Hi Guys , running an EFE with 1100M complete rear end fitted. All works fine , but just looking to upgrade again to maybe 750Srad swinger or Gixer1000 K1 K2 . Something that looks a bit beefier. Prior to taking endless measurements , just wondered if anyone had upgraded to this mod ? Is the 1100M rear wheel same as a later K1 K2 ? Swingers are cheap to buy but need to use as many existing bits as I can. Any help greatly appreciated. Been away awhile , so not quite a newbie !! Gaz
