There have been a handful of times where my car was broken down, and I only had the bike, but I would never by choice only have a motorcycle.Unless you're in a situation where you don't have to drive much (live downtown apartment, college campus, etc.), I think its very unwise. Simple things like going to the grocery store are a hassle when all you can transport is what fits on your bike.I would either buy a cheap car, or sell the Raider, and buy an equivalent cheap bike and cheap car.No point in riding a $10K bike if you don't have a car. I'd rather have a $5K car and a $5K bike.
Sorry about the marriage. That's tough, no matter how or when it happens.This is gonna sound like your grandpa, but there was a time (30 years ago) I rode my bike year round. Home-work-school-home was 89 miles a day. I used a coverall like they use for snowmobiling with a full-face helmet, gauntleted gloves and insulated boots. I rode home in snow and ice...it wasn't fun or pretty but I had to do it because my wife had the only car we had. As soon as we could afford it, we got me a car. Good luck with everything.
