Replace and/or upgrade your swingarm bearings with these high quality replacement bearing kits. Made in Japan to the same high quality standards adhered to by the original equipment manufacturers. They will upgrade the standard bushings with low friction needle bearings. The needle bearings allow tighter clearances to minimize swingarm flex and rotate smoothly with no binding. The stainless steel shaft is stronger than OEM and helps to minimize flex. Please see the detailed description for more information.
