Front wheel bearing & seal kit for vintage Honda CT90 / Trail 90 motorcycles K1-K5.
NOTE: This wheel bearing kit only fits CT90 / Trail 90 models with the early-style brake plate (see photos). Some late-production K5 models use the later-style brake plate found on the K6 & up variants. Here is the late-style brake plate bearing kit for K6 & up.
Wheel bearings are often overlooked but are crucial for your Honda CT90 / Trail 90’s performance and safety. They are prone to damage from moisture (such as riding through puddles), which causes rust and wear over time. If your front wheel feels rough when spinning or has excessive lateral play, it's time to replace the wheel bearings.
Place the new bearings in the freezer for a few hours before installation. This will slightly shrink the bearings, making them easier to install. Use a heat gun on the hub to expand the aluminum, which helps with both removing the old bearings and installing the new ones.
To install, use a large socket or a tube just smaller than the new bearing's outer race to drive the bearings into place. Do not press on the inner race or dust covers, as this will damage the bearing during installation.
