Did Kawasaki Miscalculate the Tyre Setup on the 2025 Z900?

The 2025 Kawasaki Z900 continues to dominate the conversation around first superbikes in India. Its aggressive styling, smooth power delivery, and approachable ergonomics make it a natural next step for riders coming off 300–400cc platforms. But one point that’s quietly raising eyebrows among experienced riders? The tyre choice.

Kawasaki ships the Z900 with Dunlop Sportmax Roadsport 2, a high-performance supersport tyre meant for aggressive road use and light track riding. The S22 is sticky, confidence-inspiring, and offers incredible grip under spirited acceleration and cornering. But here’s the catch: it wears out quickly. And for a bike that’s more often used on Indian highways and weekend rides than on racetracks, that raises a valid question: was this the right tyre spec?

For newer riders, the Sportmax softer compound can be unforgiving in the long run. Many find their rear tyres squaring off under highway use or showing early signs of wear well before hitting the 6,000 km mark. Unlike track surfaces, Indian roads with their inconsistent tarmac, heat, and debris aren’t kind to supersport rubber.

Given how the Z900 is positioned not as a track tool but as a real-world naked bike, a sport touring tyre might’ve made more sense. Options like the Pirelli Angel GT II, Metzeler Roadtec 01 SE, or Michelin Road 6 bring better longevity and more stability in wet conditions and still retain solid grip for spirited riding. More importantly, they’re built for mixed-use city traffic, open highways, and unpredictable monsoon stretches exactly where most Z900 owners find themselves.

This isn’t to say the Sportmax is a bad tyre. But its use on the Z900 feels like a spec-sheet win rather than a real-world choice. For a bike that's become a gateway to big-bike ownership in India, this might be one of Kawasaki’s rare mismatches of performance rubber on a platform that’s more tourer than track monster.

Riders upgrading to the Z900 are already adjusting to more power, electronic aids, and heavier handling. Throwing in a fast-wearing supersport tyre only adds another learning curve and an early trip back to the tyre shop.
