Let's talk... Ironhead Sportsters
I equate Harley-Davidsons too old-school muscle cars. Loud, obnoxious, and fun with old school looks but definitely just a cruiser when it comes to Highway use.
Sport bikes I equate to Formula 1 race cars. Really fast, awesome power to weight, handle very well but you sure as hell wouldn't want to take one of those on a long distance ride.
