I'm no BB expert.. I have visited a couple times on KTM 450exc, 500xcw, and 300xcw.
random thoughts:
1. There is no "right" bike for BB, I think you can have a blast on little bikes or big bikes
2. The distances, challenges, and logistics are what make the wild west FUN
3. On my small bikes, I carried around 3.5 gallons
4. I usually bring 2 wheelsets. One with dez tires, the second set are DOT
Dunlop 606's. Def bring a DOT legal bike, valid drivers license, and proof of insurance
5. I enjoyed my 300 two stroke out there. I rode the state ranch and the
national park. I carried oil in small shampoo bottles. Loved the tighter
sections and of course hated long pavement runs
6. Food: Awesome food everywhere!
7. Temps: Anything from 30 at night to 95 during the day.
Embrace the unknown. Viva Terlingua!!
8. Vibration: Its not the displacement that would point me towards a
machine, its the vibes. Do you want to ride 8 hours on a paint shaker?
I am a 2 stroke fan... but if I had a ktm 350 and a ktm 300 in the shed,
I would probably take the 350 to the national park and the 300 to the state ranch
9. Fuel: local stuff is low octane. Some stations close at 5pm
Last trip Panther Junction was open 24 hrs (but canopy lights were off) and Rio
Grande Village closed at 5pm. Running out of fuel anywhere out
there ranks pretty high on the suck-meter
10. Medical: Its far to a ranger. Its far to a hospital. Ride smart
11. If you're sitting on the fence, then you should go! Its remote, desolate, and
beautiful. Unspoiled.
