Alot of Yonex rackets have words SP, TOUR and some other words behind
I dont really see the difference between a Carbonex-8, Carbonex-8 Tour, and Carbonex-8 SP.
I've used all 3 rackets i dont really feel the difference.
can anyone tell me about that?

Yeah, they are different words :D.

Just try out the racquets and tell us if there is a difference ;).

i tried they all felt similar, the only difference is the color which i wanna say Yonex Carbonex-8 SP is REALLY SLEEK
the color changes under different light

hahaha, it's more likely just to differentiate between the models of a racquet. Not sure about yonex, but for carlton racquets, the tour models are usually higher end and stiffer, hence recommended for more advanced offensive players. i don't think the meaning in yonex is as consistent, although i could be wrong ...

hmm, yonex sometimes is kinda crappy, i mean a single racket model as so many variations, and they nvr really stated the difference, somehow its the cool design or something that attracts people

Names like Tour denote models, SP denotes the Distributor or if SP forms a part of the model number then it denotes a specific model, i.e. Cab 20 SP made specially for Sunrise the distributor.
