At 68,000 you are just getting started.
I traded off my 1990 at 55,000 and it was still running perfect. Because of the age not the mileage I would check the belts. Be careful and don't get the new one's mixed up with the old one's.
In the front of the alternator you will find 6 I think rubber bumpers, Replace these, the cost from the Honda dealer is around $16.00.
Make sure the rear splines have been greased. This usually takes place during rear tire service.
If you are not familiar with the service history, change all the fluids including the brakes, and clutch hydraulic fluids.
Pay close attention to the fork seals, there is no specifice time frame to address this issue, If and when they began to leak it is no great problem to make the repair. Look on ebay and pickup a service manual, around 40.00 this is a good price plus shipping.
There are other maintenance items that will need to be addressed but you will see them in the service manual, nothing you can't handle.
Ride safe
