Money is one thing.
Crashing and never shaking the (ghost) is another. I've crashed twice at the track. It wasn't too hard for me to shake the fear however it did take a few trackdays to get back to my
PR times.
I've only known one person to simply grow tired of trackdays.
Club racing is the next step up. Kinda.
When it comes to giving up street riding I guess I have not made it to that point yet. I've crashed 4 times on the street since 2007(~60K miles). Three of those were motorcycle vs. deer crashes. The joy of rural Wisconsin.
Personally this is my 4th solid year of trackdays. First on a well sorted R11S. My progression went from the following.
2010-2012 Several TDs on the same track (home track)
2013 Lots of TDs at the home track plus many road trips to different Midwest tracks
2014 A road trip to CA to ride several different tracks
2015 Club Racing is on the agenda.
I budget around $3000 per riding season in WI for trackdays. It's going to get more expensive with the club racing though. I'm not sure if I'm a "race boy" though so I might be a one season deal.
