Looking at yours, it looks like you went quite a bit shorter, and lower than I'm planning to go... Just by looking at how far forward your shocks are, and how low they are on the swing arm.
But, yours is real, and mine is just a photoshop, so...
That said, my plan is to use the shock length and angle as the main thing I build. The upper shock mount will end up just about on the furthest corner back of the stock oil tank.... That is the plan anyway.
Have you seen that DMW bike? I have a pic on my phone, but I'll try to find the build pics of it online.
