Hi aws
Most of the roads up there are great.
A favourite of mine is just north of Fort William heading toward Kyle of Lochalsh,very fast sweeping bends
The road into FT from Glencoe is great too,though normally has a lot of traffic with limited visibility and overtaking spots.
Theres an amazing little road running to Newtonmore which just seems to be miles of twisty chicanes,however this has the reputation of being quite dangerous as you cant see around the bends and the road is very narrow.
The classic run to Inverness along the north side of Loch ness is a good'un.
i could go on and on......
Oh, while your there you have got to try a trip to Oban then onto lochgoilhead,turn around and then do it on the way back.
These are all fantastic bike roads and we are surely blessed,however,it has rained here for seven solid months so you'll have to trust to luck on that one.
i'm sure you'll get a couple of the guys to join you though I think I'm going to the Northwest 200 that weekend.
Enjoy!
remind us nearer the 18th and I'll see if I can make it along to watch at Knockhill.
