RZR XP 900 FORCE REDUX

 -- PROJECT UTV -- By the staff of Dirt Wheels Beverly Hills is a place where beauty is manufactured and the elderly get a new lease on life—well, in the looks department at least! Force Off-Road is a company that is veteran-run, and they outfit UTVs and other off-road toys with aftermarket upgrades. This means that they also get to give elderly UTVs new parts that help them keep living in their golden years. Scott Scurlock is a part of the Force team, and he purchased a tired Polaris RZR XP 4 900 from one of the Force…

YAMAHA YFZ450 WITH 200 HORSEPOWER!

-- Hey wait, that's a 4-cylinder engine! -- Upon further review that's not a single cylinder engine. It's got 4 exhaust pipes and 4 intake tracks, so there's no way it can be a YFZ450 engine. Maybe we should read what James Masephol said about his quad in his Email to us. Well, it did indeed start out as a 2005 Yamaha YFZ450. However he took the engine out and installed the engine from a Yamaha R1 street bike. Those 1000cc 4-cylinder engines make about 180 horsepower stock, and James figures his gets more like 200 with the…

PROJECT CAN-AM X3

-- Bolting on just about every accessory part available -- Russell Porter has the enthusiasm of a happy-go-lucky child in a man’s body. Buggy Whip, his successful family company, needed a rolling UTV showcase to help promote its products. Russ jumped like a kid in a candy store at the prospect of turning a Can-Am Maverick X3 X rs into a wicked display car. Buggy Whip has a great reputation, so many leading companies were ready to participate in the build. Russ was able to pick and choose, but he did a lot of choosing,…

YAMAHA YFZ WITH 160 HP

-- Reader hops up his Yamaha 450 quad -- Modern 450 quads like Yamaha's YFZ450  have such high-tech engines it's hard to extract much more power than what they come with stock. David Armitage in Illinois found away around that rule. However, you may say he cheated when he took out the single-cylinder 450cc engine. Instead he installed a Suzuki GSXR 4-cylinder street bike engine in his YFZ. When those things are revving up past 10 grand they produce around 160 ponies. That's about three times the horsepower of a stock YFZ.…

HONDA TRX363R TEST

-- Building the ultimate 2-stroke quad -- Honda TRX250Rs don’t have fans. They attract devotees—riders and owners with a two-stroke obsession that infests every cell with a sneaky efficiency that would make a papa virus proud. Like many TRX250R obsessions, Eric Christiansen’s started out many years ago. When he bought this machine 20 years ago, it was a wedding gift for his wife. Yes, we have all heard the “it’s for my wife” line before, but she actually spent a lot of time riding it for the first six years they owned…

PROJECT POLARIS RS1

-- Single seater build by Sector 7 -- Pro Moto Billet has been an innovator in off-road for many years. It started with billet parts, added Fastway to the stable, and now has brought its own brand of innovation to the UTV market. Its signature UTV part is a truly exceptional mirror set with powerful built-in lights that illuminate ahead and to the side. Do we have lights available? Or mirrors? Certainly, but Pro Moto Billet’s UTV arm, Sector 7, is combining both in a quality, innovative package. PMB is a family company,…

HONDA TRX480R

-- Refresh your older quad with a big-bore kit -- With many ATV manufacturers not producing sport ATVs any longer, many riders are having to hold onto older quads and rebuild them to as-new condition. Luckily, there are many ways to use aftermarket parts to rebuild your older sport ATV into something that is better than what you could pick up on the dealer-room floor. The project can even be at a cheaper cost if you don’t go crazy with your build. We recently had the chance to resurrect a 2004 TRX450R that had a blown…

RADICAL RZR PHOTO GALLERY!

-- MODIFIED FOR THE MUD -- With the right set of tires and some extra ground clearance you don't worry as much about getting stuck. You simply blast right on across the soggy bottoms with a smile on your face. It also feels good if your machine looks rather stylish as you roost past ordinary stock UTVs. If you're wondering how your RZR would look if you changed the color and added a few custom parts here and there, then take a look at these. They should help give you some ideas. The RZRs shown here were built by S3 Power…

PROJECT WILDCAT TRAIL 700

-- And it can still be hauled inside a van! --  By the staff of Dirt Wheels - This could be the lowest-budget UTV project that we have ever covered in Dirt Wheels. Derek Hunt and his brother Chris spend their days creating incredibly exotic electric bikes for their company, Hi-Power Cycles (www.hi-powercycles.com). Don’t tell anyone, but despite their penchant for things electric, the brothers harbor a fondness for things powered by gasoline. Very few of their high-end electric bikes cost less than what Derek forked…

SUZUKI QUADRACER 250

-- Custom rebuild on the first 2-stroke performance quad -- Honda's TRX250R gets most of the attention, but it actually owes its existence to Suzuki. The Quadracer 250 came out in 1985 while Honda, Yamaha and Kawasaki were focussed only on 3-wheelers. At that point Honda set its engineers on building a high-performance 2-stroke 4-wheeler to compete with the Suzuki. Granted, Honda did a good job with their very first effort, but that wouldn't have happened without using the Quadracer 250 as a reference. Here is Jay…

MONSTER RZR

-- XTC's superhero of UTVs -- By the staff of Dirt Wheels You never know what will set a person on a path to success. The trip to this scratch-built, 450-horsepower not-a-Polaris began many years ago when Chris Leaming’s father Rob gave him a new Yamaha Tri-Zinger 50cc three-wheeler for the SoCal deserts. The little Yamaha ignited a lifelong spark of off-road passion. The father-son duo are now partners in Gilbert, Arizona-based XTC Power Products. They moved there to grow the company that specializes in UTV…

POLARIS RZR XP 1000 PROJECT BUILD

-- RANCHO RACING'S RADICAL RZR -- By the staff of Dirt Wheel UTV racer Adrian Orellana didn’t drift into the sport by buying a recreational car and gradually adding to it. He bought a brand-new Polaris RZR XP 1000 and immediately tore the entire car apart and delivered the frame to Fabwerx. Fabwerx had no qualms about cutting nearly the entire stock frame away. Basically, Fabwerx started with the two main-frame rails and constructed a new racer from that starting point. Orellana’s race team is Rancho Racing. Rancho…
