Sorry for the delay in a review. I tried the collars with a few different set ups. I wanted to get a feel for them all and compare to see where each were. All setups include the Lightspeed collars, and different variations while using them. 1. Pro Circuit Link w/ forks raised 5mm- First off; I hated this. I literally scared me in every corner of the track. The front end was all too responsive and wanted to "knife in" every time I moved the bars. I rode about 2 laps with this and quickly came to change it. 2. Pro Circuit Link w/ forks level with clamps- The bike really felt the same as before, with the forks raised, but it wasn't as nervous in the corners. Still very responsive, and had the same knifing characteristics as previously mentioned. 3. Stock Link w/ forks raised 5 mm- The bike felt 10x's better than with the PC link. (I know the instructions say to run the stock link, but I wanted to try different settings and I already had the PC link on the bike.) It handled well, I wouldn't put it on par with a Suzuki , but the collars definitely helped the "light front end" feel that everyone seems to suffer with. 4. Stock Link w/ forks level with clamps- I went back and forth between the forks being flush and raised 5mm. Somewhere in-between 0-5mm i found to be the money spot. The bike didn't handle much differently as mentioned in #3. Overall, I'm satisfied with the product. It helps put just a little weight on the front tire, gives it a more planted feel and eliminates the tendency to guess whether or not your front tire is going to say "see ya" middle of the way through the corner. Do I believe that it is an "end all" fix for the 10-12 YZ's? - NO, its a bandaid fix at best. It helps, and if your willing to play with suspension clickers and fork height adjustment to find that sweet spot it very well be the last thing that you do buy to fix the handling woes of your YZ.
