I swear to god, I may be crazy, but it feels like I have gained weight from this flywheel. After you add the counterweight, it weighs just as much if not more than the factory flywheel. From what Ive seen though, the stock flywheel weighs around 27lbs. The Streetlite is supposed to be I think 14lbs, plus the counterweight at maybe 4 or 5 pounds. So it should be much lighter but just from feel I swear it weighs more
