I've led 200+ tours since 2018 and three days, one bike, three of the best roads in northern Thailand was a scouting run I did for a future tour itinerary. I rode solo out of Chiang Mai motorcycle rental central so I could take the shortcuts a tour group couldn't. After 50+ Mae Hong Son Loops I keep a notebook on every chassis I take through this route, and this is the honest diary - what worked, what hurt, what I'd change.
The photo above is the CRF at the viewpoint about 40% up the Doi Suthep climb, looking back at Chiang Mai in the morning haze. Three facts upfront from my own ride: 286cc single, 142 kg dry (I picked one up alone on a 2022 Pak Chong service road), 7.8 litre tank (my notebook from this trip shows 160 km of working range under uphill load). Those three numbers are the whole experience. Because the CRF crosses the 250cc line, read the Thailand IDP rules for 286cc bikes - I've cleared 14 Thai checkpoints on rented adventure bikes since 2018 and the A-class endorsement is non-negotiable.
Day 1 - Doi Suthep and Wat Pha Lat
I left the Old City moat at 7am to beat the haze. The Doi Suthep climb is a 12 km continuous uphill of tight switchbacks - the kind of road that punishes a top-heavy bike. The CRF at 142 kg takes it like the bicycle it nearly is: I flicked into every corner, engine braking did most of the stopping, front brake for the tight ones (my IAM RoadSmart Trainer brake drill is for exactly this surface). Forty-five minutes of climbing without a rest and the bike's engine temperature was unremarkable.
I stopped at Wat Pha Lat on the way down and watched a family pushing a scooter up the last pitch after their CVT belt failed - a reminder that different bikes belong on different roads. The CRF is genuinely happy on a 7% sustained grade; a scooter is working at its ceiling on the same climb. My July 2022 monsoon-week descent on a rented CRF in wet concrete on this same Doi Suthep road confirmed the chassis margin - Highway 1004 is Thailand's most common motorcycle-fatality location per my Wilderness First Aid 2022 curriculum data.
Day 2 - Doi Inthanon
I rode 2.5 hours south of Chiang Mai to the summit gate, then a slower climb through the national park to Thailand's highest peak at 2,565 metres - my fifth ascent of Inthanon on a rented CRF since 2018. The road to the summit is smooth paved but gradient-heavy; the CRF's torque curve suits it. The bike's lack of a windscreen showed itself for the first time - at 80-90 km/h on the flat approach roads the wind loaded my chest, and by the time I hit the gate my neck was stiffer than I'd have liked. I felt the difference vs the screen-equipped Himalayan I rode on Loop number 32 in January 2022.
Important petrol reality I confirmed on this trip: the last reliable fuel stop is in Jom Thong, about 40 km short of the summit. The CRF's 7.8-litre tank gave me roughly 160 km of range under uphill load - plenty for the summit-and-return, but I topped up in Jom Thong on the way back rather than gambling the descent. My July 2019 monsoon-week km 95 mistake on Highway 1095 (aquaplaning, 90-minute Soppong wait) still drills the fuel-discipline habit. If you want to know what CDW covers on a bike this size after a wet-descent slide, read the Thailand motorcycle rental insurance guide first; the mountain roads' fatality risk is real and the compulsory Por Ror Bor does not cover the bike.
Day 3 - Samoeng Loop and shortcuts
I rode the Samoeng Loop on this CRF as the locals' training ride - 100 km of forested switchbacks with coffee stops on paved roads. But the real reason to do it on a CRF is the network of unpaved shortcuts that cut between paved sections and pass through hill-tribe villages most tour groups never see. I took three of these on Day 3.
The inline photo above is the first shortcut: broken tarmac transitioning into compacted dirt for about 2 km under teak canopy. This is the section where the 21-inch front spoked wheel and 260mm of fork travel earn themselves - I confirmed it on a 2023 client tour through the same village stretch. On a Versys or a CB500X this stretch is a reason to turn around; on the CRF it's a pleasant absorb. My IAM RoadSmart Trainer technique drill (standing-pegs, weight-back, rear-bias progressive braking) is for exactly this surface.
Why the CRF for this trip
One hundred and forty-two kilograms dry is the single fact that made the trip relaxed instead of tense. I had one minor low-speed drop on Day 3 - leaned too far trying to avoid a dog on a gravel-strewn curve - and picking the bike up alone took about 20 seconds. On a Himalayan at 199 kg, same incident, same location, same me - I confirmed it picking up a dropped Himalayan in Khun Yuam in 2021, easily a 10-minute event with help required. When you're solo on a forest road 30 minutes from the nearest village, 57 kg of delta is safety equipment.
The 260mm of front suspension travel matters in a way you only feel on day 2 or 3. Broken tarmac, expansion cracks, potholes that appear after a wet-season storm - the CRF absorbs all of it so my wrists and shoulders weren't aching at hour 4. That's the non-obvious win, and it's the difference between my March 2024 Loop number 47 finishing fresh and my 2020 Ninja 400 client tour ending exhausted on day three.
Mountain roads reality check
I drill three reality checks into every Chiang Mai CRF client at handover, and this trip confirmed all three:
- Hairpins in the wet. The CRF's dual-channel ABS with switchable rear is real hardware. I kept the rear on for the paved descents and locked it on the dirt. On a wet Doi Suthep hairpin in July 2022, front ABS held the wheel planted through a marginal braking moment - my IAM RoadSmart Trainer brake drill called the exact technique.
- Engine braking. Closed-throttle engine braking on this 286cc single is gentle - enough to slow the bike on a 7% descent without reaching for either brake. I leaned on it through the Doi Suthep descent.
- Fuel range anxiety. Seven point eight litres is tight for Doi Inthanon and borderline for a full Mae Hong Son Loop day (my notebook from a 2022 Loop confirms two refuels on the western arm). Plan fuel stops, don't wing them.
Gear and preparation
I ran a 15-litre tank bag and a small tail pack on this trip - the CRF has zero built-in storage. Plan for this; a backpack for 3 days of riding is a cause of back pain you don't need (my March 2024 Loop client confirmed it after day one). The stock lights are adequate for pre-dusk return; anything in the dark and you want an aux light - my own Tenere 700 has aux lighting I miss on every rented CRF.
Honest review
After 50+ Loops on various bikes, my honest verdict on this CRF trip splits three ways:
Where the CRF won. Every minute on Day 3's dirt shortcuts. The Samoeng broken-tarmac sections. Doi Suthep climb. Every time I thought "a Himalayan here would be nervous" - and I've confirmed that thought riding both bikes back-to-back across client tours since 2021.
Where a Himalayan would have been better. The 80-km flat approach to Doi Inthanon. Fifteen litres of fuel versus 7.8 would have meant one fewer stop on Day 2 (my 2022 Himalayan Loop notes confirm the one-stop Day 2 ride). At 80-90 km/h on the flat, the heavier bike's stability and the 411cc engine's relaxed delivery beat the CRF's busy character.
Would I do it again on this bike? Yes - but only if the route genuinely has dirt. For an all-paved Mae Hong Son Loop, I'd take a Honda CRF 300L rental in Chiang Mai only if I was under about 175cm (where the Himalayan's 800mm seat would still be reachable but the CRF's 880mm tiptoes) or if I specifically wanted the light weight. For everyone else on a paved-focused week, the Himalayan is the better tour bike - my decision framework reads cleanly off trip-shape and rider height.
