thats sayin something about harley performance. Hope they do well

The Harley's have been kicking ass and taking names for years.. The sanctioning body made Harley Add 100 pounds of ballast, and then the japs became competitive. Then Harley found some more power, and again they're walking away with it.

Amazing how 2 little cylinders at 45 degree angles can produce so much power.

From the NHRA page, no mention of V-Twin displacement limit.

Pro Stock Motorcycle
Pro Stock Motorcycles have differing weights depending on engine combination - 575 pounds for Kawasaki, 590 for 92-cid Suzuki, 615 for 101-cid Suzuki, and 615 for Harley-Davidson and V-Twin, including rider - and have a maximum wheelbase of 70 inches. Bikes must be 1998 or later models and retain their stock appearance, including a front fender, simulated headlight and taillight, and manufacturer identification on both sides. The engine and body make must be the same. All motorcycles must pass NHRA body inspection prior to competition.

160 for v twins over 45 degree, 45 degree is 200cubic inch

If all things were equal the Japaneese bikes woulds still be kicking our tails!
