Major overhaul for KTM EXC enduro range

The KTM EXC range has been completely redesigned for 2024, with the Austrian firm claiming that the enduro machines feature 95 per cent new components.

Following the example set by the 2023 SX motocross range, the new EXC range benefits from an all-new frame, enhanced suspension, refined body work, and a host of new technology.

Notably, the two-stroke models feature the same throttle body fuel injection system found in the motocross versions, while the four-stroke models add optional traction control and a quickshifter – a first for enduro motorcycles.

Both the two-stroke and four-stroke ranges now utilise a hydro-formed, laser-cut, and robot welded frame, that is designed for unmatched rider feedback, energy absorption, and straight-line stability.

Also new is the 48mm WP XACT closed-cartridge spring fork and new WP XPLOR PDS rear shock. The fork features a new mid-valve piston concept that optimises oil flow within the cartridge, while the PDS system has been updated and optimised to work with the new frame.

The lightweight 2-piece polyamide/aluminium subframe is also new, while the new bodywork has been developed with input from the Red Bull KTM factory team. All of the electronic components are housed within the subframe for easy access.

Speaking of electronics, the independent ECU (or OCU as KTM calls it) is situated under the seat, which replaces the use of electronic fuses and relays. According to KTM, in the event of any electrical component failure, the outputs are deactivated individually, with the error status of each unit indicated by a red or green LED light. This is designed for easy troubleshooting on the trail.

The four-stroke range, which includes the 250 EXC-F, 350 EXC-F, 450 EXC-F, and 500 EXC-F models, benefits from an improved centre of gravity that is achieved by tilting the engine 2 degrees backwards and repositioning the front sprocket 3mm lower.

And as we’ve already mentioned, the four-stroke range benefits from traction control as an optional extra and an industry-first quick shift function which can be toggled on or off via an optional and redesigned map switch.

The two-stroke range includes the 150 EXC, 250 EXC, and 300 EXC, all of which featured a new electronic throttle body injection system. The reed valve case has also been updated, with new plastic flaps on the outside for improved sealing of the intake tract. This is designed to avoide fuel excess in extreme up or downhill sections that could lead to the fuel running rich. The two-strokes also allow for two different engine maps and an optional map switch.

The 2024 KTM EXC and EXC-F range is expected to hit Australian and New Zealand dealerships from September 2023 onwards. Pricing is yet to be announced, but a price hike from the previous model year is likely.
