The big news when it comes to KTM’s 2017 lineup of small-bore SX motocrossers is that some of them get air forks! Returning models include the 50 SX, 50 SX Mini, 65 SX and 85 SX.
For 2017, the KTM 50 SX and 65 SX are fitted with fully adjustable air sprung forks—WP Suspension’s AER 35 air forks to be exact. These upside down forks feature 35mm-diameter tubes, offer 8.07 inches of wheel travel and are 1.7 pounds lighter than the previous spring forks. The AER forks are unique in that they house air (which acts like a spring) in one leg and all of the damping components in the other leg.
The 50 SX’s rear shock settings have been tweaked to coincide with the new fork, and it also gets a new exhaust pipe and graphics, as do all of the bikes. The 50 SX weighs 90 pounds (without fuel) and the 65 SX 115.1 pounds (without fuel).
