How Many Bikes Are Too Many ?

As we can all agree that a new bike is always nice to have but is it possible with all the bikes Triumph have released over the last year or so that it's getting very much like a kid in a sweet shop so many good bikes but a lot of the same type to do the same job the new viper 400 is very nice though and now it has moved me away from fancying a new BSA Bantam for a convenient jump on and go in all weathers
