Did you look in to upgrading anything else?
The $250 bet that you won't wreck your $5000 bike (that's probably what insurance would pay you in a write off) is your call, but I'd pay the $250.
I have an additional package added that covers my loss of work wages at %70 up to $700 max payout weekly. That was increased from $300 in the base package. The upgrade included a bunch of other things but it cost me $400 for the year.
Now, if I'm in a motorcycle accident with a car, it's highly likely I'm going to miss AT LEAST 1 week of work. More than likely miss several. One week of wages reimbursement and that bet is paid for. That's not including the other medical coverage increases etc. included in the $400 additional package.
Something to consider especially when you're new and more likely to make a mistake and crash. I crashed (no cars - my mistake - also didn't claim it and fixed the bike myself) but thankfully landed in tall thick cushy grass.
