So, to make this short: of course it's possible, whether it makes financial sense is a question that's much harder to answer and depends on the real cost you have for your car. I doubt I could use my bike cheaper than my A4.
But the other factor is lifestyle - meaning you might be happier when commuting on the bike and in some areas you safe time (commuter lane use, lane splitting). But you're also less safe. You'll have to balance all that for yourself.
While I agree 100% I think I'm just trying to convince myself to go ahead and get it, although I didnt think bout tires. I used to go through rears every 4-5k on my other bikes (I rode hard) I thought I would get much better life on an adventure bike with the right tire. TBH its gonna be a lifestyle for me. I've always been a two wheeler and I'm just happy when I'm riding. I just turned 40yrs last month and I feel old, I'm not doing anything that makes me happy and to be honest I'm miserable.
