Having riden just about every road within three hours of Perth in the last three years I venture a motorcycle road rating system for reporting rides:
Platinum ...brilliant motorcycle road with hills sweeping bends, scenery, good surface, reasonable speed limit and limited traffic with a readily accessible Bakery or good Cafe
Roads Nanga Road
Chittering Valley
Bridgetown to Nannup
Caves Road
Gold ... almost Platinum but let down in one or more criteria
Roads Mundaring Weir
Balingup Nannup
Bindoon Mogumber
Dwellingup Quindanning
Mornington Mills Road
North Spur Road
Ferguson Valley Road
Kirup Nannup
Silver .... a good ride, good bends but with lenghty straight bits, possibly a poor surface, or too slow a speed limit
Roads Nettleton Road
Julimar Road
Toodyay Road
Clackline - Toodyay
O'Brian/Berry Road
Kingsbury Drive
Del Park Road
Lakes - York Road
Mogumber- New Norcia
Capel - Donnybrook
Bailup Road
Canning Dam-Araluen
Bronze OK but a bit boring
Roads Great Eastern Highway
Pearce- Bindoon
South West Highway
Albany Highway
Base Metal Only good to get you to and from a good motorcycle road
Forrest Highway
