KIGALI, Rwanda — Game day. Sam Dargan, 29, a four-year veteran of the nascent sport known as moto-polo, awoke early — or relatively early, for a Saturday in East Africa — and began the traditional routine.

Fire up the stoves; let the chapati, banana and beans stew nicely. Wrap the mallet; duct tape works best. Check with your partner; be sure to arrive on time. Jon Stever, a teammate from Texas, is coming over with the truck and the pig to roast after the game. And do not forget the beer.

Motorcycle polo has only a few dozen dedicated practitioners here, but they are convinced the sport is destined for widespread popularity. Because who can resist an activity that combines single-cylinder engines, mallets and beer?

It is similar to traditional polo, except it was born out of this country’s distinctive palette of characters, customs and resources.
