Insurance differs for each person... their age, driving record, location, where the bike is stored, etc.
I currently have the following insured with Geico...
2012 Triumph 900 - $320/year full coverage
2013 Honda CRF250L - $130/year full coverage
I just got off the phone with Geico regarding the Grom. They quoted me $457/year full coverage. LOL! I know it's classified as a "sport bike" but obviously something is wrong there.
My Triumph and CRF are worth $15k and are $450/year total, the Grom is $3k and they want the same amount?!
After being helped by 2 people they realized they may have not considered the engine size, top speed and total cost of the bike correctly and wanted to send it out for review and get back with me. I thanked them for their consideration and noted that I expect to pay less than my 250 for it. My Ruckus and Met were $90/year each full coverage so I will be comfortable around $110-125/year for the Grom.
I will keep you guys posted.
