The tarmac is the trip. This is what the road actually feels like under the tyres, state by state \u2014 the surfaces, the hazards and the one rule that will keep you upright. We hit rain, crosswinds, a 44\u00b0C desert and a switchback pass with no guardrails. Here is what we learned.
Mostly smooth, well-maintained two-lane. Some original concrete patches survive on the older alignments — ridged and noisy but rideable.
Sudden prairie rain (we hit it Day 1). Standing water on the flat alignments. Tar snakes on hot afternoons.
Check radar before leaving Chicago. The original-concrete sections are slick in the wet — ride them smooth, no sudden inputs.
Mixed — excellent on the scenic byways, patchy in places on the old alignments. Devil’s Elbow is narrow and shaded.
Deer at dawn and dusk on the Ozark back roads. Leaves in autumn. Tighter bends than anywhere so far.
Dial the speed back for the first real corners. High beam off for oncoming riders. The Devil’s Elbow bend is blind — hold your line.
Short and sweet — 13 miles of quiet, well-surfaced two-lane. The smoothest, emptiest stretch of the eastern route.
Almost none. Watch for farm machinery turning out of fields.
Enjoy it. It is the only Kansas mileage and it is genuinely lovely.
Oklahoma has more drivable original Route 66 pavement than any other state — concrete ribbons between Sapulpa and Hydro that are a time machine.
Spring tornadoes (April–June). Summer crosswinds. Tar snakes in 38°C heat. Long gaps between services on the western half.
In spring, monitor weather alerts daily and take shelter warnings literally. The original concrete is bumpy but grippy — relax into it.
Dead straight, dead flat, well-surfaced Panhandle tarmac. The longest, most relentless straights of the trip.
Relentless crosswinds that demand constant steering correction. Dust storms (haboobs) in summer. Heat mirage that distorts the horizon.
Relax the death-grip — constant correction is normal, not a problem. If a dust wall appears ahead, pull off and wait; they pass in an hour.
Long, quiet, well-surfaced desert roads. The pre-interstate alignment through mesa country is beautiful and largely empty.
Big distance between fuel. July–August monsoon thunderstorms build fast in the afternoons. Altitude gain to Santa Fe (7,200ft).
Fuel at every opportunity — we learned at half a tank the hard way. Ride early, rest after lunch in monsoon season. The bike may feel lean at altitude.
Varied and the best riding on the route — high-desert plateaus, ponderosa pine around Flagstaff, then the tight Sitgreaves Pass switchbacks to Oatman.
Sitgreaves Pass: narrow, no guardrails, RVs after 11am. Summer heat at the lower elevations (40°C+). Afternoon storms July–August.
Ride the pass at 8am — first and second gear, no rush, the whole pass to yourself. The pass is technical, not dangerous, if you ride within yourself.
The Mojave run (Kingman → Barstow) is long, straight and brutally hot on the National Trails Highway. The Angeles Crest detour into LA is the finest tarmac on the trip.
44°C+ in the Mojave in summer — the hardest day. Tar snakes go soft and greasy. LA traffic: six lanes, fast mergers.
Soak a cooling vest, start before dawn, finish by lunch in the Mojave. In LA, lane filtering is legal — use it sensibly and traffic becomes a non-issue. Take the Angeles Crest over the interstate.
The black crack-sealant strips go slick and greasy above 35°C. Brake and accelerate in a straight line, not over them. In the wet they are ice.
The Ozark and pass corners carry washout gravel after rain. Enter wide, look through, and do not commit to the apex until you can see it is clean.
The 1920s ribbed concrete in Oklahoma and Illinois is bumpy and noisy but grippy when dry. Relax your grip; fighting it tires you out.
Above 40°C the horizon shimmers and distance is impossible to judge. Slow for anything you cannot clearly identify — it is closer than it looks.
