If you never own a YS, you'll never know the true value of them. They really are superior to all the rest both in power and value.
YS63 is the same power as a Saito 82
All that said, when you compare the power/weight ratio, they are much closer.
Yes, much closer. But the saito 82 weighs less than the YS 63. So, saito has better power-to-weight ratio. Now that might change with the new YS 70
