Well, I wasn't necessarily implying vintage. I don't know if one can still do this, but I know my Uncle got fed up with his 430 Husky being jacked up to the moon like they come, and fortunately the shocks give you five different height settings to choose from. His is set at the lowest, and when I looked, it appears mine is set at the second-highest (the bikes are one year apart so the frames and shocks are identical.) He also has the forks raised up a bit in the triple-clamps, which not only reduces his travel (which he claims not to need) but also reduces his rake angle. If you lower the shocks and kept the forks the same, the rake angle would start to look very Peter Fonda. It has a very noticeable effect on seat height; our two bikes look very different size-wise next to each other.
And it sounds like it's someone you wouldn't necessarily want to do because you also encounter fast whoops (there are a few trails out here that have some big ones, which you haven't really seen in-video yet because the whoops are about as friendly to the 120 as AC/DC music is to the Pope.
But anyway, I'm still curious to know if peoples' shocks today have different settings for where to put the spring, or another way of directly changing the seat height. I'm guessing the forks are still adjustable in the clamps, yes?
