Overview

Introducing the 2008 KTM 125 SX: A Lightweight Champion for Off-Road Enthusiasts The 2008 KTM 125 SX stands as a beacon for aspiring motocross riders and seasoned enthusiasts, seamlessly blending performance with agility in the competitive world of enduro-offroad motorcycles. KTM has made a name for itself with its commitment to engineering excellence, and the 125 SX is no exception. This model is particularly designed for young riders and those new to the sport, offering a lightweight chassis and responsive handling that instills confidence on the track and trails. With a weight of just 90.8 kg (200.2 pounds), this nimble machine is ready to conquer any terrain, making it a favorite among racers and recreational riders alike. At the heart of the 2008 KTM 125 SX lies a spirited single-cylinder, two-stroke engine with a displacement of 124.80 ccm. This powerplant is finely tuned to deliver thrilling acceleration and impressive torque, ensuring that riders can tackle steep inclines and challenging obstacles with ease. The engine's bore and stroke dimensions (54.0 x 54.5 mm) contribute to its high-revving nature, while the Keihin PWK 39 carburettor ensures optimal fuel delivery for peak performance. Coupled with a 6-speed gearbox and a hydraulically operated wet multi-disc clutch, the 125 SX provides smooth, precise shifts that keep riders in control whether they’re navigating tight corners or blasting down straights. The liquid cooling system helps maintain optimal operating temperatures, ensuring consistent performance even during the most demanding rides. The 2008 KTM 125 SX is not just about raw power; it also boasts advanced features that enhance both handling and rider comfort. The central double-cradle frame made from 25CrMo4 steel offers exceptional rigidity while remaining lightweight, allowing for precise maneuverability on diverse terrains. Up front, the WP USD forks with a generous 300 mm (11.8 inches) of travel absorb bumps and jumps effortlessly, while the rear suspension, featuring a WP monoshock PDS with 335 mm (13.2 inches) of travel, provides stability and traction over rough ground. The braking system is equally impressive, equipped with a 260 mm front disc and a 220 mm rear disc that deliver reliable stopping power, ensuring rider safety without sacrificing performance. With a seat height of 960 mm (37.8 inches), the bike is designed to accommodate various rider sizes, while the kick starter provides reliable ignition in the heat of competition. **
