Hi..
There are not much bikes with a similar displacement to harley's (i
am talking about the 88B V-twins - 1449cc) So, you can't really
compare, there are only a few makes that are v-twins, like Ducatis.
but according to my friend, he said that his fat boy is quite fuel
efficient...
Anyway you can check Yahoo! auctions or classified for 2nd hand
Harleys, if not , you can make a trip to Turf-city - Sunhog, a
2nd-hand harley dealer.
Feel free to ask any more questions, I will try my very best to
answer all..
"Regards"
Harley Hong
