2019 KTM 250 SX-F

Overview Engine & Exhaust Chassis Ergonomics & Comfort Bodywork & Graphics Software & Electronics

Chassis

Every rider knows that when the feeling on the bike is good, the ride is awesome. The chassis forms an integral part of this "feeling" and has been designed to provide accurate feedback between track and rider, while also reducing the harshness of typical motocross terrain. The KTM 250 SX-F features a new lightweight, high-tech steel frame that not only provides a great feeling, but has been optimized for more accurate rider feedback. The new flex characteristics provide excellent agility and high-speed stability, contributing to an intuitive ride like no other.

Framework

Frame

…The high-tech, lightweight chrome-moly steel frame has a knack for easy handling, outlandish rideability, precise cornering and excellent stability. You can also count on high torsional rigidity and low longitudinal stiffness. This results in better absorption of the energy created from the front and rear suspension, sucking up jumps and bumps. In short: more comfort and less rider fatigue. Laterally attached, lightweight aluminum engine head stays (the connection between cylinder head and frame) contribute to more precise cornering and a reduced vibration level. The engineers were able to pull off all that, while making their frame 2.2 pounds lighter than that of the lightest competitor on the market. In addition, it is easier to maintain, easier to work on and supplies more space for the tank and other components. The bike also features an extra-light subframe made of aluminum, which tips the scales at less than 2 pounds.

Front suspension

…All full-size SX models are fitted with the super-lightweight WP AER 48 front fork. It is a 48 mm USD air-sprung fork with separate functions for each fork leg, meaning damping functions are on the right side and the air spring is on the left. The left leg features a two-chamber system with a capsuled air cartridge, helping prevent loss of air pressure. Essentially, this means that in the rare case of a leaking outer seal, the internal cartridge pressure keeps the bike in a normal position. The air spring is exceptionally easy to use and can be adjusted to any rider weight via a single air valve and the air pump that is supplied with the bike. The right fork leg integrates a damping cartridge to fit single damping leg requirements and can be adjusted to the track conditions and the rider's preferences. (compression from top, rebound from bottom, 30 clicks each). For 2019, new settings on the damping side have improved the damping characteristics, providing great front end feel and control.

Rear suspension

…The WP shock absorber has been developed with the entire frame and swingarm architecture in mind, including the linkage and the WP AER 48 front fork. It features machined and black anodized components and is a valuable, high-end product compared to roughcast reservoirs. A new, confidence inspiring setting with improved damping characteristics perfectly matches the front-end setup and its striking WP color scheme lets everyone know you have excellent taste in suspension.

Factory start

…This is how the factory riders start! The factory start is mounted directly on the fork. Before the start, the fork is dipped and fixed in the desired position to shift the center of gravity forward. This to a large extent prevents the front wheel from lifting at the start, thus providing greater traction and perhaps securing you the odd holeshot or two. The first time the fork dips, the fixing is slackened and the fork released automatically.

…DO YOU KNOW that all KTM CNC parts are manufactured from highest quality aluminium and therefore not only look good, they also withstand the toughest treatment? With the anodised aluminium components in the original factory look from the PowerParts range, you can turn your KTM into something very special. Wider contact surface than standard: +8 mm on 125/150 SX/XC-W, 450 SX-F +16 mm on 250/300 SX/EXC, 250/350 SX-F/EXC-F

Z-ring chain

…Do you know about the differences and benefits of a Z-ring or X-ring chain compared with an O-ring chain? » The Z-ring or X-ring has 4 contact points in contrast to 2 contact points with the O-ring version » This means higher flexibility and better running characteristics for the Z-ring or X-ring chain » The spring effect of the Z-ring or X-ring guarantees consistent and permanent lubrication » This means a significantly longer service life for the Z-ring or X-ring chain » The Z-ring or X-ring provides a better seal against penetration by water and dirt
