I'm guessing it will be hard to part with the old girl after so many miles together . If you can afford it , you could put it away as an investment on blocks and carry on with just the Busa ?
Maybe , like you said , make the break , sell it on , better to have great memories than tainted with future , at best , possible potential headaches .
You do so many mile CBXRider that if you don't keep on the very top of maintenance , as you obviously always have in the past , can otherwise get you in potential problems . Then you also got wear and tear failures , all able to cause trouble , such as roadside breakdowns , in your case , often many miles from home .
This sort of motorcycle devotion is never going to be cheap , as you well know , but perhaps a new fresh ride would be another option to consider ? Or , the Busa gets a freshen up , ready to stack up many more miles of addictive ride , and you get to save a bit of $ from the sale , which is always a good thing .
At the end of the day , usually flesh and blood wins over machine , when it comes down to the hard decisions , so machines come and go in your life .
Good luck with your decision bro , not the end of your story , but another chapter , and hopefully we still get to share your experience through your excellent tour guide posts .
