Located in Libertyville, Illinois is a gorgeous 1973 Yamaha TZ250A. This bike has been meticulously restored to original specification and looks brilliant. The motor has recently been gone through and the seller claims it only needs tires to be vintage race ready. Vintage race bikes are attractive because they will always be competitive compared to a newer bike which will become out-dated. See this beautiful race bike on eBay See the eBay ad here
EDIT: This bike sold for $9,987 with fourteen bids on 07/01/09.
Also, avialable in Tokyo, Japan but listed on eBay U.S.A. is a 1980 Yamaha TZ250G. This bike is claimed to be completely original, only having one owner. Being an original bike, this one isn’t perfect but carries some patina and wear–especially on the left-hand side faring. Seller is located in the US and claims shipping isn’t a problem. See this one owner TZ on eBay here.
EDIT: This bike failed to sell on 06/27/09 with zero bids and a starting price of $6,000.
