$30-40 for a decent front/rear or even just rear Cyclone is Definitely worth it for the upgrade if you're looking to stay with what the bike came with, which I would if the bike is in immaculate condition. My ARX bike Sucks compared to the Cyclone I used to have, which also happens to be the bike khatfull was referring to that he polished up incredibly well. If yours is really in that good of condition, here's a few pics for inspiration of what khatfull did with his and you could do with yours. It's a beautiful bike and a great rider.
