I had T-Rex sliders on my '03, sold it to my brother-in-law, who crashed it on it's right side at perhaps 20-25 mph. The spool on the slider took a bashing and grinding but clearly saved some damage, though a hole was ground through the fairing lower. In my view, these do minimize external and outboard damage but mostly serve to protect the really expensive stuff: engine covers, cases, frame, etc. Interestingly, when brother-in-law was restoring the bike, his shop guy put the damaged (Delrin?) slider spool on a lathe and cleaned it up. My '05 came with Tip Over Guards (TOGs) which are wimpy and mainly for protection in a no-speed drop. I added T-Rex Sliders to go with the TOGs. I have had a no-speed drop and the set-up meant paint scratches only. Always a good investment.
