The NHRA release the brief statement below.
NHRA’s Vice President of Technical Operations, Glen Gray spoke on Vance & Hines’ excluse ownership of the Harley-Davidson V-Rod program in the Pro Stock Motorcycle class.
“There has never been a rule against it, and I will give you an example of parity just in other forms of NHRA racing,” said Gray, who was hired by NHRA in July of 2008. “With some of your big Top Fuel and Funny Car teams they make some of their own parts, like maybe a supercharger or cylinder heads or some things of that nature. They don’t make those parts available to other people either. It is not unique to just Pro Stock Motorcycle, and there has never been anything in the rulebook against it. (There is not a rule) that says you have to make parts available to everybody not since I have been here (at NHRA).
