Sorry about the late reply, my shock came from Victory in Ashfield. Progressive Suspension comes from Rollies in Qld, but you can only buy them through a dealer.Hi Blumntman
I'm also a Highball rider in the Blue Mountains (Lawson). Can you tell me where you went for your after market rear shock - I'd like to upgrade mine but no clue where to go?
Highball is great (though mine is being repaired at the moment following an an accident on the M2) - get it back next week and can't wait.
