Pros and cons

Pros

The stated model range and no-trunk configuration give Ninja owners a specific starting point for checking fit.
Adjustable buckles and a drawstring provide multiple listed ways to secure the cover.
Vent openings and reflective strips are useful design details for a covered motorcycle stored outdoors.

Cons

The cover must be matched to the motorcycle’s measurements, so the model-name compatibility list alone may not establish fit.

Customer feedback highlights fit, quality and coverage, including a report that the cover goes on quickly and one mention of use on a 2006 Electra Glide Classic. Those impressions are encouraging for convenient coverage, but the Harley-Davidson example does not establish fit on a Kawasaki Ninja. The overall ratings lean positive, while lower-star ratings indicate some varied experiences without identifying their causes.
