Funny thing about insurance is that the 'best' keeps on changing. Several years ago we'd have been singing the praises of Carole Nash Insurance who were offering absolutely unbeatable deals for motorcycle riders, especially riders of classic bikes. And to be fair, if you are a classic bike enthusiast they're probably very much still worth a call.
If you're looking to insure anew (or second hand) SINNIS then we can recommend MCE who seem to offer the best value for most of our customers.
The rest of you will probably want to try out Rampdale who are an independent brokers of motorcycle insurance...
Finally, it's also worth giving Lexham a try and see what they can do for you. Follow the link below.
