When I bought my bike used it had a set of grips with knurling on them sort of like that (the shape of the grip was a lot different though). The knurling wore out a new set of Harley gloves in about two months of light use.
I think those look great, but have no experience with grips like that. They just look like that would eat your hands up. It seems to me that withoutsome type af damper between your hand and grip (rubber, leather, etc) metal grips would be harsh.......i mean awesome...i mean harsh......awesome...ah hell just get em and tell us how they work!!!
