Overview

Introducing the 2010 KTM 125 EXC, a powerhouse in the enduro-offroad category designed for riders who crave agility and performance on demanding terrains. This model is part of KTM's prestigious Offroad Competition ECX series, which has earned a well-deserved reputation for delivering fierce competition and unbeatable durability. With a lightweight chassis and a powerful two-stroke engine, the 125 EXC stands out as an ideal option for both seasoned racers and enthusiastic amateurs looking to push their limits. At the heart of the KTM 125 EXC lies a robust single-cylinder, two-stroke engine that boasts a displacement of 124.80 ccm. With a bore and stroke of 54.0 x 54.5 mm, this engine delivers a thrilling, responsive ride that keeps the adrenaline flowing. The Keihin PWK 36 S AG carburettor ensures optimal fuel delivery, providing an exhilarating power band that is both potent and manageable, making it perfect for tight trails and sweeping dirt roads alike. The 6-speed gearbox paired with a wet double disk clutch operated hydraulically enhances the rider's control, allowing seamless gear shifts that support aggressive riding styles while maintaining smooth operation. The 2010 KTM 125 EXC is not just about raw power; it's armed with a suite of features and technology that elevate the riding experience. Its central double-cradle-type frame constructed from 25CrMo4 steel ensures a sturdy yet lightweight structure, enhancing maneuverability on the roughest terrains. The WP USD front suspension offers an impressive 300 mm of travel, while the rear WP PDS shock absorber provides 335 mm of travel—both designed to absorb bumps and maintain traction over varied surfaces. With a ground clearance of 390 mm and a seat height of 985 mm, this bike is designed for confident handling, allowing riders to navigate obstacles with ease. **

Pros

  • Agile Handling: Lightweight design combined with an advanced suspension system allows for nimble maneuverability in challenging terrains.
  • Powerful Engine: The two-stroke engine provides a responsive power delivery that enhances performance, especially in tight and technical sections.
  • Durable Construction: Built with high-quality materials and engineering, the KTM 125 EXC is designed to withstand the rigors of off-road competition.

Cons

  • Kick Start Only: The absence of an electric start may deter some riders who prefer the convenience and ease of modern starting systems.
  • Seat Height: At 985 mm, the seat height may be challenging for shorter riders, potentially compromising their confidence and comfort.
  • Limited Fuel Capacity: With a fuel capacity of only 9.50 liters (2.51 gallons), longer rides may necessitate frequent refueling stops, which can interrupt the flow of a day’s adventure.
