Comfort and Style: Super Headrest and Custom Seat


No seriously, give your head and neck a rest. Just because you're working hard, doesn't mean you have to be uncomfortable. The UTCustom Super headrest has a double hinge so you can place it just about anywhere you need it. So lean back and enjoy the ride.

Comfort Meets Function

We are pretty proud of this seat mesh. It started out as a remake of the muscle trikes we had a few years ago. Then we found an even more breathable material. then we triple reinforced the strapping. And finally we put a custom cargo bag on the back complete with insulated water bladder pouch!

More Wheel = More Comfort, More Clearance, More Speed

Let's talk wheel size. We jacked this trike up! The front wheels sit at 24 inches in diameter, with an option for a 26in back wheel. Why? Ground Clearance and Comfort. The bigger wheels raise the gearing and provides you with a smoother ride. It also increases your ground clearance making this trike great for more rugged terrain. As if you didn't have enough reasons to ride a KMX K90, then remember how much easier this trike is to enter and exit. This trike is awesome!
