the rear is very easy, there are a couple of options.
On my old Cadbike 31 I relocated the lower shockmounts
on the swingarm, on this bike I simply replaced the stock
12" shocks with a set of new 11"shocks. Shortening
the shocks 1" lowers the rear of the bike about 40
mm. Front suspension is a lot more work, I had ordered
a Burly lowering kit but somehow got the wrong set. Looking
at how the lowering kit works I figured it would be easy
enough to just make my own set.
