help Please reccomedation?

My Harley ( Alright, take the piss, I've got broad shoulders and a pink
shirt! ) ) has been highly modified, including the wheels, these having
been changed to 18 inch jobbies instead of the normal 16's.
I'm ok with the back tyre as I can get the right size Avon Venom to suit,
but the front seems very narrow and I'd like to increase the width. It's
presently a Metzler 130/60 x18. Can somebody recommend a tyre that will be
wider but fit nicely. The rim can take a much wider tyre!!
Your help as always would be much appreciated.
TIA
