Sure does look different flying down the "wrong" side of the road. The co-pilot and I are planning to do this in September 2017. Talked to the rep for this self-guided tour rental outfit at the local MC show a couple of weeks ago and we became very interested.
M.H. - is this something similar to what you did a while back? I saw the videos you posted.
Chippy...any comments or recommendations would be appreciated (time of year, rental outfit, etc). Thanks for posting this.

It's held during the June Bank Holiday weekend in Killarney, Co Kerry. About 3hrs (180 miles) from Celtic Bike Hire in Kill, Co Kildare.
From Killarney, you will have access to the Wild Atlantic Way, Ring of Kerry, Slea Head and the Dingle Peninsula. You could even take in the Cliffs of Moher and The Burren, about 80 miles north of Killarney.
All this is on the west coast.
The east coast has some spots too. Glendalough and the Dublin/Wicklow hills. The run from Dublin to Wexford is good (albeit mostly dual carriageway now). Mount Leinster is a nice spot on a good day.
Dublin itself has many attractions, but you'd really want to lock the bike up good and proper when parking (same as any big city).
I guess it all depends on how long the visit is, where you will be based (if at all), and what interests you have.
As for the time of year; summer is best as always, but never guaranteed to be dry. Avoid holiday times if possible, unless you want to head to the BikeFest.
I think MH did it last year, and will surely have tips regarding the visitor view.
Check online for anything that interests you, and either myself or another Irish member, of which there are a couple on this forum, can try to give you our perspective.
