well - to help out then. Entering street riding and 180lbs you get the attached. Doesn't account for two-up but in my simple mind I'd figure that the extra weight is distributed so that it wouldn't cause a major issue for the forks.

Many thanks guys

one thing that they do not mention is the oil weight, which is just a step above water from stock and you should think about getting some heavier stuff when you do the swap over.

I went with 15 weight oil in the forks and love it wholeheartedly! I found the stock setup very jittery in corners and over bumps and the heavier oil settled that and gave it a much smoother and planted feel.

I weigh 160lbs. I have the 1.0kg springs and love them.

I also got the emulators because if you're going to upgrade - do it right and get the works.
