Recently picked up a nicely modified KLX and am having a blast learning how to ride it.
So far I know of two off road riding areas in Bangkok and I've heard there are some more.
First is "Bo Din" an abandoned quarry just to the northeast of Minburi and just south of Lam Kuk Ka-
I discovered this are when Kawasaki sponsored a Versys offroad clinic there last year:
Here's a Google Maps Link:
Decimal GPS: 13.886782,100.796598
Lat 13° 53' 12.4152" Long 100° 47' 47.7528"
Bo Din is where Kawasaki, BMW and clubs such as Stormriders and SiamEnduroClub hold riding courses and races- it's a HUGE area and people are always out there building tracks and jumps and obstacles.
There's an awesome floating restaurant on the reservoir too that serves excellent food and ice cold beers.
Messing about on the KLX:
This sure beats going to the gym! (Not that I ever go to the gym) I plan to try and hit this place at least once or twice a week. Brilliant fun and what a workout!
I plan to hit Bo Din again this Sunday afternoon around ~2-3pm with one or two other KLX riders and there's also a big group of Thai guys who go there pretty much every Sunday. They mostly ride trials bikes and are a really friendly bunch.
All are welcome! Hope to see you there!
