It’s not unusual for companies to turn to custom motorcycles as way of promoting a product or even message.

But the motorcycle marketing tool that has helped so many custom bike builders through tough economic times and largely contributed to the television success of American Chopper took an interesting turn this week in Japan.

A custom motorcycle built by Japanese toilet manufacturer TOTO that reportedly runs on human waste will be unveiled today.

That’s right, if you can poop, you can ride.

Dubbed the Toilet Bike Neo Project, the campaign is part of the TOTO Green Challenge, the company’s stated goal of achieving 50% reductions in CO2 emissions in bathrooms by 2017 (vs 1990 levels).

This is no concept bike, the three-wheel motorcycle with a latrine is going on a month-long journey from Kyushu to Tokyo, making stops along the way to show off their new innovation and to educate people on the various green initiatives that TOTO is undertaking.

As we all know, no motorcycle is truly custom without some unique additions and the Toilet Bike is no different. According to reports, it features residual light imagery to write messages in the air as it rides by, play music and the toilet actually talks.

The true biker question would be which part would be chromed first?
