Hi Nial
I'm more North Derbyshire than Yorkshire Dales but I found this link a while ago, some nice links to routemaps and descriptors:
Check out some of the best drives in Yorkshire you can use while exploring our gorgeous county. Stick on your road trip album and enjoy.

Should be able to point you at some nice roads. You cant really go wrong tbh. North Yorkshire is Gods Own County as the locals will deservedly tell you.
Hawes is pretty much the centre of the dales - main street has several pubs full of bikers drinking cokes for their lunch. I think the Wensleydale Creamery is near here with free cheese tasting.
Malham is one of my favourite places on Earth, an hour or two's walk (depending which way you walk) to the Limestone Pvement.
Black Sheep Brewery in Masham for lunch (they do tours too) - it should be a crime to skip this. Lots of different red meats cooked in various ales - might need to skip breakfast that day.
Ripon isnt a bad town. Newby Hall has(d) a car show if your timing is right.
I quite like the James Herriot Museum (although its a little low key) in Thirsk.
Out to the coast, Bridlington and Scarborough are typical UK seaside towns, but I've always liked Whitby (if its the Goths Festival it will be rammed though). Pick up a fish & chips and some Whitby Jet.
And the roads between and around there are all pretty much great Zedding Roads.
You cant really go wrong - weather dependant - enjoy !
