HCR Racing has worked with Dave Cole of Ultra4 King of the Hammers (KOH) fame to promote the KOH UTV race over the past seven years. The February 4th, 2016, KOH UTV race will have a new twist—a Class 4900, limited-edition spec car from HCR Racing, complete with KOH race entry fee, tech package and $10,000 in additional contingency purse money from HCR Racing. This turnkey King of the Hammers Limited Edition racer starts out as a Polaris RZR XP 1000 EPS and gets the HCR Racing long-travel suspension kit with boxed arms and King Racing Internal Bypass shocks, plus a complete upgrade for safety, strength, comfort and communications, all to take on the toughest UTV race in America.
WHAT’S NEW FOR KOH 2016?
CNC-cut, boxed suspension arms extend the wheelbase 3 inches and increase width by 8 inches to supply over 21 inches of wheel travel with the HCR Racing LTS kit. King Racing IBP shocks with dual-rate springs supply the plush ride. The HCR complete LTS kit also includes frame gussets, a new front shock tower for proper geometry, FK 5/8-18 heims and chromoly construction, Summers Bros. +4-inch 4340 axle bars, spherical front spindle setup, and high-link or grade-9 race links. HCR Racing fender flares are steel DOM tubes with integrated rocker assemblies that increase strength, durability and roost protection. An SDRcustom, KOH race-legal, six-point cage with integral rear bumper also beefs up the OEM frame, and the roof is 1/8 inch aluminum. American Rock Rods H-D tie-rods have OEM-style inner joints, machined aluminum rods with a central hex for toe adjustments, and an aluminum QA1 heim with an 8600 pound radial/static load rating.
SDR full doors open but lock for race legality, and the PRP nets meet KOH rules. PRP Custom GT race seats have exclusive embroidery and race numbers, and PRP five-point harnesses are standard. The cab features a PCI 50-watt race package with Kenwood TK-7360 50-watt radio, co-axial, antenna, and radio and intercom brackets. The cab also sports an Axia billet rear-view mirror, a 2.5-pound fire extinguisher with billet mount, and metal seat bases that lower the seat height 1–1.5 inches. There’s also a Lowrance Elite 5m Baja HD GPS system with a custom XP1K Elite 5 GPS bracket. For tech, there’s a 9x9x4-inch first-aid kit, amber light, horn and reflectors, and the Warn Provantage 4500 winch has 55 feet of 7/32-inch rope with the fairlead protruding through an SDR bumper and skid plate. A Vision X 30-inch, low-profile LED light bar rides on top with integrated thermal protection and 5-watt LEDs producing 528 raw lumens each. A PURE Polaris 3/8-inch molded HMW skid plate arms the KOH LE undercarriage.
Method Race Wheels’ 401 fourteeninch beadlock wheels have 6061 aluminum beadlock rings, grade-8 zincplated mounting hardware and a 1600pound load rating. They come in matte black or a machined finish, and they clamp Tensor Regulator 30x10R14 tires with eight-ply construction. A fifth wheel rides vertically in the XP1K bed with a steel mount. The HCR Racing KOH LE has a custom wrap that’s numbered for KOH.
HOW DOES COST COMPARE?
The standard RZR XP1K EPS is $20,299, while the Fox Edition is $22,999. The High Lifter Edition is $23,499, and the Desert Edition is $27,999. The HCR Racing KOH Limited Edition XP 1000 is $45,199, and the KOH race-ready platform kit is $24,900.
HOW FAST IS THE PROSTAR 1000?
It’s as quick as the stock RZR XP 1000, and CVT clutching is revised for the 30-inch Tensor tires and extra weight of the KOH LE. The 110-horsepower ProStar engine is left stock for durability, and it’s plenty fast for the desert sections of the King of the Hammers. The HCR Racing LTS kit and IBP King shocks allow it to attain and maintain much higher speeds in deep desert whoops too.
WHAT ABOUT THE CVT/AWD DELIVERY?
It’s also excellent, like stock. The 2015 CVT cover has a third duct for extra cooling capacity for the new CVT belt, and CVT engagement is smooth yet quick. Stronger Summers Bros. axles offset the stresses of the larger Regulator tires and extra suspension travel. The standard Polaris AWD system only engages the front differential when it senses the rear tires spinning, (so it doesn’t push like alltime 4WDs going into turns, but it only supplies rear-wheel braking on steep descents).
HOW AGILE IS THE KOH LE’S HANDLING?
It’s not as agile as the Shock Therapy Fox Edition RZR XP1K featured in this issue. Long-travel suspension arms are 4 inches wider per side, so the KOH LE can maintain high cornering speeds without bicycling, but it doesn’t have the planted, connected feel of the Fox Edition’s two torsion-bar setup.
HOW ABOUT THE HIGH-END HCR SUSPENSION?
It’s incredible. Total travel is in league with Trophy Trucks, and the boxed arms with internal honeycombing are super strong. King Racing IBP 2.0 front and 2.5 rear shocks have custom valving and spring rates dialed for the LTS kit, so the KOH LE gobbles desert terrain like no other UTV. More than 21 inches of travel allows the KOH LE to ride like a magic carpet, and the finned rear reservoirs have extra cooling capacity.
HOW STRONG ARE THE BRAKES?
Strong like a bull. The OEM RZR XP 1000 brakes have 220mm rotors squeezed by two-puck hydraulic calipers at all four corners. The HCR Racing LTS kit supplies longer stainless steel brake lines, and the 30-inch Tensors provide plenty of braking bite.
WHERE IS THE HCR KOH LE XP1K HAPPIEST?
Conquering gnarly desert terrain. Whether it’s crawling along at deserttortoise pace in huge boulders, snaking through sand washes or floating over 3-foot sand whoops, the HCR Racing KOH LE provides a comfortable ride with all systems needed to navigate and communicate at speed. Sync a couple of bumper-mounted GoPros to your iPhone for digital spotting, and get ready to collect $10,000 in HCR contingencies and a free RZR XP 1000 from Polaris.
WHAT ABOUT TRAIL COMFORT?
It’s off the chain. The new roomier cabin, lower sitting position, and custom PRP GT seats and harnesses are super comfortable and provide
confidence at speed. The roof, doors, nets and intercom are all top-notch, as is the GPS system with its large, easyto-read screen. However, it’s the plush ride of the HCR Racing LTS kit and King Racing IBP shocks that’s most impressive.
WHAT’S OUR FINAL ANSWER?
UTVs are super popular because they provide a ton of performance at a relatively low price when compared to Trophy Trucks, sand rails and top-class buggies. Many enthusiasts build their UTVs piece by piece and end up with a full-featured machine like this one. HCR Racing does the building, testing and tuning, so the KOH Limited Edition RZR XP 1000 has a lot of development behind that shocking price tag. Wide Open Adventures charges $35,000 for a SCORE Baja 500 or 1000 Class 10 race package, and you don’t get to keep the buggy. So $45,000 for a KOH UTV-racing experience and fully loaded RZR XP1K is a bargain, especially if you beat Mitch Guthrie and win $30,000 ($10,000 HCR bucks, plus a $20,000 RZR), plus the regular King of the Hammers UTV purse.
