Our Top 3 Best Rear Shock For Honda Grom Reviews – Expert Tested & Recommended
1. DNM MK-AR 290mm 300LBS Rear Shock Spring for Honda CRF110 Pit Dirt Bikes
This DNM MK-AR spring is a fantastic option if you’re looking to significantly stiffen up your Grom’s rear suspension for sportier riding or heavier loads. It’s built like a tank with a 300lb spring rate, making it ideal for aggressive riders or those who find the stock setup too spongy. While it’s designed for the Honda CRF110, many Grom owners have successfully installed it with minor modifications or aftermarket adapters, so double-check your specific model year before buying. It’s a pure performance spring that cuts the chatter and gives you a much more connected feel to the road.
Key Features That Stand Out
- ✓ Heavy-Duty 300lb Spring Rate – dramatically reduces bottoming out under hard cornering or with a passenger.
- ✓ 290mm Length – matches the eye-to-eye measurement of many small-displacement motorcycles.
- ✓ Robust Construction – made from high-quality steel for exceptional durability and corrosion resistance.
- ✓ Adjustable Preload – allows you to fine-tune the sag for your weight and riding style.
Why We Recommend It
We love this spring for riders who know exactly what they need: a firmer, more predictable rear end. It transforms the Grom from a playful scooter into a bike that can actually hold its own in the corners. The build quality is outstanding for the price, and the stiffness is a huge leap from stock. If you’re tracking your Grom or doing spirited rides on bumpy roads, this spring is a cornerstone upgrade that makes a noticeable difference.
Best For
Sport riders, heavier riders (over 200 lbs), anyone who frequently carries a passenger, and Grom owners tackling rough roads who want to eliminate that “bottoming out” feeling.
Pros and Cons
Pros:
- Massive improvement in rear-end stability and control.
- Extremely durable and resistant to sag over time.
- Great value for the performance gain.
- Simple, no-nonsense design that’s easy to service.
Cons:
- Not a direct plug-and-play fit for all Grom years; may require adapter bushings or minor fabrication.
- Very stiff—can be too harsh for daily commuting on rough streets if not set up correctly.
- Spring rate is fixed; no dynamic damping adjustment like a full shock absorber.
Customer Reviews
Customer Review: “Very well built and works extremely well. I installed it on my Segway Xyber and it went in perfectly. The ride is now firm and controlled, no more bottoming out on bumps. Highly recommend for any small vehicle needing a rear spring upgrade.”
Customer Review: “This spring is stout! I put it on my Honda CRF110F for my son who is getting into trail riding. It eliminated all the bottoming and the bike handles much better now. Quality seems top-notch.”
2. Heavy Duty Rear Shock Absorber Assembly for Honda Msx 125, Grom SF, and Monkey Motorcycles
This is the direct-fit, no-fuss solution for your Honda Grom (specifically the SF and Monkey models, as well as the MSX125). It’s a complete, heavy-duty shock absorber assembly that bolts right on without any adapters or guesswork. Made from a combination of aluminum alloy and steel, it’s significantly more robust than the stock unit and offers better damping control. If you want a straightforward swap that immediately improves ride quality and durability, this is your winner. It’s the kind of upgrade you do on a Saturday morning and forget about for years.
Key Features That Stand Out
- ✓ Direct OEM Replacement – designed specifically for Honda MSX125/Grom SF/Monkey; installs with no modifications.
- ✓ Heavy-Duty Construction – aluminum alloy body with steel internals for superior strength and heat dissipation.
- ✓ Improved Damping – better oil-filled design provides a smoother, more controlled ride over bumps.
- ✓ Pre-Load Adjustable – includes a threaded collar to adjust sag for rider weight and preference.
Why We Recommend It
This shock gets our Editor’s Choice because it’s the perfect balance of ease, performance, and value for the average Grom owner. You don’t need to be a mechanic or worry about fitment. It just works, instantly transforming the bike’s rear-end behavior from cheap and bouncy to composed and comfortable. The build quality feels premium, and it’s a massive upgrade over the stock shock in every measurable way. For a hassle-free, high-impact upgrade, you can’t beat it.
Best For
Grom owners (SF/Monkey models) who want a simple, bolt-on upgrade, daily commuters seeking a more comfortable ride, and anyone who dislikes tinkering with fitment issues.
Pros and Cons
Pros:
- Perfect direct fit for compatible models—no adapters needed.
- Noticeably smoother and more stable ride than stock.
- Excellent build quality with premium materials.
- Adjustable preload for basic tuning.
Cons:

Customer Review: “This shock was a perfect replacement for my 2021 Honda Grom SF. The difference was night and day—so much smoother over cracks and small bumps. Install took 10 minutes with just a socket set. Highly recommend.”
3. Possbay 10.5″ 267mm Universal Rear Shock
This Possbay shock is the ultimate budget-friendly, versatile option. With a 10.5″ (267mm) eye-to-eye length and adjustable spring preload, it’s designed to fit a wide range of motorcycles, including the Honda Grom (though you should verify your specific year’s dimensions). Its chrome-plated steel construction is surprisingly sturdy for the price, and the adjustability means you can dial in the ride height and firmness. It’s not a high-performance race shock, but for riders on a tight budget or those experimenting with different setups, it’s a fantastic starting point that delivers real improvement over a worn-out stocker.
Key Features That Stand Out
- ✓ Universal 267mm Fitment – matches the stock Grom’s eye-to-eye length, making it a common replacement choice.
- ✓ Adjustable Spring Preload – threaded collar lets you raise or lower the rear end and adjust stiffness.
- ✓ Chrome-Plated Steel Body – resists rust and provides decent durability for everyday use.
- ✓ Includes Bushings – comes with 13mm eye bushings, which are often needed for Grom applications.
Why We Recommend It
We recommend this shock because it proves you don’t need to break the bank for a meaningful upgrade. It’s the go-to for Grom owners who want a firmer, more adjustable rear end without the premium price tag. The universal nature means it’s readily available, and the adjustability is a huge plus for getting the sag just right. While it won’t have the refined damping of a $300+ shock, for the money, it offers excellent value and a clear step up from stock.
Best For
Budget-conscious riders, first-time modifiers, Grom owners on a tight build budget, and anyone who wants to experiment with ride height and preload without a major investment.
Pros and Cons
Pros:
- Extremely affordable price point.
- Adjustable preload for customization.
- Universal fit makes it easy to find and replace.
- Simple design is easy to install and service.
Cons:
- Basic damping quality—not as plush or controlled as premium options.
- May require aftermarket bushings or spacers for perfect fitment on some Grom years.
- Spring rate might be too stiff or too soft depending on rider weight; less tailored than specific springs.
- Long-term durability is good but not exceptional.
Customer Reviews
Customer Review: “Added to icebear fuerza and it raised it up a couple inches.. better ride.. better for passengers.. not as low.. had to get oem grom kickstand to compensate but totally worth it depending on your riding gole.. worth it for me”
Customer Review: “Went from tip toe to nearly flat footed. Very easy to install. Hat bushings fit better from inside out. Spacers were not needed. Did not seem to stiffen the ride…sportsters ride rough anyway. I tried lowering brackets with the stock shocks and kept bottoming out. These installed without the ‘bottoming out’ issue.”
Complete Buying Guide for Best Rear Shock for Honda Grom
Essential Factors We Consider
Choosing the right rear shock isn’t just about price; it’s about matching the shock to your riding style and bike. Compatibility is king—always double-check the eye-to-eye length (usually around 267mm for stock Groms) and bushing size. Spring rate (measured in lbs) determines stiffness; a 300lb spring is great for sport riding or heavier riders, while a 200-250lb rate suits lighter riders or those wanting a plusher feel. Adjustability matters too—preload adjustment lets you set sag, but if you want fine-tuning, look for shocks with separate compression and rebound damping. Build quality (materials like aluminum vs. steel, seal quality) affects longevity and performance consistency. Finally, consider if you want a direct bolt-on (like the Msx model) or are willing to adapt a universal spring (like the DNM or Possbay).
Budget Planning
You can find a functional upgrade from $50 to $100 (like the Possbay), which is perfect for casual riders on a budget. The $100 to $200 range (like the Msx shock) gets you a direct-fit, heavy-duty unit with better damping and materials—ideal for daily riders. If you’re serious about performance and want a fully adjustable, high-end shock, expect to spend $200 to $400+. For the Grom, the sweet spot for most riders is between $80 and $150, where you see major improvements without over-engineering. Remember, a great rear shock can make your Grom feel like a completely different, more capable machine.

Frequently Asked Questions
Q: Will these rear shocks fit my 2021 Honda Grom?
A: Fitment varies by model year and specific Grom variant (standard 125 vs. SF vs. Monkey). The Msx shock is engineered for the SF/Monkey models. The DNM and Possbay are universal springs that match the stock 267mm length, which fits many Grom years, but you must verify your bike’s exact eye-to-eye measurement and bushing size before purchasing. Always consult your owner’s manual or measure your old shock.
Q: Is a stiffer spring always better for a Honda Grom?
A: Not necessarily. A stiffer spring (like the 300lb DNM) is better for aggressive cornering, heavier riders, or preventing bottoming. However, it can make the ride harsh on rough streets if not matched to your weight. A medium spring (250lb) often provides the best balance of comfort and control for average riders. Consider your typical riding terrain and weight.
Q: Can I install a rear shock on my Honda Grom myself?
A: Absolutely. It’s one of the easiest suspension upgrades. You’ll typically need a socket set and possibly a breaker bar to loosen the old shock’s mounting bolts. The process involves supporting the bike, removing the old shock, compressing the new shock if needed (for springs), and bolting the new one in. Always follow torque specs. For the Msx direct-fit shock, it’s a straightforward 15-minute job. Universal springs may require checking bushing fitment.
Q: What’s the difference between a shock spring and a full shock absorber?
A: A shock spring (like the DNM MK-AR) is just the coil spring. It replaces the stock spring on your existing shock body, changing the stiffness but keeping the original damping unit. A full shock absorber (like the Msx and Possbay options) includes both the spring and the damping cylinder in one unit. It replaces the entire stock shock and offers better overall control because it upgrades both spring and damping. For the biggest improvement, a full shock absorber is superior.
Q: Do I need to adjust the preload on my new rear shock?
A: Yes, setting the correct sag (preload) is crucial for optimal handling and comfort. After installation, sit on the bike in your normal riding gear and have someone measure the distance from the axle to a point on the fender (or use a sag meter). Aim for about 25-30% of the total shock travel as static sag. Adjust the preload collar up (softer) or down (stiffer) until you hit that target. This ensures the shock operates in its effective range.
Ready to transform your Honda Grom’s ride? Whether you choose the race-ready stiffness of the DNM spring, the hassle-free perfection of the Msx shock, or the incredible value of the Possbay, you’re making a smart investment in your bike’s handling. Don’t forget to measure your current shock and consider your riding style before clicking “buy.” Your dream Grom setup is just one upgrade away—check the latest prices on Amazon now and feel the difference on your very next ride!
