For Racing Cylinder Heads We Use Copper Beryllium Seats and Titanium Valve Set-Ups, These Are Softer and Lighter Parts, So They Wear Faster, But Provide A Very Powerful Performance and Increase Acceleration. This Set-Up Is More Designed For Pure Racing, If Your A General Purpose Rider We Do Recommend The Standard Set-Up of Stainless Steel Valves.
