This is a complete audio analysis based on the official specifications, environmental specifications, and size diagrams of Honda's full-fledged 123cc sports moped, the "GROM (Model: 8BJ-JC92 / Engine Model: JC92E)."

This audio thoroughly explores the capabilities and practicality of this popular model, equipped with a 123cm³ air-cooled four-stroke OHC single-cylinder engine and a constant-mesh 5-speed return transmission.

[GROM Lineage, Production Base, and Environmental Compliance Background]
Manufactured by "Thai Honda Co., Ltd." in Thailand, and imported and distributed domestically by Honda Motor Co., Ltd., this is a global model.

The 8BJ-JC92 model complies with the 2020 (Heisei 32) exhaust gas regulations and the 2016 (Heisei 28) noise regulations through engine improvements, the adoption of a three-way catalytic converter (monolith), a sealed blow-by gas recirculation system, a fuel evaporation gas suppression system, and an on-board fault diagnosis system.

Furthermore, thorough recycling design and reduction of environmentally harmful substances have been implemented based on the 3R pre-evaluation system since 1992.

[Officially Confirmed Main Specifications - The Essence of the JC92E Four-Stroke Engine and Body Design]
The 123cm³ air-cooled four-stroke OHC single-cylinder engine, with its long-stroke setting of 50.0mm bore x 63.1mm stroke and compression ratio of 10.0, delivers a maximum output of 7.4kW (10PS) at 7,250rpm and a maximum torque of 11N·m (1.1kgf·m) at 6,000rpm.
Combining FI (PGM-FI) and a 5-speed return transmission (1st gear 2.846 to 5th gear 0.843), it achieves a WMTC mode fuel efficiency of 67.8km/L (Class 1, 1 rider) and a constant speed fuel efficiency of 63.5km/L at 60km/h (2 riders). The backbone frame chassis, measuring 1,760mm in length, 720mm in width, and 1,015mm in height, with a wheelbase of 1,200mm, a caster angle of 25°00′, and a trail of 81mm, boasts a light vehicle weight of 103kg.

[Packaging of Footing, Riding Position, and Touring Practicality]
The seat height is a low 761mm, and the minimum turning radius is just 1.9m. A minimum ground clearance of 180mm is ensured, and the Gaiety Red model, which comes standard with an under cowl, has the same minimum ground clearance (based on the exhaust pipe) and vehicle weight.

Equipped with a 6.0L tank compatible with unleaded regular gasoline, it provides reliable support for everyday use and long-distance touring with its theoretically impressive cruising range exceeding 400km.

[Suspension, Brake Structure, and Mechanism Functionality]
The front features a high-rigidity telescopic inverted suspension, and the rear employs a swingarm suspension.

The 12-inch wide tires (front 120/70-12 51L, rear 130/70-12 56L) and front and rear hydraulic disc brakes (front only equipped with ABS) support a light and secure ride.

[Professional's One-Point Advice]
◆Biggest Appeal:
The ultra-lightweight body of 103kg, low seat height of 761mm, the joy of driving the 5-speed manual transmission, and the ultimate fuel economy of 67.8km/L in WMTC mode.

◆Most Important Points to Note:
Because it is a 123cm³ (Class 2 moped), it cannot be used on highways. The ABS is only equipped on the front. The compact living space due to the short wheelbase (1,200mm) is a point you should be aware of before purchasing.
