[QUOTE="fts, post: 1690785, member: 50537"] Disclaimer: I do not know much about G1 or G2 suspension configuration, other than they use leaf springs. I don't have first-hand experience either, so all that is below theory and vaporware. The biggest advantage is not really that the G3 is using coil springs vs. leaf of previous gens, at least not directly. The coil springs' packaging is very small compared to the leaf string setup, and it allows for the multi-link (5-link in the case of G3) configuration to be used, which is similar to the TRX. It is this five-link configuration that provides for more comfort, better performance - meaning better chassis control - and versatility under different loading. Essentially, the new multi-link configurations allow the chassis to be controlled more precisely along each of the 3D axes. In addition, the live-valve shocks are different on the G3. On the G2, only the fronts had computer input for actively adjusting shock dampening, and rear shocks would get their cues from the fronts. That is not a good solution as there are always delays before the rear shocks could adjust themselves, they were just reacting. IMHO, that must have created some weird motion ratio mismatch between fronts and rears. On the G3, each live-valve shock is independent of one another, but controlled and adjusted centrally. This is a very significant improvement or [I]must be[/I] (since I don't have first-hand experience). [/QUOTE]
