Overview

Introducing the 2006 KTM 85 SX, a fierce contender in the world of minibike-cross that embodies the spirit of competition and youthful exuberance. Designed for budding riders who are eager to carve their path in motocross, the 85 SX stands out with its aggressive styling and lightweight construction. KTM, renowned for its commitment to performance and innovation, has produced this model to cater specifically to the needs of younger riders, ensuring that they experience the thrill and excitement of competitive racing right from the start. At the heart of the KTM 85 SX lies a robust single-cylinder, two-stroke engine with a displacement of 84.90 cc. This powerhouse is designed to deliver an exhilarating riding experience, with an impressive bore and stroke of 47.0 x 49.0 mm that promotes quick throttle response and a spirited delivery of power. The Keihin PWK 28 carburettor optimizes fuel delivery for smooth acceleration, while the liquid cooling system keeps the engine performing at peak efficiency during intense rides. Riders will appreciate the hydraulic wet multi-disc clutch, which provides smooth engagement and control—vital for mastering those tight turns and jumps on the track. The chassis of the 2006 KTM 85 SX is a marvel of engineering, constructed from durable chromium molybdenum to ensure rigidity without compromising weight. Weighing in at just 68 kg (149.9 pounds), this bike is incredibly nimble, making it easy to maneuver in various terrains. The WP USD 43 mm front suspension and WP monoshock PDS rear suspension work in tandem to absorb shocks and maintain stability, allowing riders to tackle obstacles with confidence. Safety is also paramount, with significant stopping power provided by single disc brakes measuring 220 mm in the front and 200 mm in the rear, ensuring that young riders can brake effectively when it matters most. **

Pros

  • Lightweight Design: At only 68 kg, the KTM 85 SX is easy to handle, making it perfect for younger and less experienced riders.
  • Powerful Engine: The two-stroke engine delivers an exciting power band, providing ample acceleration and performance for competitive racing.
  • Advanced Suspension: The high-quality WP suspension setup offers excellent handling and stability, enhancing rider confidence during jumps and turns.

Cons

  • Limited Fuel Capacity: With a fuel tank size of just 5.00 liters, riders may find themselves needing to refuel more frequently during extended sessions.
  • Kick Start Only: The absence of an electric starter means that riders must rely on kick-starting, which can be challenging for those new to riding.
  • Height Considerations: With a seat height of 750 mm (29.5 inches), shorter riders may find it difficult to reach the ground comfortably, potentially affecting their confidence in maneuverability.
