hub width.

Hey guys I am designing a bike of my own and my design calls for a 210mm wide rear hub (nut to nut) do any of you know the technical spacing on your front and rear hubs? I am looking for hubs i can just slap on the bike instead of having a rear hub custom machined. As for my front end it will be the same forks and wheels from your bikes with a 4+" tireThanks for any input you give i appreciate it.

The hub width is not equal to the inner width of the swingarm; all bikes I have worked with use spacers to fill in the difference. So your question on what the width of the hub is nut-to-nut is not well defined.

In any case, the width of the hub itself is 100 mm for the front, and 152 mm for the back.
