Wouldn't you think sportsbike riders, who seem to me rather more likely to be riding at the jagged edge, would be the ones who really needed thick, well-stitched, leathers? I don't know, but I'd guess that sportsbike riders have more spills per mile than Harley riders...+1 on the LeatherUp.com quality. We ordered a couple of leather jackets from them after seeing dozens of "oddly positive" review (I now think that they are faked reviews).
Returned the jackets the very next day for a refund. Cheap and thin leather. Poorly closed seams. Velcro wrist and neck closures (instead of zippers).
Probably perfectly acceptable quality for the occasional afternoon/weekend sportbike rider, but not for serious use.
