Don't think twice, these guys are pro in all aspects, this is the best attraction in the island!
I booked the 8hr tour, round trip Ubud to Mt. Batur with a 150cc Kawi, and I can't complain. The tour was perfect!
It was low season, so I found myself alone, which made me worry at first,... but boy this was worthy! In the end I actually felt on a private lesson with my guide Dex, who is a pro rally/enduro rider and certified coach.
I have experience riding larger bikes on asphalt, but the tour/class with Dex is something I am taking forever with me, and hopefully will evolve into a new hobby off road.
I started my first hour all stiff and lost on dirt, but little by little he dropped some vital techniques, one at a time, adapting my skills to every new challenge proposed. By mount Batur I was already flying on deep sand, dirt, rocks, ridges... confident enough to have way more fun than I could imagine!
I started with rice paddies (learned proper posture on this type of bike), later some jungle (learned flat turns), soon a bamboo forest (momentum x obstacles), went down a dry river bed (learned to ride on scary deep soft sand), went up the valley (learned hill climb). By the time we reached the black lava, I used all learned on a unique terrain that looks like another planet. On the way back we went through single tracks through the rain forest, and that was hyper cool, sliding and rushing between trees, confident on the bike and on myself.
But don't get me wrong, the tour is not all about dirt bike experience... you are signing up for an adventure! You will meet several locals and chat with them, you will see a beautiful side of Bali where you won't find other tourists. And these guys are pro, they will adapt according to your needs, skills and preferences. I tailored the tour to my liking. Dont be afraid to try the same, give them a call if you are in doubt or have any special requests/preferences. After all, they are all about the adventure!
Un grande abrazo a Allan, Dex y a todo el equipo! If I'm lucky enough to visit Bali again, I'm surely dropping by their shop for another tour.
