Overview

Introducing the 2007 KTM 125 EXC, a fierce contender in the enduro-offroad category that captures the essence of lightweight agility and raw power. Designed for both novice and experienced riders, this motorcycle earns its stripes on challenging trails and rugged terrains. With its nimble frame and robust engineering, the 125 EXC stands as a testament to KTM's commitment to performance and durability, making it a popular choice among off-road enthusiasts looking for an exhilarating ride without the bulk. At the heart of the 125 EXC lies a potent 124.80 ccm single-cylinder, two-stroke engine that revs with an impressive 12.5:1 compression ratio. This spirited powerplant is fed by a Keihin PWK 36 S AG carburettor, ensuring precise fuel delivery for that immediate throttle response the brand is known for. With a smooth 6-speed gearbox and a wet multi-disc hydraulic clutch, riders can seamlessly navigate through gears while tackling steep climbs or rocky descents. The liquid cooling system keeps the engine performing optimally, allowing for extended rides without overheating, and the lightweight chassis at 98.6 kg (217.4 pounds) enhances maneuverability, making it feel like an extension of the rider’s body. The 125 EXC is packed with features that enhance both performance and comfort. Its central double-cradle frame made from 25CrMo4 steel provides impressive strength and stability, while the WP USD front suspension and WP monoshock PDS rear suspension offer 115 mm and 185 mm of travel, respectively, allowing it to soak up bumps and obstacles with ease. With a ground clearance of 390 mm (15.4 inches) and a seat height of 925 mm (36.4 inches), this bike is designed to handle the ruggedness of off-road environments while still being accessible for a variety of rider heights. The single disc brakes front and rear ensure reliable stopping power, crucial for navigating tricky trails. **

Pros

  • Lightweight Design: At just 98.6 kg, the 125 EXC is highly maneuverable, making it perfect for technical trails and tight corners.
  • Powerful Engine: The 124.80 ccm two-stroke engine delivers quick acceleration and a thrilling ride, ideal for off-road enthusiasts.
  • Advanced Suspension: The WP suspension system provides exceptional travel and responsiveness, allowing for superior handling over rough terrains.

Cons

  • Kick Start Only: The absence of an electric starter can be a drawback for some riders, especially in tough conditions.
  • Limited Fuel Capacity: With an 8.50-litre fuel tank, longer rides may require more frequent refueling stops.
  • Height and Clearance: The seat height may be challenging for shorter riders, and the bike’s configuration may not suit everyone’s personal preferences.
