Scooters are practical and all, but could one ever hold its own with sport bikes on a racetrack? In the latest harebrained CTXP adventure, Ari and Zack modify a 2009 Yamaha TMAX scooter to compete in a local race against Ninja 400s, KTM RC390s, and the rest of the small sport-bike kingdom.

As new dads, Ari and Zack are out to prove that putting children on motorcycles should be as normal and accepted as putting a baby on a bicycle or in a car. The guys have a series of tests, from the playground to the racetrack, to show their families and any other mother or father naysayers that motorbikes are the wave of the future.

If your motorcycle’s tires are the only thing anchoring you to the ground, wouldn’t an extra wheel make sense? Especially off road?! Zack and Ari aim to test that theory with a Can-Am Ryker Rally and Yamaha Niken that they’re pressing into service as “adventure trikes.” It’s six wheels, two dudes, and one big adventure in this episode of CTXP.

If you had to choose a vehicle to get across a city, what would you take? A bicycle? An electric scooter? What about a car, or a motorcycle? In this episode of CTXP, Ari and Zack test five ways to get across Los Angeles, and finally get to the bottom of commuting’s oldest question.
