I recently took a trip of about 250 miles and was interested to check the milage while at a somewhat constant speed. About every 100 miles or so I stopped to stretch and usually got gas. For the first bit, I got about 38 mpg.just did a trip and the 9er averaged 48.6 mpg with me (215 lbs) and about 30ish lbs of luggage. Not too shabby!
Automotive engines have also become considerably more complex in that period of time. Motorcycles are just recently beginning to use fuel-management technology that's on par with what's in my '89 K5 Blazer. The components that compose systems like variable displacement and variable valve timing, which are big guns in modern automotive fuel economy, take up a lot of physical space in the engine and are very expensive. The electronic components that manage these systems suffer the same drawbacks. And implementation of these systems in motorcycle manufacturing would very likely rule out the V-twin as a competitor. Where would you hang all that crap on a twin cylinder motor? And who would want one that drops to a 1-jug thumper when you're cruising?Something I've been curious about - my Toyota Yaris gets very nearly the same fuel economy as my bike. Why don't bikes get better mileage? I was talking to a fellow I know who has a 1300 VTX and his bike does worse than my car. Average automobile fuel economy seems to have increased significantly over the 18 year gap since I've been riding, but not for bikes. Why?
I'm assuming that's by the liter. And yeah, we Americans have enjoyed very cheap gas for a very long time compared to the rest of the world. We still do in all honesty.Don't complain about fuel prices - here in downunder we pay average $1.40 AU - equals to $1.50 US !!!!!!!!!!!!!!!!
