its all opinions here. i personally like the two brothers x metal carbon fiber. i just like the unique carbon fiber design, thats about it. micron makes some nice quality pipes but i dont really care for the huge cans in a high mount thats why i went with devil sb2.
In Roadracing world, they have an interview with the guy who rode that RC51 that supposedly went 200+
He says he was going about 130 to 140mph. All he had were slip-ons and a few other cosmetic mods, but nothing big. No NOS, nothing. They dynoed his bike at a bike shop, and the bike shop said his bike couldn't even get anywhere near that. I think they said his top speed would be between 160 and 170 max.
Roadracing world talked to the traffic cop about the dyno results and all that, but the cop stands by his word that he did 200+. I guess he didn't want to look like he made a big math mistake by saying he went 200+. The magazine even has a picture of his ticket in it.
