Overview

Introducing the 2009 KTM 85 SX 17-14, a formidable contender in the minibike-cross category, designed specifically for the young and aspiring motocross enthusiasts. KTM has crafted this model to blend high-performance engineering with lightweight agility, making it the perfect machine for budding riders eager to conquer the dirt. Whether on the track or navigating through challenging trails, the 85 SX is engineered to deliver the thrilling experience that KTM is renowned for, allowing younger riders to build their skills with confidence. At the heart of the 2009 KTM 85 SX lies a potent single-cylinder, two-stroke engine with a displacement of 84.90 ccm (5.18 cubic inches). This powerhouse features a bore and stroke of 47.0 x 49.0 mm, delivering robust power and impressive torque. The engine is fed by a precise Keihin PWK 28 carburettor, ensuring responsive throttle control and smooth power delivery. With a 6-speed gearbox and a wet multi-disc hydraulic clutch, the KTM 85 SX offers an exhilarating ride that is both engaging and manageable for younger riders. The liquid cooling system helps maintain optimal engine temperatures, allowing for longer rides without the risk of overheating. With a lightweight frame weighing just 66 kg (145.5 pounds), the bike's agility shines, making it easy to handle and maneuver through tight turns and jumps. KTM has equipped the 85 SX with advanced suspension and braking technology to enhance the riding experience. The WP USD front forks, with a generous travel of 280 mm (11.0 inches), and the WP monoshock PDS rear suspension with 300 mm (11.8 inches) of travel work in harmony to absorb bumps and provide stability on rough terrain. The double-cradle frame, combined with the aluminum subframe, ensures both strength and lightness, making the bike responsive and easy to control. For stopping power, the 85 SX features a Brembo single disc brake system both at the front (220 mm) and rear (200 mm), providing reliable braking performance when it matters most. With a seat height of 845 mm (33.3 inches), this model is tailored for young riders, offering a comfortable and confident riding position. **

Pros

  • Lightweight and Agile: Weighing only 66 kg, the KTM 85 SX is easy to handle, ideal for young riders still developing their skills.
  • Powerful Performance: The two-stroke engine delivers excellent power and torque, making it fun for riders looking to push their limits on the track.
  • Advanced Suspension: The WP suspension system offers ample travel and stability, allowing riders to tackle jumps and rough terrain with confidence.

Cons

  • Limited Fuel Capacity: With a tank capacity of 5 liters (1.32 gallons), fuel range may be a concern during longer rides or practice sessions.
  • Kick Start Only: The kick-start mechanism might pose a challenge for younger riders who are not yet accustomed to this starting method.
  • Niche Market: As a dedicated minibike, the 85 SX may not be as versatile for casual riders or those looking for a bike for varied terrains beyond motocross.
