I know the quick turn throttle tube is not a very cheap mod, especially when you add the price of grips and shipping = $100+. But, I can say that it is the single most noticeable mod I have done, and in addition to the much shorter throttle throw, the smoothness and solid feeling vs. the stocker is light years better. I mostly track ride my bike, and with the stock tube I would have to overgrip or regrip just to get full throttle coming out of a corner. Obviously not the best technique for speed and smoothness. Yes there are cheaper eBay options, but you will not regret spending the $100 on this mod.
