Was looking to get some advice on buying a 2014 Zx10R with 50,000 miles. He wants 4500$. Only reason I lean towards buying it is because he has paper proving a new transmission, valve service, leak down and compression tests, motor being looked over completely, and full tune up within 5k miles. For the bargain price anything I should be worried about. It will be a street only bike with the occasionally twisties thrown in, but mostly commuting. Also has a year left of factory transferable warranty. Thanks for any feed back.
