Overview

Introducing the 2012 KTM 505 SX, a powerful ATV that embodies the spirit of off-road adventure and performance. Designed for both competitive riders and weekend warriors, the 505 SX stands out in a crowded market with its impressive specs and race-ready pedigree. KTM’s commitment to quality and innovation shines through in every detail of this machine, making it a popular choice for those who demand both agility and power from their ride. Whether you’re navigating rugged trails or tearing up the track, the 505 SX is engineered to deliver an exhilarating experience. At the heart of the 2012 KTM 505 SX lies a robust 477.50 ccm single-cylinder, four-stroke engine, designed to provide an impressive blend of torque and horsepower. With a compression ratio of 11.0:1 and a bore and stroke of 100.0 x 60.8 mm, this engine is built for performance, allowing riders to tackle steep inclines and rough terrains with confidence. The Keihin FCR MX 39 carburetor ensures optimal fuel delivery, while the fully electronic ignition system guarantees precise timing adjustments for peak performance. With a 5-speed gearbox and a wet multi-disc, hydraulically operated clutch, transitioning through gears feels seamless, providing the responsiveness that off-road enthusiasts crave. Coupled with a liquid cooling system, this engine remains efficient and reliable, even under the most demanding conditions. The 505 SX is not just about raw power; it incorporates advanced technology and features that enhance the riding experience. Its double-cradle frame, made from durable chrome-molybdenum steel tubing, provides the strength and stability required for aggressive riding while maintaining a lightweight profile. The independent front suspension with a double wishbone design offers 244 mm of travel, ensuring that rough terrains are absorbed effectively, while the rigid rear axle, with 258 mm of travel, contributes to a stable ride. Stopping power is equally impressive, with double disc brakes at the front and a single disc at the rear, providing riders with confidence-inspiring control. With a ground clearance of 265 mm and a seat height adjustable to 795 mm, the 505 SX accommodates a variety of rider preferences, making it an accessible choice for many. **

Pros

  • Impressive Performance: The powerful engine and responsive gearbox deliver thrilling acceleration and top-end speed, making it perfect for both competitive racing and trail riding.
  • Advanced Suspension: With excellent travel in both front and rear suspension, this ATV excels in absorbing bumps and rough terrain, ensuring a smooth ride.
  • Durable Frame: The robust construction of the frame provides stability and reliability, instilling confidence even in the most demanding off-road conditions.

Cons

  • Weight: At 165 kg (363.8 pounds), it may feel heavy for some riders, particularly in technical sections where agility is key.
  • Fuel Capacity: With a 13.40-litre (3.54 gallons) tank, fuel range may be limiting for longer rides, requiring more frequent stops for refueling.
  • Seat Height: While adjustable, the seat height of 795 mm (31.3 inches) may be a challenge for shorter riders, potentially affecting overall comfort and control.
