I used to have a near perfect, 100% unmolested, bone stock black Skorpion Sport Cup; no longer. I just made its only modification: a center stand. Now I can adjust the chain, change/check tires and so much more w/o trying to find an unused rear stand kicking around the shop - why on earth don't *all* street bikes come with center stands?
For those interested in doing this, you need to locate a non-sport Skorpion center stand, the bolts that hold it on, and the double spring setup. These pop up on eBay regularly for cheap - 20-30 bucks. You then have to carve a good chunk of the right side lower fairing off, and a little bit of the left, and then it bolts right on! You can't tell that anything has been carved off the fairing when you're done - it looks completely stock. Why they didn't come this way stock I don't know.
