get me a rough measurement from front wheel center to rear wheel center. just lay a tape measure on the ground and eyeball it. already have a '96 LS400... wow really? i havent come close to finding that out. but you also have a early frame. the later ones are way better, im kicking myself for cutting up and tossing a C notched 78 frame right now. the exhaust cutout in the xmems is totally worth it. not sure of differences up front tho.
I'll try and have a rough measurement this weekend. I'm busy this evening; I will probably be able to get the measurement Friday evening, but won't get to post until Saturday.
