We recently purchased this bike used. It is a 1999 and has just over 85, 000 miles on it, but since it is a BMW, we know it's good for at least 3x that. It rides like it's brand new!
The suspension is adjustable, so when my husband and I ride on it together, we can stiffen it up. The seat is adjustable, so when he rides, it can be on the lowest setting as he is 6'6". When my 5'6" self gets on there, I put the seat on the highest setting. This maximizes the comfort for both of us and makes it a great bike for sharing. The windscreen is also adjustable.
There is a "glove box" on this bike. This reduces the need for a tank bag or back pack because you can put keys, wallet, cell phone, etc in the cubby - it's right next to the tank and it locks to keep it safe.
This is more of a touring bike, so the ride is more upright. This eases the pressure on my arms and wrists and keeps my back from getting sore. It still has the maneuverability of a sport bike though, so no worries of having the foot pegs scrape on the ground when you make a nice tight corner.
I only have one complaint - my husband gets to ride it to and from work every day and I have to wait until he is home with the kids to take it out.
