The Bad

Key weaknesses of the 2018 Honda Grom include its limited top speed, making it unsuitable for highway travel, and its basic suspension, which can feel harsh on rough roads. The small fuel tank requires frequent refills, and its compact size, while a benefit, might be too cramped for larger riders or extended journeys. Power delivery is modest, which some might find inadequate.

2018 Honda Grom 125: Quick Overview

The 2018 Honda Grom 125, known for its fun and approachable nature, comes with a specific set of specifications that define its character:

  • Engine Options: The 2018 Honda Grom is powered by a single, highly reliable 125cc air-cooled, two-valve, SOHC, four-stroke engine. This fuel-injected powerplant is designed for efficiency and smooth, predictable power delivery, perfect for urban environments and casual riding. There are no other engine options available for this model year.

  • Horsepower: This compact engine produces approximately 9.7 horsepower at 7,000 RPM. While not designed for blistering speed, this output is perfectly adequate for the Grom's lightweight chassis, ensuring lively acceleration from a standstill and nimble handling around town.

  • Fuel Economy: One of the Grom's standout features is its phenomenal fuel economy. Owners consistently report mileage well over 100 MPG (miles per gallon), with figures often reaching 110-134 MPG depending on riding style and conditions. This makes it an incredibly economical choice for daily commuting and recreational riding.

  • 0-60 Times: The Honda Grom is not built for drag racing, and its 0-60 mph acceleration is quite leisurely. Achieving 60 mph typically takes anywhere from 10 to 12 seconds, or even longer depending on rider weight and road conditions. Its top speed is generally limited to around 55-60 mph, making it unsuitable for most highways.

  • Towing Capacity: As a compact motorcycle, the 2018 Honda Grom 125 is not designed for towing and therefore has no specified towing capacity. Any attempt to tow with this vehicle would be unsafe and is not recommended.

  • Trim-Level Features: The 2018 Grom primarily comes in one main trim, often referred to simply as the "Grom." Key features include a full digital LCD instrument panel providing speedometer, odometer, tachometer, fuel gauge, and clock. It boasts LED headlight and taillight for modern visibility and style. It features an inverted fork, a monoshock rear suspension, and disc brakes both front and rear. A significant optional feature for the 2018 model year was the availability of an Anti-lock Braking System (ABS) on certain colorways, providing enhanced safety during braking. The compact, modular frame and exposed engine also lend themselves well to aftermarket customization, which is a huge draw for owners.

What Problems Does the 2018 Honda Grom 125 Have?

The 2018 Honda Grom 125, while generally very reliable due to Honda's excellent engineering, has a few frequently reported issues and considerations, though fewer than earlier generations. The first generation Groms (2014-2015) experienced some specific problems, most notably issues with the stator and occasional rough idling or stalling. Honda addressed many of these with subsequent model revisions.

For the 2018 model, which is part of the second generation, significant recalls or widespread, catastrophic failures are uncommon. However, minor issues can still arise. Owners sometimes report quirky fuel gauge readings, where the gauge may seem inconsistent or not entirely linear, leading to uncertainty about the exact fuel level remaining. Another common observation is related to the basic nature of its suspension. While adequate for smooth urban roads, the non-adjustable forks and basic rear monoshock can feel somewhat harsh or "bouncy" over rougher pavement or potholes, leading some riders to seek aftermarket suspension upgrades for improved comfort and handling.

Long-term reliability is generally excellent, given proper maintenance. The 125cc engine is robust and known for lasting tens of thousands of miles with regular oil changes and valve adjustments. Issues such as electrical gremlins or major engine component failures are rare. However, like any small displacement, air-cooled engine, consistent high-RPM riding or neglecting maintenance can lead to premature wear. Chain and sprocket wear is typical for any chain-driven motorcycle, and regular inspection and lubrication are crucial. Some riders who push their Groms hard or heavily modify them might experience accelerated wear on clutch components or tires. Overall, the 2018 Grom maintains Honda's reputation for dependability, with most reported problems being minor annoyances or related to the vehicle's inherent design compromises for affordability and size rather than manufacturing defects.

How long will the 2018 Honda Grom 125 last?

Based on owner data and typical maintenance habits, a 2018 Honda Grom 125 can easily provide 30,000 to 50,000 miles of service, often lasting 10-15 years or more with diligent care. Honda's 125cc engine is renowned for its durability. Key to long-term reliability is regular oil changes, valve clearance checks, and chain maintenance. Weaknesses over time can include typical wear items like clutch plates, brake pads, tires, and potentially suspension components for riders seeking a more refined ride. The basic electrical system is generally robust, but connections can sometimes degrade in harsh environments. Frame integrity is excellent, and rust is rarely an issue if stored properly. Overall, the Grom is a remarkably durable machine, forgiving of casual use, but thrives with attentive maintenance, ensuring many years of enjoyable riding.

What Technology & Safety Features are Included?

The 2018 Honda Grom 125, true to its mini-moto philosophy, prioritizes simplicity and riding enjoyment over a lavish suite of electronics. However, it still incorporates modern, essential features.

Built-in Tech and Entertainment: The primary piece of built-in technology is its contemporary, full-digital LCD instrument cluster. This compact display efficiently provides riders with crucial information at a glance, including a digital speedometer, odometer, two trip meters, a fuel gauge, a clock, and a prominent tachometer. While there are no integrated entertainment features like audio systems or smartphone connectivity, its focus is purely on the riding experience. The lighting system features a modern LED headlight and taillight, offering excellent visibility and a sleek appearance, significantly improving upon traditional incandescent bulbs.

Driver-Assistance and Safety Features: In terms of driver-assistance, the Grom is a straightforward motorcycle with minimal electronic aids beyond the optional braking system. It does not include advanced features like traction control, multiple ride modes, or stability control, which are typically found on larger, more expensive motorcycles. The 2018 model did, however, offer a significant safety enhancement: an optional Anti-lock Braking System (ABS). This single-channel ABS (typically on the front wheel) helps prevent wheel lock-up during hard braking, especially on slippery surfaces, significantly boosting rider confidence and safety. This was a notable upgrade, as many mini-motos in its class did not offer ABS. The braking system consists of a single disc brake at the front and a single disc brake at the rear, providing adequate stopping power for its size and speed.

Crash-Test Ratings: It is important to note that motorcycles, including the Honda Grom 125, are not subjected to the same standardized crash-test ratings (like NHTSA or IIHS) as passenger cars. Their safety is more commonly assessed through rider training, protective gear, and the effectiveness of braking systems like ABS. The Grom's lightweight and agile nature, combined with its low top speed, inherently contribute to a lower risk profile compared to higher-performance motorcycles in certain types of accidents, although rider skill remains paramount.

How Does the 2018 Honda Grom 125 Compare to Other Motorcycle?

The 2018 Honda Grom 125 occupies a unique niche in the mini-moto segment, but it does face several key rivals, primarily the Kawasaki Z125 Pro and the Benelli TNT 135.

Performance: The Grom's 9.7 horsepower 125cc engine provides sufficient pep for city streets and joyriding, but it's not a speed demon. The Kawasaki Z125 Pro offers very similar performance, also featuring a 125cc single-cylinder engine with comparable horsepower, making it a direct competitor in terms of acceleration and top speed. The Benelli TNT 135, however, often edges out both with its slightly larger 135cc engine and a bit more horsepower (around 11.3 hp), giving it a slight performance advantage, particularly at higher speeds. None of these are highway-capable.

Features: All three mini-motos offer basic digital instrumentation, disc brakes, and LED lighting. The 2018 Grom offered optional ABS, a significant safety feature that the Z125 Pro typically lacked in that model year. The Benelli TNT 135 features an inverted fork, similar to the Grom, and often comes with a more aggressive aesthetic. Customization potential is high for all three, with vast aftermarket support.

Reliability: Honda is synonymous with reliability, and the Grom lives up to this reputation, offering robust engineering and predictable long-term durability. Kawasaki's Z125 Pro is also highly reliable, benefiting from Kawasaki's strong manufacturing standards. The Benelli TNT 135, while generally dependable, is a newer entrant and some owners report slightly more varied experiences regarding build quality or parts availability compared to its Japanese counterparts. However, all three are generally considered durable for their class.

Price: New, the 2018 Grom was priced around $3,349-$3,549. The Kawasaki Z125 Pro was typically priced very similarly, often within a hundred dollars. The Benelli TNT 135 usually came in at a slightly lower price point, making it an attractive value proposition. In the used market, the Grom tends to hold its value exceptionally well, often fetching prices comparable to new models, while the Z125 Pro also maintains good resale. The Benelli's resale value is decent but might not be as strong as the two Japanese brands.

Alternatives: For someone prioritizing pure fun, customization, and absolute reliability, the Honda Grom 125 remains a top choice. The Kawasaki Z125 Pro is an excellent "similar alternative" offering a very comparable experience with slightly different styling. If a bit more power and a lower entry price are appealing, the Benelli TNT 135 could be considered a "better alternative" for performance-oriented riders on a tighter budget. For those wanting a more classic mini-bike feel, the Honda Monkey 125 (though not a direct 2018 rival as it was released later in 2018/2019) is another premium Honda option that offers similar urban fun with retro styling.

Final Verdict: Is the 2018 Honda Grom 125 a Good Motorcycle?

The 2018 Honda Grom 125 is an ideal vehicle for urban commuters, new riders learning the ropes, and anyone seeking an incredibly fun, customizable, and economical second bike. Its low running costs, legendary Honda reliability, and nimble handling make it perfect for navigating congested city streets or simply enjoying spirited short rides. It's not suited for highway travel or long-distance touring due to its limited top speed and small size. It is absolutely worth buying, especially as a used model. Given its low depreciation, a well-maintained used 2018 Grom, particularly one with optional ABS, offers fantastic value. While new models offer full warranty, the robust nature of the Grom means a used model with a clear service history can be a smarter financial decision, providing nearly the same enjoyment and longevity at a lower upfront cost. The ABS trim is recommended for enhanced safety.
