Introduction
The honda grom stretch kit is one of the most popular mini motorcycles in the world, known for its lightweight frame, stylish looks, and versatile performance. Since its launch, the Grom has captured the hearts of both beginners and experienced riders who want an affordable, fun, and reliable bike. What makes the Honda Grom even more exciting is the limitless customization potential.

Among the most popular modifications is the Honda Grom stretch kit. This upgrade allows riders to stretch the swingarm of the bike, giving it a longer, lower, and more aggressive stance. For many enthusiasts, this is not just about looks—it’s also about handling, stability, and performance. In this article, we’ll dive deep into everything you need to know about the Honda Grom stretch kit, its benefits, installation, costs, and whether it’s the right choice for your ride.
What is a Honda Grom Stretch Kit?
A stretch kit is an aftermarket modification designed to extend the swingarm of a motorcycle. On the Honda Grom, the stretch kit pushes the rear wheel further back, creating a longer wheelbase. This modification changes both the aesthetic appeal and riding dynamics of the bike.
The kit typically includes:
- Extended swingarm or adjustable extension plates
- Mounting brackets and hardware
- Chain extension or replacement links
- Optional add-ons like rear lowering links
Stretching a Honda Grom gives it a drag-bike inspired look, making it appear more aggressive and customized compared to the stock model.
Why Do Riders Install a Stretch Kit on Their Honda Grom?
1. Aesthetic Appeal
The first reason most riders opt for a Honda Grom stretch kit is the unique look. A stretched Grom sits lower, longer, and more aggressive, mimicking the appearance of sportbikes and drag racers. Many owners use stretch kits to showcase their custom paint jobs, aftermarket wheels, and upgraded exhausts.
2. Improved Stability
By extending the swingarm and wheelbase, the Honda Grom becomes more stable at higher speeds. While the bike is not designed to be a highway cruiser, the additional length reduces wobble and provides more confidence during straight-line riding.
3. Better Traction
A stretched wheelbase improves weight distribution, especially during acceleration. This helps prevent unwanted wheelies and provides better traction on the rear tire.
4. Personalization and Uniqueness
The Grom community thrives on individuality. Riders want their bike to stand out, and a stretch kit is one of the most noticeable customizations. Pairing it with other mods like lowered suspension, custom wheels, or aftermarket fairings makes a Grom truly one of a kind.
Types of Honda Grom Stretch Kits
1. Fixed-Length Stretch Kits
These kits extend the swingarm by a specific measurement, usually ranging from 4 inches to 12 inches. Once installed, the stretch length is permanent.
2. Adjustable Stretch Kits
Adjustable stretch kits allow flexibility, enabling riders to adjust the wheelbase according to their preference. For example, an adjustable kit may provide a range of 4–8 inches of extension.
3. Bolt-On Extension Plates
These are budget-friendly options that bolt onto the stock swingarm to create an extended length. They are easier to install compared to full swingarm replacements.
How Much Does a Honda Grom Stretch Kit Cost?
The cost of a stretch kit depends on the type, brand, and materials used.
- Basic bolt-on extension plates: $100–$200
- Mid-range adjustable stretch kits: $250–$500
- High-end custom swingarms: $600–$1000+
Additional costs include a longer chain, labor (if not installing yourself), and possible suspension modifications. On average, a full stretch and customization project may cost between $400–$1200.

Is a Stretch Kit Right for You?
A Honda Grom stretch kit is perfect for riders who want a unique, aggressive look and improved straight-line stability. However, if you enjoy sharp cornering, nimble maneuverability, or track riding, stretching might not be ideal since it compromises tight handling.
If your goal is to build a show bike, stunt machine, or drag-style Grom, a stretch kit is a must-have. If you prefer commuting or city riding with lots of turns, you may want to keep the stock swingarm.
Maintenance Tips for Stretched Honda Groms
- Regularly check chain tension – Longer chains need frequent adjustments.
- Inspect bolts and hardware – Vibrations can loosen aftermarket parts.
- Maintain suspension – Adjust preload and damping for the stretched setup.
- Check tire wear – Extended wheelbase can change tire load distribution.
Proper maintenance ensures safety and extends the life of your customization.

The Honda Grom community is massive, with countless online forums, Facebook groups, and Instagram pages dedicated to modified Groms. Stretch kits are a centerpiece of this culture, often featured in bike shows and stunt events. Riders love showcasing their unique builds, trading tips, and inspiring others with their stretched Grom designs.
Events like Grom Meets or local bike shows often highlight stretched Groms with flashy paint jobs, fat tires, and LED lights. If you’re looking to connect with other enthusiasts, joining a Grom community will give you valuable insights and inspiration.
Conclusion
The Honda Grom stretch kit is one of the most popular and transformative modifications you can make to your bike. It provides a sleek, aggressive stance while enhancing stability and traction. However, it does come with trade-offs, such as reduced cornering agility and additional maintenance.
For riders who want their Grom to stand out from the crowd, a stretch kit is an excellent investment. Whether you choose a bolt-on plate or a full custom swingarm, stretching your Grom opens the door to a world of personalization and performance upgrades.
At the end of the day, the Honda Grom is all about fun, freedom, and self-expression—and a stretch kit perfectly captures that spirit
