Bennetts gave me the best quote - I used to have three years NCB but lost it as haven't been riding for two years (and car NCB not transferable
)
Norwich Union and Eagle Star can be good - but it depends on what bike you are insuring and whether you have good security.
Mine is £72 TPFT for a 97 M600 with aftermarket cans. £200 excess. Parked on driveway. Datatagged.
