Compare all - I am never loyal and I always end up with a better deal.
I'm with MCE fully comp and 15 months RAC cover included. 15 months for the price of 12 on the insurance too.
Leathers and helmet cover upto £1000.
I also paid an 'extra' £6 per month on the policy so that my excess is zero too.
It worked out £10 a month less than my previous insurer ( and I only had TPF & Theft cover with them !!!)

My policy is £28 per month with only 1 years no claims.

Shop around and be utterly ruthless - it's just a case of 'who's buying in the business this month'.
