Horsepower/ weight ratio = mph loss

If  hp = weight * (speed / 234)3



and a person is riding a motorcycle which weighs 627lb (wet)
has a 65cu / 1100cc engine with a
95 x 75mm Bore and Stroke and a
8.3:1 compression ratio, Motorcycle

How is it, that the addition of a small brass pin attached to a Club Pin can cause the bike to lose about 20mph?

How much does that small brass pin weigh?
