That's true for 1977 and later XS650's (earlier had 34mm fork tubes). I believe XS650's also have a slightly taller fork stem (triple tree) and probably longer fork tubes as well. If that's correct, you will have to use the SR500 triple tree but there's about an inch between the upper triple (crown) and handlebar and you can slide the longer forks up to compensate for the longer length and keep your frame geometry the same.

You probably ought to ask about the length before buying. Yamaha made XS650 Specials which had different wheels and might have had different forks too.

35mm forks are interchangeble between the 2 models. The steering stems are different. You can look up the part numbers here . www.yamahasportsplaza.com/pages/parts/viewbybrand/default.aspx
When you get the part number plug it into the part number search on the right side of the page and it will tell you all the models that part number fits.

Yeah, fork tubes and lowers are same pn for both bikes.

Just FYI, XS650 standards and specials had the same forks, but they only co-existed for 78 and part of 79. (Then the standard was replaced with the Special II.) But the same forks were still used up to the end of the model.
