Race-Ready Enhancements: Performance Upgrades for the Honda Grom

Engine and Performance Enhancements

Unleash the true potential of your Honda Grom with a range of performance-boosting upgrades. An aftermarket exhaust system, such as a Yoshimura Alpha T slip-on, delivers a throatier exhaust note while reducing weight and optimizing airflow. For improved throttle response and fuel efficiency, consider installing a fuel injection controller or a high-flow air filter from K&N or UNI.

Engine Enhancements Table

Upgrade	Benefits
Exhaust System	Improved power and acceleration, reduced weight, throatier exhaust note
Fuel Injection Controller	Enhanced throttle response, optimized fuel efficiency
High-Flow Air Filter	Increased airflow, improved combustion, better power delivery

For a more aggressive stance and improved handling, a rearset kit from Driven Racing or Woodcraft-CFM repositions the footpegs and controls for a more aerodynamic and race-ready feel. Upgrading to a braided stainless-steel brake line from Goodridge or Galfer provides enhanced braking performance and a more precise pedal feel.

Aesthetic Transformations: Customizing Your Grom’s Appearance

The Honda Grom is a beloved motorcycle known for its compact size and playful character. Aftermarket parts offer a vast array of options to enhance its appearance, allowing you to personalize your Grom and make it truly unique.

Customization Options

When it comes to customizing your Grom’s appearance, the possibilities are endless. Here are a few popular options to consider:

Bodywork: Replace the stock body panels with aftermarket fairings, cowls, and fenders in a wide range of colors and designs.
Lighting: Upgrade your headlights, taillights, and turn signals with LED or HID bulbs to enhance visibility and give your Grom a modern look.
Exhaust: Install an aftermarket exhaust system to improve performance and give your Grom a distinctive sound. From slip-on mufflers to full exhaust systems, there are options to suit every budget and preference.

Wheels and Tires

Swapping out your Grom’s wheels and tires can dramatically alter its appearance and handling. Consider the following:

Wheels: Choose from a variety of aftermarket wheels in different sizes, materials, and colors to customize the look of your Grom.

Tires: Experiment with different tire sizes and tread patterns to optimize grip, handling, and comfort.

Suspension and Brakes

Upgrading your Grom’s suspension and brakes can enhance both performance and aesthetics. Here’s how:

Suspension: Installing adjustable aftermarket suspension components allows you to fine-tune the ride height and damping for optimal handling.

Brakes: Enhance your Grom’s stopping power with upgraded brake pads, rotors, and calipers.

Improved Ride Experience: Comfort and Convenience Modifications

Increased Comfort: Upgraded Seats and Suspension

Upgrade your Honda Grom’s seat for enhanced comfort on long rides. Options include ergonomic designs, gel inserts, and heated seats for cold weather. Additionally, consider upgrading the suspension with adjustable shocks or a rear monoshock to improve handling and reduce road vibrations.

Enhanced Convenience: Saddlebags and Top Cases

Increase your Grom’s storage capacity with saddlebags or a top case. Saddlebags provide additional space for essentials, while a top case offers a more secure and spacious storage option. These accessories make it easier to carry items on short or long journeys.

Improved Ergonomics: Handlebar Risers and Footpegs

Adjust the ergonomics of your Grom to suit your riding posture. Handlebar risers elevate the handlebars to reduce wrist strain, while adjustable footpegs allow you to find the most comfortable foot position. These modifications enhance rider comfort and reduce fatigue during extended rides.

Accessorizing for Comfort and Convenience

Consider the following accessories to further enhance comfort and convenience:

Engine Swaps

The Grom’s diminutive size and light weight make it an ideal candidate for engine swaps. One popular option is the Honda Super Cub 125 engine, which offers a significant power boost while maintaining the Grom’s nimble handling. Other popular swap candidates include the Honda Monkey 125, Kawasaki Z125 Pro, and Yamaha Zuma 125 engines.

Bolt-On Power Boosters

For those who want to keep the Grom’s original engine, there are a variety of bolt-on performance upgrades available. These include exhaust systems, intake systems, camshafts, and carburetors. Each of these modifications can provide a small to moderate power boost, and when combined can result in a noticeable improvement in performance.

Intake Modifications

Replacing the stock intake system with a high-flow air filter and intake manifold can improve airflow to the engine, resulting in a small power boost. For even greater gains, consider installing a cold air intake system, which draws in cooler, denser air from outside the engine compartment.

Exhaust Modifications

Swapping out the stock exhaust system with a less restrictive exhaust system can improve exhaust flow and reduce backpressure. This can result in a slight power increase, as well as a more aggressive sound.

Camshaft Upgrades

Installing aftermarket camshafts with a more aggressive profile can alter the timing of the valves, allowing for greater airflow and improved performance. Camshaft upgrades can be a more involved modification, but they can provide significant power gains when combined with other performance modifications.

Carburetor Upgrades

The Grom’s factory carburetor can be replaced with a larger or performance-oriented carburetor to increase fuel flow to the engine. This can result in a noticeable power boost, especially when combined with other intake and exhaust modifications.

Suspension Enhancements: Handling and Stability Upgrades

The Honda Grom’s stock suspension can be adequate for casual riding, but if you’re looking for a more aggressive or comfortable experience, aftermarket suspension components can transform the Grom’s handling and stability.

Front Fork Upgrades

Upgrading the front forks can improve the Grom’s handling by reducing dive under braking and providing better feedback. Options include cartridge forks with adjustable compression and rebound damping, as well as drop-in fork springs with increased spring rates.

Rear Shock Upgrades

The stock rear shock on the Grom can be harsh and underdamped. Upgrading to an aftermarket shock with adjustable rebound and preload can significantly improve ride quality and control. Some shocks also offer remote reservoirs for fine-tuning compression damping.

Lowering Kit

Lowering the Grom can improve handling by lowering the bike’s center of gravity and increasing stability. Lowering kits typically include shorter fork springs and a lowering link for the rear shock.

Bar Riser Kit

Raising the handlebars can reduce strain on the rider’s wrists and arms. Bar riser kits come in various heights and can be adjusted to achieve a comfortable riding position.

Swingarm Upgrades

Upgrading the stock swingarm can improve handling by providing more rigidity and precision. Aftermarket swingarms are typically made of stronger materials and offer adjustable pivot points for fine-tuning wheelbase and geometry.

Wheels and Tires

Upgrading to larger wheels and tires can improve grip and stability, especially on rough or wet roads. Larger wheels also allow for the use of wider tires, which provide more surface area for contact with the road.
