I am looking for a K75 atm partially because of you and your build. I would love to know more about your front fork set up. You mention that they are 45mm Marzocchi's off a GasGas.
Did you use the yokes from the GasGas too or did you modify the BMW parts? Also is that the GasGas wheel mounted up front?
One last thing for now, could you show the lowered shock mount?
