I have had a 250cc motorcycle for a couple of years in Japan, but that
was more than 30 years ago.  On several trips back to Japan, I always
bemoan the cost of transportation and getting around from day to day,
even when staying within districts like say the Kansai or Kanto
regions.  The next time I go, I would like to rent a motorcycle for
about a month, anything from about 50cc to say 250cc.  The thing is, I
don't know if there are places that rent machines.  I have heard that
maybe a car rental place have 50cc machines.  I would rent one of
those if that's all, but I'd really like to get something a tad
bigger, and maybe even a machine to ride two up.  If I can't rent a
machine I was trying to find out if it was feasible to buy a used
motorcycle for a month and then sell it by pre-arranged agreement with
the bike store, when I leave Japan.  Does anybody know if such rental
facilities are there, where and an idea how much including kilometrage
rates?  Or failing that, does anybody have experience buying used
motorcycles?
