Overview

Introducing the 2015 KTM RC 125, a striking blend of cutting-edge design and performance, perfectly tailored for the sport motorcycle segment. Known for its bold aesthetics and vibrant color options of Black and Orange, the RC 125 captures the essence of KTM’s racing heritage. This entry-level sportbike is designed to appeal to both novice riders seeking an agile, lightweight machine and seasoned enthusiasts looking for a fun, nimble ride. With its compact frame and aggressive stance, the RC 125 is not just a motorcycle; it’s a statement on the road. At the heart of the RC 125 is a spirited 124.70 cc single-cylinder, four-stroke engine that churns out a commendable 15 horsepower. This power is complemented by a high compression ratio of 14.5:1 and a smooth 6-speed gearbox, allowing riders to maximize acceleration and tackle twisty roads with confidence. The engine’s liquid cooling system ensures optimal temperature management, making those long rides or spirited jaunts a breeze. The well-engineered chassis, constructed from a robust tubular space frame, provides extraordinary stability while the WP suspension—featuring 125 mm of front travel and 150 mm at the rear—ensures a plush yet responsive ride, making it a joy to navigate through urban streets or the racetrack. The 2015 KTM RC 125 isn't just about performance; it's equipped with technology that enhances the riding experience. The bike features a fully electronic ignition system with digital timing adjustment, ensuring quick starts and consistent performance. Safety is paramount, and the RC 125 delivers with its powerful front brakes, consisting of a 300 mm disc paired with four-piston calipers, providing impressive stopping power. The lightweight design, tipping the scales at just 135 kg, coupled with a power-to-weight ratio of 0.1111 HP/kg, ensures that every twist of the throttle translates into exhilarating acceleration. With a seat height of 820 mm, it caters to a wide range of riders, offering comfort and control. **

Pros

  • Lightweight and Agile: At just 135 kg, the RC 125 is nimble, making it an excellent choice for urban commuting and agile handling.
  • Strong Braking System: The advanced braking setup, featuring a 300 mm front disc with four-piston calipers, provides exceptional stopping power.
  • Sporty Design: Its aggressive styling and vibrant colors make it visually striking and appealing to a youth-centric audience.

Cons
