Overview

Introducing the 2015 Honda Grom 125, a pint-sized powerhouse that has taken the motorcycle world by storm. Positioned in the sport category, this agile mini-bike delivers big fun without the hefty price tag, making it an ideal choice for both novice riders and seasoned enthusiasts looking for a zippy machine to navigate urban landscapes. With its playful aesthetics and a reputation for reliability, the Grom has become a cult favorite, often seen buzzing through city streets or parked at cafes, where its distinctive style always turns heads. At the heart of the Grom 125 lies a spirited 124.9 cc single-cylinder, four-stroke engine, designed to deliver an exhilarating ride. With a compression ratio of 9.3:1 and a bore and stroke of 52.4 x 57.9 mm, this engine achieves a balance of power and efficiency, making it perfect for zipping through traffic or enjoying a leisurely ride in the park. The air-cooled setup keeps things simple and lightweight, while the PGM-FI fuel injection ensures smooth throttle response and reliable performance. Coupled with a 4-speed gearbox and a chain final drive, the Grom is engineered for nimble acceleration, easily maneuvering through tight corners with an impressive rake of 25 degrees and a trail of 81 mm. The Grom 125's design is not just about performance; it's packed with features that enhance the riding experience. An electric starter adds convenience, while its lightweight frame, weighing only 102.1 kg (225 pounds) with fluids, allows for easy handling. The front suspension boasts 118 mm of travel with a 31 mm inverted fork, offering a plush ride, while the rear single shock provides 70 mm of travel, perfect for tackling urban bumps. With a seat height of just 754 mm (29.7 inches), it welcomes riders of all sizes, ensuring that everyone can hop on and feel comfortable. Available in vibrant colors like Black, Red, Yellow, and Pearl White, the Grom is not just a motorcycle; it’s a statement on two wheels. **

Pros

  • Lightweight and Agile: Easy to handle, making it perfect for city commuting and novice riders.
  • Fun Factor: The playful design and spirited performance provide an exhilarating riding experience.
  • Fuel Efficiency: With a 5.49-liter fuel capacity, riders can enjoy long rides without frequent stops at the pump.
