Hey man, I bought a 2002 Yamaha R1 before Christmas and just started shopping around for insurance. I'm going to turn 25 in June, but I can't wait that long so I got quoted $211/month. Full G, no tickets/accidents, never got insurance cancelled or anything. I'm getting my M1 this week so I'm going to call again to see how much it will drop after my M2/driving course. They said if I wait till I'm 25 then it will drop almost $800/year!! Buuuuut I can't wait till half the season is done. This is also JUST for the bike, I won't bring my car over because it's almost 3 times as much as I pay now!
SF also said that they only renew motorcycle policies once a year so if I get insurance now, I'm not eligible for the 25yr old rate until next year

PLUS they said if I start insurance now but want to cancel it in Oct let's say, they will pro rate charge me for the rest of the year anyways. So either way your paying for a whole year of insurance...$211/mo even during winter
But all in all, $211/mo for a litre bike and a noob...not too shabby. Gotta pay to play
Gonna check out a couple more places, but I think I'll go with SF.
