rup bars are better than fuzion bars (hands down)
fuzion forks might as well be made of paperclips and they're just hideous.
fuzion wheels absolutely suck
rup decks are 10 trillion and 8 times better than fuzion decks
the fuzion headset isnt horrible.. but its not very good at all.
the fuzion is a piece of crap with a ton of features. this is like buying a car, you could have a sun roof, heated and cooled seats, 10 million horse power, and a damn flux capacitor but if its only going to last 20,000 miles you might as well buy the simple little civic and hook it up to your liking, then you can be proud of your work and you will have a 20 times better scooter, and you can live with the fact that you didnt fall for a bunch of cheap ass gimmicks made to impress you for a little while.
so yea, go for the ultra pro, you will end up saving money in the long run even if you hook it up.
