KTM/Husqvarna ‘WP AER 43’ Air to spring conversion kit (ATS) is aimed to suit all the current AER43 Equipped Husqvarna and KTM 85 cc racers.
Fits All 2018-2020 KTM 85SX and Husqvarna TC85cc racers
Recommended spring rate for rider weight ( without gear )
Our WP43 ATS Air to spring conversion kit is a complete replacement cartridge assembly for your current WP AER43 AIR Fork setup. It is designed to completely remove all the Air system from your current WP43 Fork and replace it with a preload adjustable spring and cartridge setup. High Quality Springs are available to suit varying rider weights.
These recommendations are a guide only as fork Springs are weight and speed dependant. For example a 44 kg A GRADE ‘Pro level’ rider falls into the .65kg/mm category but may well be better suited to a 0.70kg spring due to the much higher corner entry speed and the ability to hit large bumps at high speeds. Please note this guide is for rider weight ‘without’ gear.
Please note we have had great results using one spring down for C level riders or absolute beginners on the 85cc machines. Eg. 42kg rider running a 0.60kg/mm spring for a plusher ride.
