Throttle Out

Zack Courts and Ari Henning are back on two wheels, with the boys attempting a 1,200-mile road trip down the Baja Peninsula.

Zack and Ari try to answer the question of which bike you should grab for the end of the world. With the zombies closing in, they might even want to build their own.

Every motorcyclist loves the sound, smell and charm of a two-stroke, but these days they're all but extinct. Ari and Zack tackle the issue by trying to mount a 1987 Yamaha Banshee four-wheeler engine into a modern YZF-R3 chassis.

Zack and Ari want to see what's faster, a car or a motorcycle. They figure they could probably drive a fancy car around a track just as quickly as they could ride a bike.

Zack and Ari wussed out on winter a decade ago by moving to California, but for lots of people, winter is a very real thing.

Zack and Ari think it's a shame that you can only enjoy riding a motorcycle with one other person. They aim to solve that problem by creating a two-wheeler capable of carrying the entire family.
