This is a good circular route, with plenty of variation to give you a great ride regardless of your personal favourite aspect of motorcycling.
There is some traffic during the weekends, but this route has a number of stops for hot drinks and views.
The corners are mostly flowing, with only a few hairpins, just before you get to Ruthin. At Denbigh, there is a bike shop with a cafe if you want to stop. The Denbigh to Mold A541 has a few quarries on it so there can be a large number of big lorries who know the road very well, and drive it confidently. They can be difficult to overtake. However, there are a couple of long straights where this is possible safely.
It should take around an hour or so at sensible speeds to do the whole route
