2018 KTM 450 XC-F
The 2018 450 XC-F is the ultimate READY TO RACE cross-country race machine. Building on the updated for 2017 450 SX-F, KTM’s engineers have checked all of the boxes to make the 450 XC-F an off-road winner. Updated damping settings on the WP AER 48 fork and rear shock, new clutch plates and revised radiator guards further enhance the 450 XC-F. XC specific equipment such as the translucent polyethylene 2.25 gallon fuel tank, hand guards and an 18" rear wheel ensure that the 450 XC-F is unstoppable in off-road closedcourse competition.
- UPDATED WP AER 48 front fork with a sophisticated air spring design and separate damping for easy adjustment to any track condition, rider weight or skill level. A new setting improves damping.
- UPDATED rear suspension damping settings are perfectly matched to the WP AER 48 front fork.
- NEW radiator guards provide better airflow in muddy conditions.
- NEW C4 bearing fitted to the transmission shaft for a bigger overlap in the cases for improved reliability at high operating temperatures.
- NEW clutch plates from nitrated steel for reduced wear on the steel clutch basket.
- NEW stronger lithium-ion battery provides more reliable starting while still being extremely lightweight.
- NEW MIM (Metal Inject Molded) shift star provides a stronger surface for improved reliability.
- Handlebar map switch that also activates traction control and launch control for enhanced traction for the start, middle and end of the race
- Handlebar clamps feature a separated lower clamp and bridge-type upper clamp for more torsional stiffness.
- A lightweight chromoly steel frame provides high torsional rigidity with less longitudinal stiffness resulting in excellent handling and energy absorption
- KTM’s “No Dirt” footpeg design keeps the pegs pivot from becoming clogged, ensuring the footpeg is always in the correct position.
- Super lightweight Galfer Wave rotors, CNC machined hubs, Giant rims and Dunlop GEOMAX AT81 tires.
- Airbox and filter design provides maximum performance with fast “no tools” air filter changes.
- “No Dirt” shift lever prevents dirt from fouling the lever joint to ensure proper shifting in any condition.
- Off-road specific additions such as hand guards, a side stand and a 18” rear wheel ensures the 2018 KTM 450 XC-F is READY TO RACE
