Its usually much higher to ride. Unless U have a small 250/440 cc Honda with small tires and get 75 MPH going only 15 miles/day.
Motorcycles are like machine guns; a lotta fun , But, don't whine to me about ammo costs.You Knew it had a cyclic rate of 900 RPM when you Bought it.
My tires, I am lucky if I can get one for $100. Easily up to $240 , Each, many don't last over 8,000 miles. My MPG varies from 30-47, I am supposed to use premium ( $3.65/gal) I am constantly refilling her 4.7 gallon tank with the 34 mile commute M-F, plus runs on weekends. And I use $$ synth oil, about $40 just for oil/filter for an oil change every 5,000. Not including primary oil . Dealer wants a Fortune for basic maintenance. Only a few shops in town will Touch a Harley. Like I have a Rolls or something. Now at only 30K, I'm told to inspect primary and timing chain.. $200 for dealer to do it.
My car, if it didn't leak, could go 7500 on synthetic, gets 43-50 MPG freeway , takes regular, and has cheapest tires on earth that crack up from age before they wear out. Can go 50K on Michelins, as car is very light. Maintenance not too high; any shop will do it. Much competition. I do it myself. $14 for timing belt every 60K, Vee belts are very cheap.
EDIT: Thumbs Down? Have you Seen our roads? A scandal. More tax $$ to Prisons than even to schools, cops...or, roads.More glass in Pima County road asphalt that most of US. Cheap $74 tires, Yes, 8,000. A $240 Michelin "commander" is Supposed to go 10 grand, but, We''ll See. Our 116 degree summers don't help with tire life, either. I have been riding over 20 years; only in So. AZ have I had to change Any tires. Anyone have an issue with the truth, comment me directly; don't bother others. This is chicken-****. Bikers don't do this . ID care if you email, just be civil and have evidence. I Do. I can get statements from every bike shop in town, receipt. I will not accept anyone's words, alone, not even from 5,000 miles away.
