Bout 25mm if memory serves- 21Quest is more reliable on stuff like this

That's a lot, for an SV, but if you fit a 120/70 front tyre instead of the 120/60, it adds around 12mm of ride height so you're only down 10-15mm. I had my forks 12mm through the yokes anyway with the stock forks, so it worked out perfect.
Also, the increased rolling circumference means your speedo becomes more accurate
