I love this short section with some nice corners. Be carefull - on some corners you can meet some speeding cars in front of you in your lane.
Kuldīga is one of oldest cities in Latvia - take your time to see oldtown, bridge over river Venta, you can have a good dinner in Kuldīga old town.
Road Kuldīga - Kabile - Zemīte is freshly reconstructed, on summer 2015 some short sections was still on reconstruction, now you can enjoy perfect asphalt, and may be some kmph extra ;)
Tukums - Klapkalnciems is very spectacular road, unfortunately it hasn't been reconstructed some 20-30 years, but it is still in quite good condition, and corners are just amazing!
From Klapkalnciems you can go to see Riga or Kolka, then Ventspils, both directions have reconstructed pavement.
