I almost bought it Jon, but I'm gonna wait and do either a no link or a cr250 link(whatever darn setup LSR uses instead of cr500). My LSR TT frame has a no link style top shock mount, but then has a linkage mount on the bottom(250r linkage fits it too). The PO of this frame just went ahead and ground down a rear shock to fit at the top. Must of worked pretty good cuz he won alot of races(yes he could ride). I have a -1 swinger i can use already. The back of pro peg nerfs have been cut off(with a flat aluminum plate rewelded) so a -3 will fit without rubbing anything. If this swinger hadn't been modded to the earlier style, it would already be mine. Good price tho and I'm still tempted, but I'll wait...
