UMI Bearing and O-Ring Rebuild Kit for SuperJet Steering
The UMI Racing replacement bearing and o-ring rebuild kit for Yamaha SuperJet steering systems is the simple way to restore a smooth, tight feel to your controls. Over time, bearings wear, o-rings lose tension, and steering can begin to feel notchy or loose. This kit includes the correct components to refresh your UMI steering system so it feels close to new again.
Designed specifically for UMI steering used on Yamaha SuperJet 700 models, this kit focuses on wear items that see constant movement and water exposure. Regular maintenance of these parts helps prevent premature play, corrosion, and binding, all of which can make riding less precise and more tiring.
Kit Contents
- 1 ball bearing to support rotational movement of the steering system
- 1 flat roller bearing to manage axial loads smoothly under aggressive riding
- 3 o-rings that help seal out water and debris and maintain snug fitment
- 2 washers sized for proper spacing within the UMI steering assembly
Why Refresh Your UMI Steering
Even the best billet steering hardware depends on healthy bearings and seals to work correctly. As those internal parts wear, the bars can develop play or a rough feel through the turn. By replacing these service parts before they fail, you keep your SuperJet steering consistent and predictable.
For riders who log many hours in surf or rough water, rebuilding the steering on a regular schedule is just as important as pump or engine maintenance. This UMI Racing kit provides the correct pieces in one package so you are not guessing at sizes or mixing unmatched bearings. It is a small investment that can make a big difference in how your Yamaha SuperJet handles.
