Overview

Introducing the 2007 KTM 450 EXC Racing, a powerhouse in the world of enduro motorcycles. Positioned as a premium racing machine, the 450 EXC caters to serious off-road enthusiasts who demand both performance and agility. With its rugged design and competition-ready attributes, this motorcycle is engineered for riders who thrive on challenging terrain, whether tackling rocky trails or navigating muddy tracks. KTM has built a reputation for creating machines that exude passion for adventure, and the 450 EXC Racing is no exception, boasting a blend of cutting-edge technology and race-proven engineering. At the heart of the 450 EXC is a potent single-cylinder, four-stroke engine with a displacement of 447.92 ccm. This engine is calibrated for optimal performance, featuring a compression ratio of 11.0:1, which translates to impressive acceleration and torque. The Keihin MX FCR 39 carburettor fuels this beast, ensuring a responsive throttle and rapid power delivery. Riders will appreciate the smooth shifting provided by the 6-speed gearbox, complemented by a hydraulically-operated wet multi-disc clutch that offers precise control during aggressive maneuvers. With a lightweight frame weighing just 113.5 kg (250.2 pounds), the 450 EXC delivers exceptional handling and agility, making it a joy to ride in even the most challenging off-road conditions. KTM has not skimped on technology and features, equipping the 450 EXC with a central double-cradle frame constructed from 25CrMo4 steel, providing both strength and flexibility. The WP suspension system, featuring an upside-down front fork and a rear monoshock PDS, delivers 115 mm (4.5 inches) of travel in the front and an impressive 185 mm (7.3 inches) at the rear, ensuring that riders can tackle rough terrains with confidence. The bike’s ground clearance of 380 mm (15.0 inches) keeps you above obstacles, while the kick starter provides reliability in remote locations. The combination of advanced braking systems with single discs both front and rear guarantees stopping power when it’s needed most, reinforcing the 450 EXC's reputation as a top-tier enduro motorcycle. **

Pros

  • Exceptional Power-to-Weight Ratio: The lightweight build combined with a powerful engine offers exhilarating performance and agility on tough trails.
  • Advanced Suspension: The premium WP suspension provides superior handling and comfort, absorbing bumps and ensuring stability on various terrains.
  • Race-Ready Features: Built for competitive racing, it includes a responsive throttle, robust brakes, and a durable frame, making it an ideal choice for serious off-road riders.

Cons

  • Kick Start Only: The absence of an electric start may deter some riders, especially in challenging situations where quick starts are essential.
  • Seat Height: At 925 mm (36.4 inches), the seat height may be too tall for shorter riders, making it less accessible for a wider audience.
  • Fuel Capacity: With an 8-liter (2.11-gallon) fuel tank, the range may be limited for long-distance rides, necessitating frequent refueling during extended outings.
