I think it may be about time that I sell my beloved Z1000 After my third knee surgery, the last being in late April, I've had issues sitting for moderate periods of time with my leg bent at acute angles without having a fair amount of pain that creeps in. The greater the bend, the quicker it begins to hurt. Surgery was done to repair some cartilage and it prior to the surgery, I was having severe pain so surgery did help. It just wasn't a cure. I've been commuting the last month or so on my Z (~35-40 min ride) and about halfway through, I get serious a knee ache. I'm going to give it a little more time to see if it improves (it has, a little) but I have quite a bit of arthritis in my knee thanks to age and numerous injuries and that's not going away. It has bothered me for years but now it's worse to the point that it makes me not want to ride the Z at all. I had planned on getting something more comfortable anyway (i.e. maybe a Super Tenere) but I was going to keep the Z for those times when I wanted something sportier. Now, I'm not so sure. Maybe I should've titled the thread, 'what a drag it is getting old'.
