Yeah,
I'm 6'2 and I've had some luck with finding jackets in a Tall or Long. I wish Triumph would offer their leather jackets in a Tall or Long as well. They've got some really nice stuff but the sleeve lengths are just a tad short, and I'm 6'2 not 6'5.
I think a good choice might be a cutom leather such as Vanson or Dianese if you got the dough.
My winter riding jacket is a.....ah....well....a Harley Davidson FXRG. It's "water proof", well built, nice features. It's heavy with good armor in the spine, shoulders and arms.
The Harley name is very subtle, it's embossed into the leather and you can see it only if your looking for it and then there's the FXRG Tag on the right breast. So not too gaudy.
I was able to order it in a Tall, but the jacket was very pricey, and it's way too heavy for summer riding.
