That is an interesting perspective. When the frames changed, not only longer but with the cross-braced front and rear subframes and lower braces across the gearbox (along with the wider rear wheel/tire), the thinking was that this was all in response to persistent complaints in the press about the odd handling characteristics of the early Sports. While some of that was down to "expectations of what a Guzzi handles like,' there were a collection of very real issues that affected the early Sport's stability and tendency to "weave" at high speed in a cross wind (like passing a truck on the freeway).
It occurs to me the LongFrame was introduced for the 2002 LeMans, still with the early tank style (external pump/fiter), while the Gen2 tank came out in 2003, if I am not mistaken (?)
