The 2004 Kawasaki ZX-10R AMA Superstock racebike is more powerful than the company’s ZX-7RR factory Superbike.

That’s the word from Kawasaki AMA Team Manager Michael Preston. Speaking during testing at California Speedway Wednesday, Preston told Roadracingworld.com that his team’s ZX-10R Superstock bikes made “way more horsepower and way more torque than our 750 ever did.”
