Overview

Introducing the 2017 KTM 450 SX-F, a powerful contender in the cross-motocross category that embodies the essence of racing performance and cutting-edge technology. KTM has long been recognized for its commitment to innovation and quality, and the 450 SX-F is no exception. Designed for serious racers and dedicated enthusiasts alike, this motorcycle combines a potent engine with lightweight construction, making it a formidable machine on the track or the trails. With its striking orange, white, and black aesthetics, the KTM 450 SX-F is not just a bike; it’s a statement of intent for those who seek speed and agility. At the heart of the KTM 450 SX-F lies a robust 449.30 ccm single-cylinder, four-stroke engine that delivers exhilarating power and responsiveness. The engine's bore and stroke dimensions—95.0 x 63.4 mm—work in harmony with the sophisticated Keihin fuel injection system to produce impressive torque and acceleration. Riders will appreciate the seamless power delivery, whether navigating tight corners or powering down straightaways. Matched with a 4-speed gearbox and a wet, DDS multi-disc clutch featuring Brembo hydraulics, the 450 SX-F promises a smooth and engaging riding experience, allowing riders to focus on what matters most—the thrill of the ride. Beyond its formidable engine performance, the 2017 KTM 450 SX-F is equipped with advanced suspension and braking technologies that enhance rider control and comfort. The WP-USD AER 48 front suspension offers 300 mm of travel, absorbing jumps and rough terrain with ease, while the rear WP shock absorber with linkage provides an equally impressive 300 mm of travel, ensuring stability and responsiveness. The lightweight 25CrMo4 steel central-tube frame maintains rigidity without adding unnecessary weight, resulting in a total bike weight of only 100.2 kg (220.9 pounds). Combined with a ground clearance of 370 mm and an adjustable seat height of 960 mm, this motorcycle is engineered for optimal handling and rider confidence. **

Pros

  • Powerful Engine: The single-cylinder, four-stroke engine offers excellent torque and acceleration for a thrilling ride.
  • Advanced Suspension: WP suspension provides superior handling and comfort on rough terrain.
  • Lightweight Design: Weighing only 100.2 kg, the bike is agile and easy to maneuver, enhancing performance on the track.

Cons

  • Limited Fuel Capacity: With a 7.00-liter tank, fuel range may be limited for long rides or extended track sessions.
  • Seat Height: The relatively high seat height may not be suitable for shorter riders, potentially impacting comfort and control.
  • 4-Speed Gearbox: The 4-speed transmission may limit top-end speed compared to competitors with a wider gear range, especially on long straights.
