Honda doesn't list a recommendation for miles or age in the service manual, only the removal/change procedure. 60k is plenty I'd say, and certainly not more than 8 years. Just removing the covers can tell you lots about the condition of them.
I recently purchased a '99 with 110,000 miles on it. The timing belts had never been changed, and I was asking the same question that you did. I think the previous posts have answered your question. I just finished replacing the belts on my bike and I am now experiencing greater peace of mind. I've had some bad experiences with broken timing belts on cars in the past, and I've learned my lesson. Don't neglect this preventative measure. The consequences can be much more expensive.
