About that - it's not as clear cut as you might think.

Here is a picture of a stock XJ600S spring and spacer, vs. Hagon XJ600S spring.

As the eagle-eyed will notice, the stock stuff is significantly longer, like a good inch or so. Difference is, the OE ones are much lighter springs, so with static sag considered (non adjustable) the bike rode significantly lower, despite having longer spring+spacer than the new springs. And then even worse with the biker's weight added.

It's much easier to close the caps on the replacement stuff!

Makes sense?

If you are thinking about the swap, then get the springs because they're cheap, and work around it using variable caps or custom spacers. If they're the same price as CBR springs, then just get the CBR springs off GF and save yourself the hassle.
