The RFX Pro chain tensioners in red anodized aluminum are axle blocks designed for off-road use. CNC machined from aerospace-grade 7075 aluminum, they provide rigidity and lightweight performance to the swingarm while offering precise adjustment thanks to tight tolerances. Their anodized finish adds color to the bike without sacrificing wear resistance, creating a polished racing look for your motocross machine.
Compatibility and Installation
Designed for the motocross world, these tensioners are suitable for KTM 85 SX models (2023-2024 listed below). Installation requires removing the rear wheel and following the alignment and chain tensioning steps. For KTM models, it is recommended to use red thread locker when reassembling the axle if necessary and to tighten the nut to the manufacturer's torque specification.
