I am looking at this now. On previous trips to the USA I just went into a local bike shop and brought it over the counter.
Not sure what level of police presents on the road you are used to, but in the USA it is high and I always manage to get stopped and have had received a speeding ticket so it pays to be legal.
I had a quote from Fernets for $140 for 2 months which is they limit on non residence insurance, you can renew after 2 months. The web page states 3 months but that has changed.
The 2nd quote from

She is an agent for Acord insurance and has quoted $200 for 4 months. The quote process is long winded.
For Canada you need interstate insurance with a minimum of $200,000 liability.
I will try Progressive today.
All the best.
