Single-seat adventure from Maxxis

By the staff of Dirt Wheels


Maxxis Tire race support stalwart Mike Farmer has done a lot of racing and riding on two wheels, and he still owns dirt bikes. But as he says of his fairly recent passion, “I just can’t stay out of these UTVs!”

Even though the companies he offers event support for (CST as well as Maxxis) are powerful players in the UTV market, it was seeing neighbors in rural Utah having fun in UTVs that finally motivated him to step into a dealership. He is a family man, with everyone under the roof also smitten with wheels, so his first purchase was a Polaris XP 1000 four-seater. He soon found that he spent the majority of his time alone in the machine with many extra, but empty, seats.

This designated trail swapped between water, loose rocks, sand and solid rock slabs, and all could be within mere feet. The Maxxis RS1 is a weapon in these conditions.
Ryco builds the turn signal and horn kit and wiring. We are jealous of Utah allowing UTVs to transit between trail sections without trailering.


That realization prompted the addition of the 2019 Polaris RS1 single-seater to the family garage. Despite the fact that much of his youth centered on burning ever-faster laps around small tracks, living in southern Utah sparked a need for adventure.

“I still like riding motorcycles, but I have no desire to race them on a track any longer.” In a strange turn of events, his wife Amber motivated his first off-road races. Even though she eventually became a top-10 runner in the Women’s Motocross League National Motocross Series, her history is riding and racing off-road.

His off-road motorcycle experience (gained with Amber’s influence), and the sheer beauty and variety of southern Utah off-road riding, have shaped his current wheeled adventures.

The change from 6-ply 29-inch Maxxis Bighorns to 32-inch Maxxis Carnivores is a big one. These 8-ply tires are mounted on 15-inch rims.


We met up with Farmer near St. George, Utah,  so that he and Utah Off-Road Tours could show us some favorite trails while we examined his new single-seat adventure wagon. The time window we had available decreed that we have our driving adventures in 108-degree weather. All of our machines had roofs, and we were surprised at how pleasant the experience was despite the high temps.

Polaris obviously had short-course racing in mind when designing the RS1, but we have seen a large number of these machines in the dunes and on desert rides. For adventure driving the RS1 has a few limitations.

On the plus side, the car is comfortable, and it has more left-leg room than a four-seat RZR, and that counts for a driver as tall as Farmer. It is easy to see your wheel placement during technical driving, and the RS1 is supremely nimble. The downside is that cargo space is limited. Farmer wanted to boost the safety and the comfort of the RS1, but so far he fully trusts the basic performance and protection that Polaris designed.

Hunter Safety Products builds a comfortable seat and harness at reasonable prices. Even with this complex color palette, the retail is $404!


He does carry tools to repair tire punctures and to replace the CVT belt if needed. He has confidence in the 32-inch (29-inch is stock) Maxxis Carnivore tires, and they add to the ground clearance. The tires are tough and have an open tread pattern that works well in soft and hard dirt.

They come standard on Polaris’ latest high-performance RZR models. Just in case, he mounted the Carnivores on KMC XS234 Addict 2 Beadlock wheels so he can run flat in an emergency. To help the normally aspirated engine turn the larger tires, he mounted an Evolution Powersports Magnum slip-on exhaust system. The RS1 engine already had a major low-rpm response, but it is boosted by the exhaust. To make sure that he gets home, a compact 1.5-gallon Rotopax fuel can is mounted to the cage.

To prevent damage to the shock shafts, seals, and CV boots, Farmer installed the tough new Pro Series Coil Savers and CV Savers. Finally, he added a Rev Up graphics kit to the machine and topped it all off with a light bar from Tractor Supply mounted to the Polaris roof.

Much of this route consisted of large boulders. We were grateful for the added clearance and traction provided by the 32-inch Maxxis Carnivore tires. They grip in many conditions, and we had no flats.


Hunter Safety Products has seats that you can customize, and the brilliant color combo Farmer chose remains the standard $404. He chose convenient four-point harness seat belts from the same company that uses a normal seatbelt buckle.

He always tries to have his adventures in a group for safety, so a Rugged Radios radio allows car-to-car communications. He chose the 60-watt model to provide the most range for the radio. There was no need for an intercom with a single-seater! Utah allows UTVs to transit between trail sections on rural roads, but requires a horn and turn signals to obtain the required license plate. Ryco Motorsports has an affordable, well-regarded kit that Farmer employed.

For that rare pavement-pounding and trail safety, Assault side and center mirrors allow a clear rearview. We were impressed with the ease of backing up in tight conditions.

Even when we transitioned from water to rock slabs, the RS1 was sure-footed and ready for action. It was just as planted in faster terrain.Icia accus et volorep.


Despite the unseemly temperatures, we went on three completely different rides with Farmer and his RS1. We had pavement; fast, smooth dirt roads; mountainous rock roads; boulders; water crossings; silt; sand, dunes; and even slick rock. We even had some of that smooth clay that is unique to Utah and the surrounding states.

During our rides, the RS1 kept pace with a variety of other UTVs, including our Polaris RZR XP 4 Turbo S. It never had any trouble hanging, and when the going got tight and technical, the small machine looked like a ballet dancer cavorting with football linemen.

Any RS1 is somewhat rare enough to garner attention, but this striking Maxxis project was a people magnet wherever we drove it.

The basic suspension package from Walker Evans offers a comfortable ride with plenty of control for the rough and those sudden G-out impacts that spring up on remote trail adventures. Some of the mountainous rock trails had some daunting cambers, but they didn’t faze the RS1.

We knew that the competition-bred machine would be a weapon in the tight, but wondered about the high-speed manners. Farmer suggested that we stay in 4WD during all of our driving, and the RS1 responded with well-planted trail and dirt road manners.

The RS1 is a little light in the front for tricky climbs, but we encountered nothing that stopped or even startled us.


We could really see the value of the shorter wheelbase when we skirted a million rocks while dealing with multiple river crossings. It is very nimble, wheel placement is easy and the taller tires give it all the clearance required.

Our helmets were not wired for the radio, and after driving without it, we can see that it is almost a requirement in the RS1. Through it all the RS1 was comfortable with all of the engine performance and ground clearance we needed.

No doubt there are suspension mods and some undercarriage protection in the works in the future. For now, though, Farmer has personalized the car for his geographic requirements and to suit his passion.

It is easy to mess up the best part of a machine’s performance by adding too much weight to it, but Farmer carefully considered the weight and the cost of the mods before he made them. The result is a single-seater that is a highly desirable adventure mount.
