The only thing I'll say about Southern Ireland is that its incredibly bumpy!!!!!!!
I mean incredibly!
I used to havea BMW 1150 GS and ithe bumps caused the front indicators to come loose and literaly hang by their wires!!!
I'd tighten them up and 10 miles later the same again!!
My brother inlaw was on a Blackbird and he found numerous loose nuts and bolts daily!
Your shock will get a good work out thats for sure!
I recommend you use someone elses bike!
Irelands great though........apart from the roads, mind you the odd piece of European funded tarmac is nice even if it only lasts for 500 yards!!!!
Good Luck.
