Top photo tis indeed the 1155, south to north. The mid section is the best, below Phu Chee Fah.

This is not a fast sports bike road like the 1148, which has more sweepy bends and hard shoulders.
The 1155 is a slower road with tighter bends, no hard shoulders, but better surface than the 1093. I could ride it once a month for the next 5 years........ and may do as it's only an hour and a bit from home.
