My honda NC750 at 10 years old cost me $4200. I had to replace wheels once (rubber, $600) and the transmission failed on me ($850) all within my first 8k kilometers.
My last car was a Subaru forester that did cost a little less, was older tho, on that I spent about $800 in total per year on to keep it alive, easily doing 20k kilometres a year.
Motorcycles arent so much cheaper necessarily.
You got scammed if by rubber you mean that 2 motorcycles tires cost $600.
NC750 is 750cc. Very big super costly bikes are an American thing. Third world works perfectly fine with a 50CC - 150CC for under $1000, to a super premium bike 300CC if you want to show off.
You always have the option to spend more. America has this macho bike person stereotype to live upto where you must buy a bike close to 1000CC.
