I have two separate motorcycle policies, with 9+ and 6 years - I typically use the higher for a touring bike and the lesser for Sunday rider.
Due to Covid, I've been using a Bonneville T100 exclusively.
Last year on the 9+ policy was £67, this year on the 6yr policy is £73 - both 3,000 miles protected NCD.
I recall a couple of years ago I had a BMW K1200R Sport on the 9+ for around £97, same cover.
Age, location and secure garaging make a big difference.
