unfazed, i'd be keen on those kerry/cork routes if you can post them up. i'll be heading from fishguard.
There you are, follow the letters A to X, they not only give some great routes but also the direction which give the best views even the route back to Rosslare is a great run and has a nice bit of scenery also.
It includes a few of the must see places like the most scenic route to Kinsale, the Old Head of Kinsale, coast road to Clonakilty, the very enjoyable main road to Skibereen the road to Ballydehob, Mizen Head, Bantry, Glengarrif, Castletownbere, Beara Penisula, Back to across the Healy Pass (south to North) then Kenmare and back accross the Caha Mountain Pass to Glengarrif, then cross the Borlan Valley and into Killarney and up to Moll Gap and back to Kenmare and most of the Ring of Kerry and on to the ride through the famous Gap of Dungloe and back to Molls Gap back to Killarney, Miltown, Castlemaine and all the way to Dingle circle Slea Head and back to Dingle to ride the Connor Pass, then Tralee, Castleisland, Mallow Fermoy, Lismore, Dungarvan and back to Rosslare.
Many of the routes here are missed by tourist. If you like these there are many mome more I can add. Give yourself at least 5days to have the most fun and mind the sheep in places.
http://goo.gl/maps/4KUYVThe route through the Gap of Dungloe may not be for the faint hearted, but well worth the effort, but if you are well used to riding in all types of roads and conditions, then you will have no problem. I have been on all these roads on my the 600 and 1000 Fazers two up and any of the Fazers are more than capable of doing even the 400. You can always call to my house near Cork Airport for a cup of coffe/tea and a chat including a few suggestion of where to eat and sleep along the way.
