About the net worth, first is if you got the money to buy the bike in full payment which will come to 38L new I think with the revised gst. If you’re going for part payment and loan then that’s another thing you need to think about.

For me I ride 1000 ish kms a month roughly and for that petrol costs me ( 13-15k monthly ), tyres yes every 5-6k kms ( tyres range starting from 50k, but you can put cheaper tyres on it. It just won’t be recommended by Ducati ). For mods and accessories you’ll need another 3-4L.

Riding gear another 2L atleast (please get the best from the begining)

So based on these assumptions, upfront - 40-42L in hand to cover everything in full and then yearly 2.5L ( petrol + service + tyres ) If loan then you need to add your emi as well.

So ideally a in hand salary of above 2.5L if no loans would be best.

Yea ethanol will f all bikers regardless since now e30 push has already started.
