. In case you are considering purchasing this machine, you should do so.


Can you make Honda Grom faster?

Yes, we can make Honda Grom faster by reducing its weight, improving its braking system, and regularly maintaining and replacing the fork oil.

Can a Honda Grom go on the highway?

There are different laws in different states; for instance, in California, a motorcycle with a displacement of 150cc or more can be ridden on highways with a motorcycle license endorsement. So you must check your state’s law before taking your Grom to the highway.

Is the Honda Grom has a 6-speed transmission?

No, Honda Grom does not have a 6-speed transmission; instead, it has a 5-speed transmission.

How far can a Grom travel?

One liter of fuel is enough for the Grom to travel 50km (31 mi). Therefore, with all his tanks full, which equals 10.5 liters, it can travel well over 500 km (326 mi) without refueling.
