The 18.8/27 set induces a lot less under or a lot more over depending on how you look at it. It's a set up that an A/X'er might want to induce quicker turning on a short tight course but a big track guy would hate because of it's high speed twitchiness.

The thing to keep in mind besides over/under steer characteristics is that the higher the wheel rate the lower the mechanical grip, the sole reason to use higher rates is to minimize the geometric changes seen in a loaded suspension,

Help me out here. When looking at the 26mm rear bar specs, the percent looks off as does the rear wheel NM rate. It seems like the 21/26 % should be less than than 21/27 rate. Am i reading this right?
