How many miles before you trust a used bike?

Curious what the collective wisdom is here.

Warm core, warm hands - start with the liner.

Pinlock or fight the fog forever.

Depends entirely on the bike and the rider.

My back thanks me for that upgrade daily.

Bigger tank, fewer stops, happier me.

Take it easy the first thousand miles.

Solid advice, wish someone told me sooner.

Adding this to my list, thanks.

I check pressures before every long ride.

Two-up is a negotiation and I love it anyway.
