This may sound unusual coming from someone who loves wheelies and burnouts but I don't see any need for clutchless shifts. I know that done properly there is little or no chance of hurting the transmission but I do not see any benefit from the technique (as opposed to the vast and immense benefits of wheelies and burnouts!). Perhaps in circumstances of competition where tenths of a second matter I could see the need but not for everyday riding. If you wish to utilize this technique for your own pleasure then good on ya, mate!
