The **Honda Grom MSX125 (MLHJC7516J5011317, Model Years 2017 2020)** represents the pinnacle of modern streetfighter design, blending raw aggression with Honda s legendary precision engineering. This compact, high-performance motorcycle features a **straight-tube, single-crankshaft frame chassis (50100-K26-B00)**, a signature choice that delivers an uncompromising riding position and a direct, responsive feel. The **aluminum twin-spar frame** is not only lightweight but also engineered for rigidity, ensuring optimal power transfer and handling dynamics. The **semi-double-cradle design** enhances durability while maintaining a minimalist aesthetic, with clean, angular lines that emphasize its sporty, no-nonsense character. The **SLVG (Super Lightweight Grom)** designation underscores its commitment to agility, with a dry weight of just **216 lbs (98 kg)**, making it one of the lightest production motorcycles in its class.
At its core, the Grom is powered by Honda s **124cc, air-cooled, single-cylinder engine**, a refined evolution of the iconic MSX platform. This compact powerplant delivers **13.8 horsepower and 10.6 lb-ft of torque**, enough to propel the bike from 0-60 mph in under 4 seconds while maintaining a smooth, linear power delivery. The engine s **single overhead camshaft (SOHC)** and **desmodromic valve actuation** ensure precise timing and reliability, while the **wet-sump lubrication system** keeps maintenance simple. The **6-speed transmission** is paired with a **chain final drive**, offering a balance of efficiency and durability, though the bike s lightweight nature makes it equally at home with a quick-shifting rider or a casual cruiser.
The Grom s **front suspension** consists of **31mm inverted Showa SFF-BP (Super Lightweight Front Fork)** with adjustable preload and rebound damping, providing a firm yet compliant ride for both city commuting and spirited cornering. The **cast aluminum swingarm** and **single-sided rear shock** (with adjustable preload and rebound) complete the suspension setup, ensuring the bike remains planted under hard acceleration or aggressive braking. The **front disc brake** features a **single 298mm petal-style rotor** with a **two-piston caliper**, delivering strong stopping power in proportion to the bike s size, while the **rear brake** is a **single 220mm disc with a single-piston caliper**, offering adequate modulation for everyday use.
The Grom s **ergonomics** are designed for efficiency and control, with a **low, aggressive riding position** that places the rider s weight over the front wheel for enhanced stability. The **ergonomic seat** is contoured for comfort during short rides but encourages an upright posture for better visibility and control. The **full fairing** wraps around the bike in a sharp, angular design, reducing wind noise while maintaining an open, unobstructed view of the road. The **LED headlight** and **LED taillight** provide modern illumination without adding unnecessary bulk, while the **digital instrument cluster** features a **speedometer, odometer, fuel gauge, and trip meters**, all housed in a sleek, minimalist display.
Underneath its aggressive exterior, the Grom is built for **durability and practicality**, with a **steel subframe** supporting the engine and a **galvanized steel exhaust system** that balances performance with longevity. The **fuel tank capacity of 1.7 gallons** offers a respectable range for daily riding, while the **removable seat** and **under-seat storage** provide additional convenience. The bike s **no-frills approach** from its **bare-bones handlebars** to its **minimalist footpegs** reinforces its identity as a **pure, unadulterated streetfighter**, designed for riders who prioritize performance, maneuverability, and a raw, unfiltered riding experience.
Whether navigating tight city streets, carving through winding roads, or simply cruising with effortless ease, the Honda Grom MSX125 stands as a testament to Honda s ability to distill performance into its most essential form. Its **straight-tube frame chassis (50100-K26-B00)** ensures a neutral, responsive ride, while its **lightweight construction and precise engineering** make it a joy to own and operate. For riders seeking a motorcycle that is as much about attitude as it is about capability, the Grom delivers an unmatched blend of style, agility, and Honda reliability.

- The **air-cooled engine** can be noisy, especially at idle.
