I need to check travel but I do have a set of factory forx. I bought them new, they are fit damper top of the line from bitd. From day 1 I swapped the lowers over to a new set that could run v brakes. I used them briefly on a retro bike running modern kit, but then reverted to more retro, including forks, so they have done around 50 miles tops. Still have the unused disc only lowers that I removed before any use. I did cut down the steerer slightly but it's still pretty long.
If you are interested I'll check travel and grab some pics. They are as new due to the low low mileage and that was all road use. 50 miles is probably an overstatement, probably more like 20.
I've resisted selling as it's hard to find modern forks with v brakes, but I don't have any builds I can think of that these would work on now due to longer travel than retro frames were designed for.
