back in 17 when I replaced tires on my Ninja I was sent a front tire from Revzilla that was 2 1/2 - 3 yrs old. I immediately called about it and was told that I could send it back (probably had to pay my own shipping) but there was no guarantee that I'd get a newer one as they did not check date codes on new tires they shipped out.
I kept the tire and it's now worn out, need a new set of rubber, but the tire performed just fine, no problems.
