    Yeah that' gonna be a long shot. Might have easier time with a Harris or Heat Magic....maybe.

    whats the 411 on that part? I have a trac arm on my 2005 bike and its really nice, light & stiff. Is the Yosh one super light or something?

    I think in the case of the K5/6 as the OP is asking about, the Yoshimura arm is longer because the OEM arm was too short to get proper geometry set in SBK. Even SSTK guys were running the axle all the way back as far as it would go to increase mid-corner stability with the OEM swingarm. They also can engineer different flex characteristics into the arm....not sure if that's part of what is in play here. Not super light to my knowledge.

    I have a buddy who has an 05 with an modified by Yosh stock swingarm, some minor bracing and its 1.5 inches longer is all that was done to it.

    Seems that's the general consensus when it comes to aftermarket swingarms these days. Even in MotoGP from what I've read those bikes have generally longer wheelbases than you would typically find with most sport bikes. I know more recently it appears to be the thing to do with the latest gen R1 to lengthen the swingarm. I remember glancing at Jake Gagne's initial SSTK bike and you can see how far back they pulled the axle in the blocks.

    ...and more recently teams are just welding in longer axle block extensions to lengthen even more.

    I moved my axle back via the chain on my swinger after seeing this thread and it made me feel more confident with the back end. It was much more stable than previous settings!

    Good stuff!

    If you never watched this video before (actually his whole series on there) you may find this rather interesting.
