Cheaper until you realize the odometer rises a lot quicker than a cars does and tires are tied with fuel for the biggest expense, they aren't cheap and wear fast. The fun is worth it though, bikes rock, sold my last motorcycle last month and bought a bicycle to replace it. but motorcycle ADD kicked in and I wound up committing to buy the bike that got me started with motorcycles, a '95 kawi ZX11E project bike that I'm not going to get around to for a while.
