2027 KTM 450 EXC-F Six Days Front ¾ view

01.Before the trail

Tool-free clickers, a fail-proof filter and a tank you can see into — the enduro that is ready before you are.

4 features

Thumb, not toolbox

Switchgear

New across the 2027 Enduro range: a slimmer start/stop switch on the right, and on the left the optional Map Select switch. Map 1 is linear and predictable for slick roots and mud; Map 2 is sharper when the grip is there. Chosen with a thumb, on the move.

Set it on the stand

Tool-free adjustability

PDS at the rear with hand-adjustable high- and low-speed compression; fork clickers on the shoe and the top cap, also by hand. A change takes the time it takes to twist them — between special tests, not between weekends.

Breathe, don't drink

Air filter box

Inlet ducts placed for maximum airflow and minimum water; an enduro-specific splash guard under the airbox stops the rear wheel feeding it mud. The Twin Air filter sits on a fail-proof mount — in and out without tools, at the side of the trail.

Built like a tank

Transparent fuel tank

8.5 litres of XPE polythene you can read at a glance, raced from the GNCC to the hardest FIM hard enduros. A one-piece pump and filter unit manages the supply, the filter is reachable for a quick service, and a protection cap keeps dirt and sticks off the fuel connector.

8.5 lcapacity

02.Torque, everywhere

29 kg of race-developed four-stroke with torque across the whole rev range — the 450 that wins championships.

7 features

From the track to the crate

450 cc four-stroke

Advanced engineering developed on the race track and handed over complete: 29 kg, strong and controllable, with torque across the rev range and the manners to use it for a full day. Keihin 42 mm throttle body, six speeds, DDS clutch with Brembo hydraulics.

449.9cm³
29 kgengine
6-speed

Tucked in, matt black

Exhaust

A two-piece header routed as close to the engine as it will go — mass where the chassis wants it and the pipe out of reach of rocks. A short aluminium silencer in matt black finishes it, at the lowest weight the performance allows.

Fan fitted

Cooling

A radiator fan is standard across the EXC and EXC-F range. First-gear climbs and the queue at a bottleneck no longer cook the engine.

Clutch stays untouched

Quickshifter

Optional: a sensor on the shift drum reads the load on the lever and the ECU cuts the ignition for a fraction of a second — full-throttle upshifts from 2nd to 6th without the clutch. Switchable off from the map switch.

Grip, managed

Traction control

Optional: the EMS watches throttle position against how fast the revs climb; when the rear spins up faster than the terrain allows, it trims the power until the tyre bites again. Switch it off for full control.

Lift the seat, read the lights

Offroad Control Unit

The OCU replaces every fuse and relay. Outputs are switched by the ECU and the regulator; an over-current shuts down the one circuit affected, and a red or green LED tells you which. Diagnosing an electrical fault on the trail means lifting the seat — not carrying spare fuses.

Press, go

Electric start

A 2 Ah lithium-ion battery and a proven starter: reliable starts, time after time. The harness puts most of the electrics under the seat, where you can reach them.

2 AhLi-ion

03.The chassis

A frame tuned for feedback, PDS at the rear and a closed-cartridge fork — the enduro chassis that has been winning for decades.

5 features

Flex where it helps

Frame

Black powder-coated 25CrMo4 steel, engineered for longitudinal rigidity: feedback, energy absorption and stability at speed. Rotating masses repositioned, a forged steering-head connection, slim footrest mounts that don't hook — and a forged one-piece side stand for when the ride is over.

Bends, doesn't break

Subframe

Two-part polyamide and reinforced aluminium with its rigidity engineered by simulation. It carries the electronics without extra brackets or holders, and in a crash it flexes rather than snaps.

Closed cartridge, open hands

WP XACT closed-cartridge fork

48 mm with optimised oil flow for fast, consistent damping; protection rings keep dirt out of the seals. Compression and rebound adjusted by hand, no tools.

Ø 48 mm
300 mmtravel

No linkage to break

WP XPLOR PDS shock

The PDS concept: no linkage, better anti-squat, more ground clearance and the least maintenance of any race rear end. Hand-adjustable high- and low-speed compression, rebound and preload.

310 mmtravel

Grip for all conditions

Wheels & tyres

High-strength GIANT alloy rims on CNC-machined hubs with aluminium nipples, wrapped in Maxxis MaxxEnduro rubber: traction in everything from wet roots to dry hardpack.

04.Into the night

An LED that lights the trail, a front end that stays calm at speed, and a body built for standing up.

3 features

Serious illumination

LED headlight

An LED unit in a light mask that also shields the triple clamp from roost. No rubber straps, so it stays where it was fitted. Riding in the dark stops being a guess.

Rock-solid at speed

Stability

A repositioned, forged steering-head connection and CNC-milled aluminium triple clamps: tuned stem stiffness, perfectly aligned fork tubes, precise clamp geometry. Smooth fork action in the tight stuff and no headshake in the flat-out tests.

Stand up, lock in

Ergonomics

A rider triangle built for standing: more knee contact, grip surfaces all round, a flat seat with a high-grip cover, and plastics shaped to throw mud off rather than carry it. The polyamide subframe adds feel at the rear.

01.Six Days spec

The ISDE edition: branded parts, protection fitted, and the same engine that wins the class.

4 features

Branded where you touch it

6DAYS components

Exhaust, cockpit, wheels and contact points carry 6DAYS-specific branding — factory-inspired finishing that marks the edition and lifts the perceived quality.

Strong, controllable

4-stroke power

Strong, controllable power with impressive torque across the rev range. The compact, light engine improves mass centralisation — stability, precise handling and confidence in demanding enduro conditions.

449.9cm³
6-speed

Stealth sprocket, compact pipe

Race-ready drivetrain

Durability and efficient power transfer under extreme conditions, with a Supersprox stealth rear sprocket for wear resistance and a compact exhaust in the 6DAYS finish.

Protection fitted

Built for extreme conditions

Radiator fan, a robust skid plate for impacts and a frame protection set for durability and grip — on the bike when it leaves the factory, not on a parts invoice afterwards.

02.Chassis for the tests

Brembo with a semi-floating front disc, WP front and rear, orange frame and orange clamps.

5 features

Semi-floating front

Brembo brakes

Brembo components with a semi-floating front disc for performance under load, a solid rear disc for durability and a rear brake safety wire for the extreme terrain.

Closed cartridge, open hands

WP XACT closed-cartridge fork

48 mm, fast and consistent damping, precise control. Compression and rebound without tools, so the settings follow the terrain.

Ø 48 mm
300 mmtravel

Progressive, no linkage

WP XPLOR PDS shock

Progressive damping, ground clearance and low maintenance — the proven rear end for extreme enduro.

310 mmtravel

Orange, on purpose

Race-optimised frame

Longitudinal rigidity for stability, feedback and confidence at speed — in the orange that marks the Six Days edition.

Orange clamps, axle puller

CNC triple clamps

Orange-anodised CNC-machined triple clamps for stiffness and alignment, and a front axle puller for quick wheel service in race conditions.

03.Brains under the seat

No fuses to carry, two maps on the bar — electronics made for six days without a support truck.

3 features

Lift the seat, read the lights

Offroad Control Unit

The OCU replaces fuses and relays with one integrated unit under the seat. It manages every output, isolates a fault on its own and shows the status per circuit on an LED — no spare fuses to carry.

Two maps, one thumb

Map-select & engine management

A handlebar map-select switch to adapt power delivery to the terrain, so the right map is one thumb away when it matters.

Grip and gears, managed

Traction control & quickshifter

Traction control trims the power when the rear spins up faster than the ground allows; the quickshifter gives clutchless full-throttle upshifts from 2nd to 6th. Momentum kept, rider fatigue not.

04.ISDE identity

Graphics from KTM's Six Days history, 6DAYS wheels and Metzeler rubber, and a seat for long days.

3 features

Heritage on the plastics

6DAYS identity

Exclusive graphics inspired by KTM's ISDE heritage, a colour scheme of its own and premium finishes — clearly a Six Days, clearly race-focused.

Grip for the tests

6DAYS traction package

High-strength 6DAYS-branded GIANT alloy wheels and Metzeler 6 Days Extreme tyres: traction, durability and control in extreme conditions.

Six days in the saddle

6DAYS seat

A dedicated seat with a high-grip surface — stability and control over long, demanding days.
