Description

Variable Ride Height Adjuster
Kawasaki Ninja EX400 / Z400 / Ninja 500 (2018–current)

Spears Racing’s patented Variable Ride Height Adjuster lets you raise the rear of a stock Ninja 400 / Z400 / Ninja 500 without buying a new shock. On a track-day or race bike it also lets you change the installed length of an aftermarket shock.

The insert can be fitted two ways on the stock shock:

  • +5 mm (hole on top) vs. stock
  • +10 mm (hole on bottom) vs. stock

Installation is a straightforward shock-mount swap and typically takes about an hour. The bracket is laser-cut from mild steel and replaces the OEM Kawasaki mount.

Ride height and swingarm angle (stock Kawasaki shock)

Setup Swingarm angle Ride height change
Stock OEM shock 9.5° Stock
Adjuster at +5 mm 10.3° +10 mm
Adjuster at +10 mm 11.3° +23 mm

Street riders can add rear height and change chassis attitude on the factory shock. Racers can use the same mount to fine-tune aftermarket shock length and swingarm angle.

Spears Racing has designed application-specific race parts for decades. This adjuster was developed and tested to replace the OEM bracket with a precise, repeatable mount.

  1. Adam Faussett –

    Great setup. I’m using the +10 and the tock shock length so I still have lots of adjustability left.
