I have read about 100 different ways to calculate reductions of weight of the wheels. Most actual hard numbers I was able to find are car related. Im trying to find out the actual hard numbers on lets say a 1.8lb to 3.9lb reduction of weight on the wheels and how it equates to power gain or change in actual spinning weight? Anyone have a calculator or a simple equation in relation to motorcycles for only a few lbs of change?

Not looking to debate... just a simple way to put a numerical value on shaving some weight off of wheels/ sprockets/rotors etc.....

Thanks for any input......
