KTM 450 SX-F Factory Edition

The KTM 450 SX-F Factory Edition at Lings KTM embodies the "READY TO RACE" mantra. These special, limited-run models bridge the gap between 'stock' and 'factory' motocross machines, offering a level of performance as close to the Pros as possible. This specific bike inherits the peerless basis of the 2025 KTM SX-F motocross racers, then elevates it with a list of KTM POWERPARTS additions.

At its core is a truly manic 4-stroke engine. This 449.9 cc, 1-cylinder SOHC unit is incredibly light, weighing only 26.8 kg, and features a 2° backward tilt for optimal mass centralisation. For 2025, the engine benefits from a new exhaust header with an improved joint for enhanced durability. An electric starter, powered by a robust 12.8V 2 Ah lithium-ion battery, ensures instant and reliable starts. Riders can access a suite of electronic rider aids, including Launch Control and a Quickshifter for seamless, clutch-less upshifts, all managed via a map select switch.

The chassis is freshly loaded with an all-new arsenal of weaponry. The central double-cradle-type 25CrMo4 steel frame features a reworked rear shock mount area and updated engine mounts with cut-outs, resulting in improved chassis flex, better cornering behavior, and a 300g weight saving. It also boasts improved anti-squat characteristics for enhanced traction on acceleration. The WP XACT AER 48mm upside-down forks and WP XACT monoshock with linkage have been re-tuned for 2025, offering improved response and easy, tool-free adjustability for both high and low-speed compression, as well as rebound.

KTM POWERPARTS additions include a lightweight Akrapovič slip-on exhaust, orange CNC Factory triple clamps for precise steering, and a Factory front brake disc guard. Braking is handled by powerful Brembo disc brakes. A Factory skid plate, orange rear sprocket, and gold chain emphasize its race-bred nature. The DID Factory wheel set with Dunlop GEOMAX MX34 tyres, featuring new carcass and rubber compounds, provides improved damping, absorption, and enhanced traction. Ergonomic bodywork with a ribbed factory seat cover and Red Bull KTM Factory Racing graphics, featuring #4 and #7 options for Chase Sexton or Aaron Plessinger, ensures ultimate rider contact and control. The new Connectivity Unit Offroad (CUO) allows more interaction and setup possibilities than ever before via the KTMConnect App. The KTM 450 SX-F Factory Edition has been crafted by racers for the ultimate racecraft – try to catch it.
