The UMI Racing billet turn plate is a front‑end steering upgrade built for riders who demand precision and durability. Designed for Yamaha SuperJet models (1990–2020) and compatible with Kawasaki 800SXR when paired with a UMI handlepole using the UMI Racing Steering Mounting System, this plate delivers the rigidity and control that OEM stamped plates simply can’t provide.

Machined from solid billet aluminum and finished in black anodize, the UMI turn plate eliminates flex and steering deflection, keeping your bars and linkage aligned under heavy load. The result is cleaner input at the pump, more predictable handling, and increased confidence whether you’re carving surf, freeriding, or pushing through tight closed‑course turns.

Construction & Fitment

  • Billet aluminum body for maximum strength and long‑term reliability

  • Black anodized finish for corrosion resistance and a clean, race‑ready appearance

  • Direct fit for Yamaha SuperJet (1990–2020) using aftermarket mounting systems

  • Compatible with Kawasaki 800SXR only when used with a UMI handle pole. Not compatible with Kawasaki OEM handlepole

  • For use with aftermarket steering mounting system UMI Racing JS‑04103

Why Riders Upgrade

As stand‑up skis age and horsepower increases, the stock steering plate becomes a known weak point. Flex in the front end leads to vague steering and inconsistent feedback. The UMI billet turn plate locks the system down, keeping steering precise even through hard landings, loaded corners, and aggressive surf riding.

If you’re installing a UMI pole, switching bars, or rebuilding your steering assembly, this turn plate ties the entire front end together. It’s a smart, high‑strength upgrade for riders who want dependable control and race‑level precision from their ski.

NOTE FOR Kawasaki 800SXR: This mounting system and turn plate only fit the UMI Handle Pole. This kit does not fit on the Kawasaki OEM Handle Pole.
