While the RD400 might be better suited to our sister site, they've graced the pages of RSBFS from time to time with positive reactions. This one is in California and is advertised with only 8.1 miles. Unfortunately the pictures are terrible but I suppose no one is buying this sight unseen anyway. But if you want an instant new-old-stock collectible, this should fit the bill.
from the seller:
1979 Yamaha RD 400 Daytona Special. Motorcycle in immaculate condition. Original 8.1 miles. This beauty has never seen the California roads. Original dealer in Berkeley, Ca did not retail or registered. Motorcycle has been stored and preserved for the last 35 years. This is truly a motorcycle that has been in a time capsule for its entire life. Must see to appreciate. Condition on this motorcycle is one of a kind, an investment that is going to grow and can be passed down for generations.
We are looking for the right person that will give this gem a good home.
