Honda MSX 125 Grom [2013-2016]: A Timeless Urban Companion

Introduction

The Honda MSX 125 Grom, sold globally between 2013 and 2016, is a motorcycle that defies categorization. Part mini-moto, part urban warrior, and entirely a riot to ride, the Grom carved out a niche as a lightweight, approachable, and endlessly customizable machine. Designed for city streets but capable of sparking joy on backroads, this pint-sized Honda became a cult classic—and after swinging a leg over one, it’s easy to see why.

Let’s dive into what makes this generation of the Grom a standout, even years after its debut.

The Riding Experience: Small Bike, Big Grins

Engine and Performance

At the heart of the Grom is a 124.9cc air-cooled single-cylinder engine, producing 9.7 HP (7.2 kW) at 7,000 RPM and 10.9 Nm (8.0 lb-ft) of torque at 5,500 RPM. On paper, these numbers won’t set your hair on fire, but the Grom’s magic lies in how it delivers its power. The fuel-injected mill is buttery smooth, with a linear throttle response that makes it perfect for darting through traffic or practicing low-speed maneuvers.

The 4-speed gearbox is a highlight. Shifts are crisp, and the clutch is featherlight—ideal for new riders. While top speed hovers around 90 km/h (56 mph), the Grom thrives in urban zones where speeds rarely exceed 60 km/h (37 mph). Fuel efficiency is stellar at 1.76 L/100 km (133.65 mpg), meaning you’ll spend more time riding than visiting gas stations.

Test Ride Takeaway:
Twisting the throttle in first gear delivers a surprisingly punchy launch, and the engine’s willingness to rev makes even short commutes feel like an adventure. It’s not a highway cruiser, but for city dwellers, the Grom’s performance is Goldilocks-approved: just right.

Chassis and Handling

Weighing just 102 kg (225 lbs) with fluids, the Grom feels like an extension of your body. The steel frame and 31mm inverted front fork provide a planted feel, while the 1199mm (47.2-inch) wheelbase strikes a balance between agility and stability.

The 12-inch wheels (120/70 front, 130/70 rear) contribute to its go-kart-like handling. Cornering is intuitive, and the low 754mm (29.7-inch) seat height inspires confidence for riders of all sizes. Suspension travel—118mm (4.6 inches) up front and 70mm (2.8 inches) at the rear—soaks up potholes better than expected, though rough roads will remind you this is a budget-friendly machine.

Braking:
Early models used a 220mm front disc with a two-piston caliper and a 190mm rear drum, but later years upgraded to a rear disc. The front brake offers solid bite, while the rear requires a deliberate stomp. ABS wasn’t an option, so smooth inputs are key.

Design and Features: Minimalism with Attitude

The Grom’s design is a masterclass in simplicity. Its compact dimensions—1760mm (69.3 inches) long and 775mm (30.5 inches) wide—give it a toy-like appearance, but the fit and finish are unmistakably Honda. Colors like Pearl White, Metallic Black, and Rally Red pop in sunlight, and the exposed frame invites customization.

The analog speedometer is basic but legible, and the lack of a tometer encourages you to ride by feel. The upright riding position and wide handlebars offer comfort for hour-long rides, though taller riders might crave more legroom.

Competition: How the Grom Stacks Up

The 125cc segment is fiercely competitive. Here’s how the Grom compares to its rivals:

1. Kawasaki Z125 Pro

• Similar weight and power figures, but the Z125’s styling is sharper and more aggressive.
• The Grom counters with a slightly more comfortable seat and a larger aftermarket support network.
• Verdict: Tie on performance, but Grom wins on customization potential.

2. Yamaha YZF-R125

• A sportier option with a liquid-cooled engine and 15 HP.
• Far pricier and heavier (138 kg / 304 lbs), making the Grom a better urban companion.
• Verdict: YZF-R125 for speed; Grom for fun-per-dollar.

3. KTM 125 Duke

• The Duke’s 15 HP and premium suspension outclass the Grom on technical roads.
• However, the KTM costs nearly double and lacks the Grom’s playful vibe.
• Verdict: Duke for serious riders; Grom for everyone else.

The Grom’s Edge:
No competitor matches its aftermarket ecosystem. From stunt cages to big-bore kits, the Grom is a blank canvas—a quality that keeps it relevant years after purchase.

Maintenance: Keeping Your Grom Happy

Ownership is refreshingly straightforward, but here are key tips to ensure longevity:

1. Oil Changes

• Use SAE 10W-30 (900ml without filter, 1L with filter).
• Replace every 4,000 km (2,500 miles).

2. Chain Care

• The 106-link chain requires regular cleaning and lubrication. Adjust tension to 20-30mm (0.8-1.2 inches) of free play.

3. Valve Adjustments

• Check every 4,000 km (2,500 miles):
• Intake: 0.10mm (0.004 inches)
• Exhaust: 0.17mm (0.007 inches)

4. Brake Fluid

• Replace DOT 4 fluid every two years or if sponginess develops.

5. Tire Pressure

• Front/Rear: 2.0 bar (29 psi). Stick to 12-inch tires for optimal handling.

Common Upgrades:
- Exhaust: Swap the stock muffler for a lighter, throatier aftermarket option.
- Suspension: Upgrade shocks for heavier riders or aggressive riding.
- Styling: LED lights, bar-end mirrors, and custom decals personalize your Grom.
