Polaris, Can-Am & Kawasaki specialists in Washington UT — minutes from Sand Hollow, serving St George, Hurricane & Ivins.
MST Motorsports services UTVs, side-by-sides (SXS), and powersports vehicles — Polaris, Can-Am & Kawasaki specialists; we also take on Honda and Yamaha work, call ahead and we'll confirm the fit. We provide complete diagnostics, repair, and service at our Washington, UT shop, and our technicians understand the specific mechanical demands these platforms face in Southern Utah terrain.
Many of the machines we service are used regularly at Sand Hollow State Park, where red sand dunes on Sand Mountain, technical slickrock, rock crawling terrain, and desert trails put extreme stress on clutches, belts, shocks, cooling systems, and drivetrains. We approach every powersports repair with the goal of keeping these machines reliable for the conditions they actually operate in. Turnaround measured in days, not weeks — and you'll get a timeline before we start.
While your UTV is here for suspension, clutch tuning, or accessory work, the same shop handles complete repair and maintenance. We do belt and hose service and preventive maintenance on recreational machines and work vehicles alike, from weekend dune runners to dedicated ranch builds. You never need two shops — MST covers it bumper to bumper.

Modern side-by-sides are complex machines with electronic fuel injection, power steering, multiple drive modes, and sophisticated suspension systems. When something goes wrong — whether it's a check engine light, a power loss, an unusual noise, or a handling change — proper diagnostics are essential.
For Polaris and Can-Am we run OEM factory scan tools — the same diagnostic access the dealer has on those platforms. That means live ECU data, calibration and service routines, and fault information that generic OBD scanners cannot see on a side-by-side. On other platforms we use professional powersports scan equipment plus hands-on inspection. See our equipment & facility for details.
Our repair and service work covers engine diagnostics, drivetrain repair, axle and CV joint service, cooling system maintenance, brake service, and steering diagnostics. We work on trail machines, dune runners, work-side-by-sides, and everything in between.
The CVT clutch system is one of the hardest-working components on any side-by-side, and it's one of the most common failure points we see — especially on machines that ride Sand Hollow regularly. Sand riding puts sustained high-RPM load on the primary and secondary clutches, generating heat that degrades belts and accelerates wear.
We perform complete clutch repair, service, and CVT tuning — including clutch weight adjustments, spring rate changes, helix angle setup, belt replacement, and deflection checks. We tune clutch setups based on your specific machine, tire size, elevation, and the type of riding you do. For Sand Hollow riders, that typically means a setup optimized for cooler belt temperatures under sustained dune load.
We perform in-house shock repair, rebuild, and service for Fox, King, Elka, Walker Evans, and other major brands. A full rebuild includes seal replacement, fresh shock oil, internal component inspection, and re-valving when needed. Desert sand and dust accelerate seal wear and contaminate shock oil faster than most owners realize.
Beyond shock work, our suspension diagnostics and service covers A-arm inspection and replacement, radius rod condition, bearing play, tie rod and ball joint replacement, and alignment correction. For machines that see regular Sand Hollow use, we recommend shock service every 40–60 hours and suspension component inspection at the same interval.
Electrical problems are among the trickiest issues to diagnose on modern powersports machines. Fine desert dust works its way into connectors, sensor harnesses, and control modules — causing intermittent faults, limp modes, and no-start conditions that are difficult to track down without proper diagnostic equipment.
Our technicians perform complete electrical diagnostics, wiring repair, and accessory installation across all major powersports platforms. We also handle accessory wiring for lights, winches, communication systems, and aftermarket electronics — done correctly to avoid the ground faults and overloaded circuits we regularly see from improper installations.
From roll cage installs to forced-induction upgrades, we handle the reliability and performance work that keeps your machine safe and strong — see our full turbo & supercharger service for forced induction details.
Sand Hollow State Park draws riders from across the United States and internationally — and for good reason. The mix of deep sand dunes on Sand Mountain, technical slickrock, rock crawling terrain, desert trails, and access to the Sand Hollow Reservoir and surrounding Warner Valley trail systems makes it one of the premier off-road destinations in the country.
That terrain demands machines that are properly set up and maintained. Clutch cooling and tuning for sustained sand load, shock service for high-speed desert washboard, suspension setup for rocky trails, drivetrain reliability for technical terrain, and preventative maintenance to catch problems before they leave you stranded — that's what our Sand Hollow pre-ride service is built around. UTV owners should also follow the platform-specific manufacturer maintenance schedule — hours matter more than miles on these machines.
MST Motorsports is a family-owned and operated shop with deep roots in the Southern Utah off-road community. We ride the same trails, know the same terrain, and understand what these machines need to stay reliable in conditions that factory service manuals don't always account for.
Our approach is straightforward: honest diagnostics, quality repair, and fair pricing. We don't upsell work that isn't needed, and we don't cut corners on work that is. When your machine leaves our shop, it's ready for Sand Hollow, ready for the desert, and ready for whatever you throw at it.
Diagnostics, clutch repair, a shock rebuild, electrical work, or a pre-ride check before the weekend — bring your machine by or call and we'll figure out what it needs. Serving Washington, St George, Hurricane, and the Sand Hollow area.
