KTM Announces 2020 450 SX-F FACTORY EDITION

Chaparral Motorsports

December 20, 2019

A FORMULA FOR SUCCESS

We build and race FACTORY EDITIONS. Championship winning bikes, like this one. Thanks to its compact SOHC (single overhead camshaft) engine delivering explosive but controllable power, it is the weapon of choice for Red Bull KTM Factory Teams around the world. A lightweight chassis, slim bodywork and a powerful engine put the 450 SX-F FACTORY EDITION out front of the competition. A long list of special equipment such as a factory installed holeshot device, a floating front brake rotor and a slip-on AKRAPOVIČ muffler add to the arsenal that raises this limited edition model to a level that cannot be rivaled. The FACTORY EDITION is a formula for success.

2020 KTM 450 SX-F FACTORY EDITION Highlights

  • NEW Red Bull KTM Factory Racing graphics, Factory seat with Selle Dalla Valle logo and orange frame for a READY TO RACE look.
  • Updated WP XACT split air fork with a redesign of the internals including a new mid-valve damping system for improved control and feel, a 10 mm increase to the bypass slot on the air-leg for enhanced initial comfort and a new oil bypass in the outer damping leg tube to reduce pressure peaks.
  • Vented airbox cover included that can be changed without the use of any tools for a sharper throttle response according to rider preference or track conditions.
  • PANKL conrod with a bushing in the small end reduces friction for a faster revving engine.
  • Billet aluminum HINSON clutch cover increases durability while enhancing the factory look.  
  • Factory CNC-machined triple clamps with adjustable offset [20 - 22 mm] and perfect fork clamping.
  • AKRAPOVIÄŒ slip-on silencer that features a lightweight titanium outer shell and permanently welded attachment points and offers an improved torque curve and perfectly rideable peak power.
  • Factory D.I.D DirtStar rims with machined, anodized hubs and three-cross pattern in the front for optimal handling.
  • Floating front waved disc with disc guard, carbon fiber reinforced engine protector and mechanical holeshot device as standard.
  • Compact SOHC (single overhead camshaft) engine with cutting-edge cylinder head featuring titanium valves and super-light finger followers with a hard DLC coating.
  • High-tech, lightweight chrome-moly steel frame with optimized stiffness provides a great blend of comfort and stability.
  • Single-piece cast aluminum swingarm features a long rear axle slot for increased adjustability, offering better straight-line stability.
  • Bodywork features a slim design for optimal comfort, control and freedom of movement. 
  • Header pipe with FDH (Flow Design Header) resonator system for improved performance.
  • Handlebar map switch selects between two maps and activates traction and launch control for better traction and more efficient starts.
  • Hydraulic BREMBO clutch system offers light operation and highly controllable modulation of the clutch.
  • High-tech BREMBO brakes for unmatched braking performance.
  • KTM's "No Dirt" foot peg design keeps the peg pivot from becoming clogged, ensuring the foot peg is always in the correct position.
  • "No Dirt" shift lever prevents dirt from fouling the lever joint to ensure proper shifting in any condition.
