What it is
Khun Yuam east to Mae Chaem. The shortcut that halves the loop, and the hardest riding in this network.
The long version
Inference — the OpenStreetMap trace of this road comes back incomplete: 38.1 kilometres of it stitched, against the roughly 64 the road runs. Over the part that is mapped it carries 159 curves at a 25-degree threshold with 25 hairpins — 4.25 a kilometre, denser than Route 1095's 5.71 — on a third of 1095's length, with a fraction of the traffic. The rest of the road is not on this disk; treat the total as a floor.
What the numbers do not carry is the character: no town in between, long stretches with no fuel and no phone signal, gradients steeper than anything on 1095, and sections where the seal has broken up. It is the most rewarding road here and the one with the least margin.
Inference — in the rains it comes off most plans. Steep, broken seal, and nobody coming past for a while is a combination that stops being fun when it is also wet.
