Centre of eye to centre of eye is close to 290mm. There are already a few options out there. I have the M Shock and it has made a big differenceCan someone tell me the size of the original shock ( eye to eye ) as I will be getting a Scrambler around September ( to put the the shed with the Triumph 1050 sport ) to keep it company ! I am looking at buying some accessories prior to getting the bike ( a suspension place in Australia IKON is working on a rear shock for the Scrambler at present, I know the owner , he told me the other day ! , he exports around the world.
