Why Titanium Grade 5?

Grade 5 titanium (Ti-6Al-4V) is the most widely used titanium alloy in aerospace and high-performance applications. It offers an excellent balance of strength, corrosion resistance, and low weight:

• Strength comparable to many steels at roughly 45% less weight
• More elastic than steel
• Highly resistant to salt water, perspiration, and acids
• Non-magnetic with a very low magnetic signature
• Excellent fatigue resistance and durability when properly installed

Designed specifically for the Ninja 500, the Wurx kit is a straightforward way to reduce unsprung weight, improve long-term corrosion resistance, and give the bike a sharper, more refined look.
