Upgrade your motorcycle's fork performance with the ALL BALLS Fork Seal Kit Part #55-144, designed for select BMW K series models and the Moto Guzzi 850 Lemans. These high-quality seals feature a patented three-lip fork seal design that ensures even pressure distribution, which helps reduce operating temperature, minimize wear, and lower friction for smoother suspension action. The custom elastomer construction has been rigorously tested to outlast OEM seals, providing a significant extension of service life—typically three to five times longer—thus reducing maintenance frequency and costs.
The seals' innovative design results in substantially lower stiction, measuring from one-third to one-half less than OEM parts, leading to more responsive and smoother fork operation. This improvement enhances rider comfort and handling stability, especially over rough terrain or during aggressive riding. Sold in pairs, these seals are a direct replacement for your existing fork seals, offering an easy upgrade to restore or improve your bike's suspension performance.
Compatible with a range of BMW K series models from 1989 to 1993 and the 1983 Moto Guzzi 850 Lemans, this kit is ideal for riders seeking durability and optimal fork function. Proper installation ensures your motorcycle maintains its handling precision, reduces fork oil leaks, and prolongs the lifespan of your suspension components. Investing in the ALL BALLS Fork Seal Kit means choosing a reliable, long-lasting solution backed by advanced sealing technology to keep your motorcycle performing at its best.
