What Problems Does the 2018 Honda Grom Have?
The 2018 Honda Grom is generally lauded for its exceptional reliability, a hallmark of Honda engineering. However, like any vehicle, owners have reported a few minor issues, though none are widespread or critical.
- Battery Life: Some owners occasionally report shorter than expected battery life, especially if the bike sits unused for extended periods. This is often mitigated with a battery tender during storage.
- Chain Maintenance: The small chain can require more frequent cleaning and lubrication than larger motorcycles, particularly if ridden in dirty conditions, leading to premature wear if neglected.
- Valve Adjustment: While not a frequent issue, some experienced riders suggest monitoring valve clearances as the mileage accumulates, though the SOHC engine is typically robust.
- Gear Indicator Issues: A very minor and less common complaint involves the gear indicator occasionally being imprecise or slow to update. This is rarely a functional problem but can be an annoyance.
- Brake Fade: Under very aggressive riding or prolonged heavy braking, some riders have noted minor brake fade, though for its intended urban use, the single disc brakes are usually more than adequate. Upgrading brake pads can address this for more spirited riding.
Recalls: For the 2018 model year, there have been no significant recalls reported by the NHTSA (National Highway Traffic Safety Administration) that are broadly impacting the vehicle's safety or operation. This speaks volumes about Honda's quality control for the Grom. Earlier model years (specifically 2014-2015) did have a recall related to the rear brake master cylinder, but this issue was addressed and is not applicable to the 2018 model.
Long-term Reliability Concerns:
The Honda Grom is renowned for its 'bulletproof' reliability and excellent long-term durability. The air-cooled 125cc engine is mechanically simple, making it highly robust and tolerant to varying conditions. With proper routine maintenance, including regular oil changes, chain care, and occasional valve checks, these bikes can easily last tens of thousands of miles. It's not uncommon for owners to report Groms running strong well past 30,000 or even 50,000 miles without major engine work. The primary "wear and tear" items will be consumables like tires, brakes, chain/sprockets, and spark plugs. Frame and suspension components are generally sturdy. Any significant long-term issues typically stem from neglect, improper modifications, or accidents rather than inherent design flaws. The lack of complex electronics also contributes to its ease of long-term ownership and troubleshooting.
How long will the 2018 Honda Grom last?
The 2018 Honda Grom, given its robust engineering and intended use, can reliably provide many years and tens of thousands of miles of service. Based on owner data and typical maintenance habits, it's common for Groms to reach 30,000 to 50,000 miles without requiring major engine overhauls, and often much more. With diligent maintenance—regular oil changes, chain adjustments, and proper storage—a Grom can easily last 10 to 15 years, or even longer, depending on usage frequency.
Long-term durability is a strong point. The air-cooled 125cc engine is notoriously simple and resilient, contributing to its longevity. Weaknesses over time are typically external components: faded plastics from sun exposure, rust on untreated steel parts in harsh climates, or worn-out suspension components after extensive use on rough roads. The electrical system and engine itself tend to be exceptionally durable. Owners who follow the maintenance schedule often find their Groms remain highly functional and fun for well over a decade.
What Technology & Safety Features are Included?
The 2018 Honda Grom, in keeping with its minimalist and fun-oriented design, focuses on essential features rather than extensive technological luxuries. It prioritizes rider engagement and simplicity.
- Built-in Tech & Entertainment:
- Digital LCD Instrumentation: The primary piece of "tech" is its clear, easy-to-read digital LCD dashboard. This display provides essential information, including a speedometer, odometer, dual trip meters, a fuel gauge, and a clock. It's backlit for good visibility in all conditions. There are no advanced infotainment screens, Bluetooth connectivity, or integrated sound systems, maintaining its "pure riding" ethos.
- Fuel Injection: The electronically controlled fuel injection system (PGM-FI) ensures precise fuel delivery, offering crisp throttle response, excellent fuel efficiency, and reliable starting in varying temperatures and altitudes.
- Driver-Assistance Features:
- The 2018 Honda Grom does not come equipped with advanced driver-assistance systems (ADAS) found in larger vehicles. Features like ABS (Anti-lock Braking System), traction control, or stability control are not standard or optional for this model year. Its lightweight and low-power nature typically makes such systems less critical for its intended urban environment. Some international versions or aftermarket kits might feature ABS, but it was not a factory option for the US 2018 Grom.
- Safety Features:
- LED Lighting: A significant safety feature is the modern LED headlight, which offers brighter, more focused illumination for enhanced visibility at night. The LED taillight also contributes to better rearward visibility for other road users.
- Disc Brakes: Equipped with hydraulic disc brakes on both the front and rear wheels, providing reliable stopping power. The front brake features a 220mm disc with a two-piston caliper, and the rear uses a 190mm disc with a single-piston caliper.
- Sturdy Chassis: A rigid steel mono-backbone frame provides a stable and predictable platform for handling, contributing to rider confidence and control.
- Inverted Front Fork: While primarily a performance feature, the inverted front fork enhances handling stability, which indirectly contributes to safety by offering better control.
- Compact Size & Maneuverability: The Grom's small dimensions and light weight make it exceptionally agile, allowing riders to navigate traffic and avoid obstacles more easily, which can be a key safety advantage in urban settings.
- Optional Features:
- From the factory, there were no significant optional tech or safety packages. Customization is primarily through aftermarket accessories, which range from performance upgrades (exhausts, suspension) to aesthetic enhancements (body panels, handlebar kits) and practical additions (luggage racks, heated grips).
- Crash-Test Ratings:
- Motorcycles, especially smaller models like the Grom, are not subjected to official crash-test ratings by organizations like the NHTSA or IIHS in the same way cars are. Safety relies more on the rider's protective gear, training, and awareness.
The Grom's safety aspects are rooted in its fundamental design: simplicity, maneuverability, and reliable basic components, rather than advanced electronic aids.

Recommendations:
For riders seeking pure miniMOTO fun and legendary reliability, the 2018 Honda Grom remains a top-tier choice. Its blend of simplicity, efficiency, and strong resale value is hard to beat.
The Kawasaki Z125 Pro is an equally strong contender, offering a very similar experience with a different aesthetic. If you prefer a slightly more aggressive look, it's an excellent alternative.
The Benelli TNT 135 is a great choice for those who desire a touch more power and a slightly different styling at a potentially lower price point, provided they are comfortable with a brand that has less historical reliability data in this specific segment compared to Honda.
Ultimately, the Grom is a well-rounded package; its rivals offer compelling alternatives primarily through styling or slight performance tweaks rather than fundamentally superior experiences.
Final Verdict: Is the 2018 Honda Grom a Good Motorcycle?
The 2018 Honda Grom is an ideal vehicle for a specific demographic of riders: new motorcyclists seeking an approachable entry point, urban commuters desiring ultimate maneuverability and economy, and experienced riders looking for a fun, playful 'garage addition' or pit bike. Its low seat height, light weight, and docile power make it incredibly forgiving and confidence-inspiring.
It is absolutely worth buying, especially as a used model. Given its minimal depreciation, a used 2018 Grom offers nearly the same value and experience as new but at a reduced cost. There's essentially only one 'trim' for the 2018 model, simplifying the choice. It excels for short commutes, weekend jaunts, or as a vehicle for learning advanced riding techniques in a low-stakes environment.
However, it's not for everyone. If your primary need is highway travel, carrying significant cargo, or two-up riding, the Grom's limitations will become apparent. For urban fun, incredible fuel economy, and legendary reliability, the 2018 Honda Grom is a resounding "yes." It delivers smiles per mile in spades and is a smart, economical choice for its intended purpose.
