KroozR WP AER 43mm Air Fork to Coil Spring Conversion Kit for 2018-on KTM / Husqvarna / Gas Gas 85cc Junior MX Racers
The 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 pneumatic system from your current WP Forks and replace it with a traditional preload adjustable coil spring and cartridge setup. Only one kit is required for a pair of forks
Parts included in the kit:
- Complete Cartridge Assembly
- Optional Coil Springs (to suit rider weight)
- Installation Instructions
- Decal Set
Key Features:
- Never have to set your air pressure ever again
- Super easy install - undo top cap then drain oil completely and remove base bolt. The kit slides in as a complete replacement supplied with spring installed all ready to go!
- Much more reliable fork
- No fade out or pump up in pressure over long motos - highly noticable on these 85cc machines. We are measuring 3-4psi over 20 minutes at a high level!
- A constant feel in your front end that is more consistent throughout the ride
- Spring pre-load adjustable - minimal tools are required for fitment. If you have the fork cap and basic tools to remove the standard OEM air cartridge you will have the ability to fit up our kit
- Spring fork cartridge kit is made from high grade 6061 aircraft-grade aluminium alloy with chrome moly rods and anodised for a factory finish
- User manual included

KG | Spring Rate |
---|---|
35-40 | 6.0 N/mm |

45-50 | 7.0 N/mm |
50-55 | 7.5 N/mm |

70 > | 9.0 N/mm |
General Riding and Motocross Applications.
These recommendations are a guide only as fork Springs are weight and speed dependent. For example a 44 kg A Grade Pro level rider falls into the 6.5 N/mm category but may well be better suited to a 7.0 N 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.
Also note we have had great results using one spring down for C level riders or absolute beginners on the 85cc machines. E.g. - 42kg rider running a 6.0 N/mm spring for a plusher ride.
