Upgrade your motorcycle's suspension with the ALL BALLS Fork Seal Kit, part number 55-133, designed specifically for select Yamaha YZ and DT models from the 1970s. Crafted with patented fork seal technology, these seals feature a balanced three-lip design that evenly distributes pressure across the seal surface, which helps reduce operating temperature, minimize wear, and lower friction for smoother fork action. This innovative design ensures enhanced performance and durability, making it a reliable choice for restoring your bike's handling characteristics.
The custom elastomer seals have been rigorously tested and proven to outlast original OEM seals by three to five times, providing extended service life and reducing the need for frequent replacements. This longevity is especially advantageous for riders who demand consistent performance over many riding seasons. Additionally, the seals' reduced stiction—measuring between one-third and one-half less than OEM counterparts—means less resistance during fork movement, resulting in improved ride comfort and responsiveness.
Sold in pairs, this kit is an ideal upgrade for vintage Yamaha models including the YZ100, YZ125, and various DT series bikes from 1975 to 1978. Easy to install, the ALL BALLS Fork Seal Kit offers a cost-effective solution for restoring fork integrity and performance. Whether you're performing routine maintenance or a complete overhaul, these seals will help ensure your motorcycle delivers optimal handling and stability on the trail or track.
