I'm trying to find out the distance between the mounting holes on Buell X1 and S1 forks if they're different. Can anyone here help a brotha out? Big picture I'm trying to piece together an inexpensive inverted front end, and I have lots of leads, but I'm trying to research some fitments. Thanks

3.5" on the S1 brake mounting holes.

Thanks CJ. you wouldn't happen to know what that is in mm, would you?

nevermind. 88.9 mm. Dang. so ducati brembos are out.
