Bore up's Piston is the Wiseco.
I thought so myself, but recently up-and-coming Manufacturers are catching up Rapidly!
I think the quality is very good, but the drawback is that you have to wait a long time to order parts for repair, such as Piston rings.

Because it is before use only for seeing.
Unfortunate point
First of all, PistonTop is a Cut-out scratch as it is. Forged Cut-out Piston is a kind of such a thing? Forged Cut-out Piston It's the first time. I will buffing myself. Edge should not be brushed!
If you touch the Edge of Skirt and Piston Pin's hole with your fingers, it feels like BALI remains slightly. I am going to lightly with a 1500 paper.
good point
Wall thickness around Piston Pin is considerably better than OEM
Since OEM 400 Piston's High-compression is safe!
Forged Cut-out is beautiful.
"I have a forged Cut-out Piston in my Engine," she can grin.
There is no 88 mm in YOSHIMURA.
It is considerably cheaper than YOSHIMURA so it has a sense of affinity.
