Hmmm. Some motorcycles (and some cars too, now that I think of =
it...Porche? BMW bikes?) use liner-less aluminum cylinders. The term =
Nikasil comes to mind. I had a race bike in the late sixties (a =
Kawasaki) that had a chrome-plated aluminum cylinder. I used to buy =
replacements by the dozen....

Aluminum does have a coefficient of expansion greater than the =

they design for aluminum. Aluminum blocks are becoming more popular for =
one reason; weight.
(And vehicle weight is the major player in the quest for greater =
mileage)
