KTM 350 EXC-F / XCF-W & Six Days Service Manual (2014)

KTM launched the 350 EXC-F as part of a new-generation enduro range for model year 2012, bringing the company’s successful 350 four-stroke concept from motocross into enduro competition. KTM’s own 2014 off-road media material described the 350 EXC-F as the flagship of the new EXC generation introduced two years earlier. The idea was to create an enduro machine that combined much of a 250’s agility with power closer to a 450, giving riders a middleweight option that was easier to manage in technical terrain without giving away too much performance on faster stages.

For 2014, the 350 EXC-F retained that core formula while KTM revised the broader EXC range with lighter four-stroke frames, updated bodywork, a new headlight and detail changes to improve ergonomics. The 349.7 cm³ engine uses an 88 × 57.5 mm bore and stroke, 12.3:1 compression, DOHC four-valve cylinder head, electronic fuel injection and a six-speed gearbox. Electric and kick starting were both retained. The road-homologated EXC-F variants also carried lighting, speedometer and licensing equipment, with gearing and fuel capacity varying by market.

The 350 XCF-W applied the same basic engine concept to an off-road competition role for the North American market. A 2014 road test by Ultimate Motorcycling described the model as a versatile cross-country machine that combined a wide powerband with a wide-ratio transmission, EFI and KTM’s PDS rear suspension. The factory manual shows the XCF-W using 13:52 final gearing, an 8.5-litre fuel tank and the standard WP 4860 MXMA PA fork, while the EXC-F EU/AUS and Six Days models use different final-drive ratios and, in some cases, a 9-litre tank. This made the family a flexible 350cc four-stroke enduro platform rather than a single identical specification sold worldwide.

The Six Days versions added equipment inspired by KTM’s long involvement in the International Six Days Enduro. In the 2014 manual, the key technical distinction is the WP 4860 4CS fork fitted to all Six Days models in place of the standard MXMA PA fork. The manual also provides dedicated wiring sections for both EXC-F Six Days and XCF-W Six Days variants. KTM continued to use the Six Days name as a higher-spec enduro package tied to the ISDE tradition, and the company’s official ISDE material still presents the 350 EXC-F Six Days as a dedicated competition-focused derivative.

The 350 platform continued to evolve after 2014, with KTM introducing later generations featuring revised engines, frames, suspension and bodywork. A major break came with the 2020 enduro generation, when KTM announced substantially updated EXC-F and XCF-W models with new chassis, WP XPLOR suspension, revised engines, cooling and exhaust systems. This listing is limited to the 2014 factory Repair Manual, which covers 350 EXC-F EU, 350 EXC-F Six Days EU, 350 EXC-F AUS, 350 EXC-F USA, 350 XCF-W USA and 350 XCF-W Six Days USA. Related factory publications are grouped in the KTM 350 EXC-F manual catalog.
