Re: what would you consider high mileage?
 

The higher the mileage, the more important the current owner is.

I have ridden some great feeling 100,000+ mile bikes, and I've ridden some 20,000 mile dogs.

That said the price has to reflect condition. Short of producing a recent Dyno run, compression test, and oil usage rate stats, it's best to knock money off as the mileage goes up to reflect the likelihood of components being past their best.

Re: what would you consider high mileage?
 

Depends a huge amount on the specific model you're looking at and how comprehensive a service history it has.

I wouldn't hesitate to buy a Goldwing or an R80G/S with 100K on the clock if I knew it had been maintained well. An R1, not so much.
