Installation Considerations for Optimal Performance
This Scepter 25 cartridge kit is pre-tuned to provide an excellent ride right out of the box, minimizing the need for extensive post-installation adjustments. However, it's important to note that due to the +2" cartridge length, this kit requires 2" longer fork tubes for proper installation. This ensures adequate travel and optimal geometry for your Harley Touring model, providing a significant upgrade in front-end feel and control.
