If you stand with your back to the saddle, bend knees then grasp the bottom of the saddle from behind you is should be easier to lift. I've had the same problem myself and found that method to be much easier than trying to lift it while facing the bike.
cavalry has just left, my hubbys work mate whos on a rest day came and rescued bessie shes now in the back garden and out gardens look like motorbike dirt tracks. Small price to pay! thanks for all your help, you physically need two people to lift this bike as its sooooo bloody heavy. Now if it had been his ccm or the other sports bike he owned in the past i would have no problem!!!
