Not only in fuel, but consumables like brake pads, tires, etc. Motorcycles for the win.

Except for tires!

My recent estmate.

Operating costs (fuel, insurance, fees, maint.  Excludes purchase):
25 mpg car, well used - 0.24 $/mile
65 mpg 500X - 0.17 $/mile

Hmmm, I'll need to try this comparison - as I have a smaller car (1200cc) which does 40-45mpg (I don't commute), only needs a very basic service every 2 years and does 20,000 miles to a set of tyres, I think the figures will be a lot closer.....  :084:

Bike's more fun though!!  :001:
The Story So Far.........
2017-2019: 12000mls recreational use - 89.73mpg UK; 74.72mpg US; 3.15litres/100km

Hard to quantify, but certainly am important factor, especially if it means you get to de-stress after a challenging day.

The memory of the ride to work and home is worth something, definitely. It's nice to have good, albeit fading, memories to mull over. It's the same effect as a vacation, but can be refreshed daily.

To get total cost of ownership, add your OTD/distance to the operating cost. For me that is 7500 US $ (with gear) / 39000 miles or 0.19 $ for a total of 0.36 $/mile. That improves with added miles, obviously. It could be only 0.23 at 100000 miles. We'll see.

Just did my first real fuel calculation. Filled up at 200 miles and put 3.67gal in. Works out to 54.5 US MPG. That was riding more conservatively to see what the bike could do if I didn't ride it hard. Seems very low.

I have a chain that's in dire need or replacement., many frozen links, and my commute is up a lot of hills. This city has a lot of ridiculous inclines. Will swap out the chain this weekend and continue to test. 60mpg would make me happy.

Hey mate. Why don't you hop onto Fuelly and start an account? It's a great way to track your fuel economy and mileage per fill over time, and helps you form a view of what distance you can get out of a tank with different types of riding.

It appeals to the obsessive part of my personality... just wish that carried over to tidying my workspace! LOL

I'll check it out. I've been keeping track of my car fuel mileage for decades, but never bothered with my bikes.

That seems low. My overall average is 64.6, max of 74, and min of 52, miles per US gal. But, my average speed is only ~50 mph. I've noticed that just adding some speed, 70 instead of 60 mph, for the last 4 miles of my commute will drop mileage from 64 to 62 mpg. I would like to run a full tank at 70 mph to see the effect.

It does, although looking around fuelly shows that low 60s seems to be fairly normal. I wonder if the bad chain and mostly hilly city riding has a lot to do with it. I'm in fuelly now and will be tracking it through there. It's a nice app.

Is your bike mostly stock?  Or do you have the RR suspension upgrades?  Are you running street tires or off road tires?  Do you have luggage and carry much weight?

My bike is mostly stock except for a 22 Madstad windscreen and a 46L topbox.  Im running PR4s and if I keep it at 50 mph and lower while cruising small back roads I will see 80+ mpg US.  Running around 55 mph I get 70+.  However, running 60 mph it drops to around 65 mpg and at 70 mph its around 58 mpg.  A couple times running 80+ mph I would only get about 45 mpg.  Wind drag sucks!

I also see a significant drop in mpg when there is a lot of stop and go like driving in town.
