This advice only works on the newer models 01 and on. If you don't ride passengers or haul gear on the rear, swap sub-frames! The aluminum one from the 99-00 weighs in at a mere 4lbs 2oz, compared to the steel frames from the 01 and on bikes which pork out at roughly 11lbs. Just a thought for all you speed freaks. Or you could try a diet. Me personally wouldn't help much, I'm 6 feet 5 inches @ around 260lbs.
