this is one of the unique means of transportation in the Philippines, we call it locally as “habal-habal”. it is a regular 100-120cc motorcycle modified to seat as many passengers as possible. This is the only picture i caught personally with the most number (only 5 😦 ). i used to see more passengers than this, by far up to eight, but have not captured them on camera.
this mode of transportation is regularly utilized for transport at difficult mountainous, and uneven terrain that only a motorcycle can easily access, at a least amount of cost.
