Overview

Introducing the 2018 KTM RC 125, a dynamic entry into the world of sport motorcycles, designed specifically to captivate the hearts of both novice riders and seasoned enthusiasts. With its sleek design and aggressive stance, the RC 125 stands out in the competitive lightweight sport segment. KTM has expertly crafted this model to deliver a thrilling riding experience while remaining accessible for those stepping into the sportbike realm. Whether you're navigating city streets or carving through winding back roads, the RC 125 promises an exhilarating ride that embodies the spirit of racing. At the core of the RC 125 is a spirited 124.7cc single-cylinder, four-stroke engine, which produces a peppy 15 horsepower and 12 Nm of torque. This powertrain, paired with a precise 6-speed gearbox, offers a delightful balance of performance and efficiency—perfect for both urban commuting and spirited weekend rides. The liquid-cooled engine, featuring a high compression ratio of 14.5:1 and a sophisticated Bosch EMS ignition system, ensures smooth power delivery at all revs, giving riders the confidence to push their limits. The lightweight construction, with a total weight of only 135 kg (297.6 lbs), enhances agility, allowing riders to flick the RC 125 effortlessly through corners, making every twist of the throttle feel exhilarating. The RC 125 is packed with an array of features that elevate its appeal. The steel trellis frame not only provides structural integrity but also contributes to the bike's agile handling characteristics. The WP suspension components—an upside-down front fork and a monoshock rear—offer exceptional feedback and stability, ensuring a comfortable ride over varied terrains. Safety is paramount, and the RC 125 is equipped with ABS on both the front and rear brakes, providing reassurance when it counts. With a sporty riding position complemented by a seat height of 820 mm, this machine is designed for both comfort and control. The visually striking color options of white, grey, and orange further accentuate its racing pedigree, making it a head-turner on the streets. **

Pros

  • Agile Handling: The lightweight frame and responsive suspension make the RC 125 exceptionally nimble, perfect for navigating urban environments or twisting roads.
  • Sporty Design: The aggressive styling and color schemes embody the essence of racing, appealing to younger riders and those young at heart.
  • Technology-Driven: Equipped with advanced features such as ABS brakes and a modern fuel injection system, the RC 125 blends performance with safety and efficiency.

Cons

  • Limited Power for Highway Use: While the engine performs well in urban settings, the 15 HP may feel underpowered for sustained highway speeds, especially for taller riders.
  • Comfort for Long Rides: The sporty riding position may become uncomfortable on longer journeys, making it less ideal for extended touring.
  • Small Fuel Tank: With a fuel capacity of just 10 liters (2.64 gallons), riders may find themselves refueling more often during longer rides or commutes.
