From what I have seen, motorcycles have just parked wherever they want but there is a huge parking lot. There is also parking at the Baryessa BART Station and it might be a safer bet although they charge. You could also ask them to bring it inside as it is an easily accessible area for motorcycles if you are creative.
Yeah what he said.. I don't really go to San Jose much so I wouldn't be able to answer this question..sorry
