The original Yamaha tool was no good on my previous bikes. With the high-quality Vmax 2 gen I wanted to have something reasonable in exchange 1:1. And it should fit in the little pouch under the side cover and take up no more space than the original cheap Bleck tool! In addition, I will add a ratchet and appropriate nuts. Of course, the whole thing can be added to as you wish, it's all a matter of space and taste..... Carsten
