I was in that exact same position last year with my old Beemer. Insurance was sky rocketing (no pun intended) and the amount of time I used it I thought about giving it up. Well, in a roundabout way i did. First of all I found cheaper insurance that was bearable, then i bought a new lid, a Kilo lighter than the Nolan. that was a weight off my mind

Then somehow or other bought new summer clothing, mesh jacket etc and i was a born again biker. Still one thing niggling though was the sore shoulders after a long ride so decided it had to go. Triumph Birmingham offered me a fair price against the Beast I have now and the rest is history, go out on it as often as I can

.
Think long and hard before you do give up on the beast, don't live to regret your decision but if needs must then thats what you must do.
BTW: my wife is very ambivalent about my bikes, has never stood in my way

sadly, (oops, did I say that out loud?) so her say isn't in the equation but if she tried to stop me i think I'd probably dig my heels in anyway. After all, she didn't consult me over here 3 Mazda MX5's over the years
Happy biking, hope you keep it, I love mine and no sore shoulders anymore #bonus
