Buying Guide
- Riding style matters: Choose Rosso II for balanced sport/touring, while Rosso IV targets aggressive supersport riding with improved lean and wet performance.
- Front vs rear emphasis: If you ride mostly on the front tire, prioritize a tire with precise turn-in and consistent front-end grip. For rear-heavy riding, select a tire with strong mid-corner grip and stability under acceleration.
- Rear size compatibility: Check your bike’s rear width and swingarm compatibility before selecting a 160/60, 190/50, or 190/55 rear.
- Weather handling: Both Rosso II and Rosso IV perform well in wet conditions, but Rosso IV often emphasizes wet grip and lean stability for sport bikes.
- Longevity vs grip: Dual-compound technology in Rosso II provides longer wear with softer shoulders for grip, while Rosso IV focuses more on peak grip and lean capability.
