Not just praise for the roads and stunning scenery. But if you need somewhere to stay, I can recommend the biker-friendly Bracarina House (a B&B at Invermoriston):

We’ve stayed there twice now, 2 years in a row. It’s a fair old slog but if you’re going that far, Invermoriston makes a perfect base. No touring around for us - we droped all our stuff and returned to base at the end of the day. The West coast, John O’Groats and Aberdeen are all within reach of a day’s return trip. There’s a nice bit of concrete on the drive to rest your bike on and it’s right on the A82. A stone’s throw from fantastic roads up to Inverness and The Kyle of Lochalsh. Block bookings are the best bet - hikers from Glasgow to Inverness up the Lochs tend to nibble away at bookings 1 day at a time.
I can’t sing praise highly enough, the least I can do is pop in a good word here.
