Here's a list of all offers I got for my bike:
tourinsure.de seems to offer motorcycleexpress.com insurance but obviously (minimum) liability only, there are no options listed in the downloadable application form. Compared to liability only by motorcycleexpress it is much more expensive.
Examples calculated from their current online forms:
Tourinsure.de:
2 months for Canada/US, liability only (Bodily injury US$ 25000 per person, Bodily injury US$ 50000 per accident, Property damage US$ 10000), for motorcycles from 1051ccm and above: 310 Euro + additional charge of 45 Euro + 3.5% charge for payment with credit card =>
367,78 Euro total
Motorcycle Express:
60 days for Canada/US, Bodily Injury/Property Damage Liability (Bodily injury US$ 25000 per person, Bodily injury US$ 50000 per accident, Property damage US$ 10000; additional to tourinsure: Uninsured Motorist Bodily Injury 25,000 PER PERSON/50,000 PER ACCIDENT), US$ 66 per month * 2 = US$ 132 + agency fee US$ 60 + 5% credit card fee => US$ 201,6 =>
165,32 Euro at current exchange rate
Geico:
Got the same information as Chris of Japan. Will only offer long term insurance (12 months).
Lions Group:
Did send e-mail to them. Even got an answer in German. They asked me to fill out their form:
https://www.lionsgroupinsurance.com/...ntragsformular.
Got a quote for 12 months insurance (all insurances are valid for 12 months the broker told me), valid for US and Canada. Liability to Others, Bodily Injury and Property Damage Liability, $500000 combined single limit each accident. Insurance company is Progressive. Total premium is US$ 106 for my bike, which is about
87,25 Euro at current exchange rate.
Thum Insurance:
Found another insurance company with an online form for foreign customers:
https://thuminsurance.com/international-insurance. They answered, that they can't provide insurance for a motorcycle alone, only if it would be insured together with a motorhome.
There are really big differences in the quotes!
