Say goodbye to the stock swing arm and hello to improved handling and performance with the Judd Racing Evolution Swing Arm, made specifically for the 2016-2019 KTM 50 SX and 2017-2019 Husqvarna TC 50.

Built for Riders, by Riders:

Crafted in the UK:This premium swing arm is designed and manufactured with precision by Judd Racing, known for their dedication to quality and performance.

Enhanced Handling:Experience a noticeable improvement in agility and control compared to the original swing arm.


Big Wheel Ready: Perfect for converting your mini bike to big wheels for added stability and ground clearance.


Precise Chain Alignment: The innovative chain guide bracket allows for fine-tuning the chain alignment for optimal performance, whether you're using standard or larger sprockets.


Important Notes:

Compatibility: This swing arm fits 2016-2019 KTM 50 SX models (not Mini) and 2017-2019 Husqvarna TC 50s. For earlier models (2009-2015 KTM 50 SX), a chain guide upgrade is required.


2020 and Later Models: If you have a 2020 or later KTM 50 SX/TC, a separate conversion kit is available to adapt the Evolution swing arm.


Bearings Included: This swing arm comes pre-installed with needle roller bearings for smooth operation.


11t Front Sprocket Recommended: To prevent excessive wear and tear, Judd Racing recommends using an 11t front sprocket with this swing arm.
