Taking a rental bike could be a problem.

You want to cover 1600 km in three days? That's not impossible, but it's some pretty hard riding on a small bike, 7 or 8 hours a day. Then you'd have to turn around and come back.

You can get specific advice (especially about the border-crossing issue) at Golden Triangle Rider.

Rented bike can't cross borders, but if you buy one and have the ownership papers it should be ok. Main problem with your plan is time/distance. Presuming it will be a smallish 125cc bike it would be a real strain to make 500km/day. Then you have to turn around and do it all over again back to PP - exhausting! I've done some long distances small bike rides in Thailand and Laos and usually plan on doing at most 200-300km/day. If you get a bigger bike capable of higher average speed you'll still probably be riding all day every day. For a bike trip of this distance I'd prefer to have about 10-12 days. Last trip from Bangkok to Chiang Mai (home) took 2 very long days and we arrived late at night day-2. I would re-think.

Bad idea- a grueling trip assuming that NOTHING goes wrong (which it will).

Thank you everyone! sounds like i should not do it..unless i add on a bunch of days (which might actually be possible depending on my schedule). didnt realize papers were checked for bikes, etc.

appreciate the info all.

cheers!

Would probably take 7 or 8 hard days riding, then what if you hit bad weather? traffic cops? flat tyres? border problems? places to stay in remote areas? way too many issues. Much easier just fly to BKK then fly to CM, could probably do that in one day?

PS Did something similar recently on 125 scooter and covered 1,650km but took 16 days at a relaxed pace stopping off here and there for a day or two. Struggled on days were needed to cover 200km even. It aint an easy option!
