Upgrade the original Beta Evo/Sincro frame/swingarm spindle assembly with the Jitsie Race spindle kit. Manufactured from premium materials, the kit features a CNC machined 7075-T6 aluminium spindle combined with a high-strength 303 stainless steel nut, replacing the original aluminium spindle and nut for improved durability and reliability. The original frame/swingarm spindle on the Beta Sincro is installed from the sprocket side towards the brake disc side, leaving the retaining nut exposed on the kickstart side. During use, the kickstart can rub against this nut, gradually damaging both the nut and the kickstart itself. The exposed nut can also catch on your boot, accelerating wear to the sole and stitching. On the Jitsie frame/swingarm spindle kit Race, the spindle is installed from the brake disc side, eliminating the exposed nut on the kickstart side and preventing contact with the kickstart lever. A precision-machined POM protective cap, secured with a Torx T25 screw, covers the stainless steel nut on the sprocket side to create a smooth profile that helps minimise wear on your riding boots. The result is a cleaner finish, improved durability, better protection for your boots and a smarter overall design.
