I have RAC which covers me, gets me and bike/car home or to where I'm going, costs about £70 a year, not used it in 3 years but I get the basic bike insurance as some breakdown cover is upto 12 miles to nearest garage, then what? so what I save on insurance just about pays for RAC, Just seen on facebook a bloke left his scooter in a layby went a mile to a garage and it was gone when he got back?
Don't know what a rescue on a motorway would cost but you can't get a mate to help, bet you would be looking at around £200?
