Honda ATVs: In It for the Long Haul

With powertrains that are built to outlast everything else on the market, Honda ATVs have a well-deserved reputation for reliability. It’s common to come across units that are still used regularly despite ages well into the double-digits. One example is Craig West’s 1998 TRX300, a precursor to the original, 2000 Rancher. A recently retired businessman who lives on a 73 acre ranch in the Sierra Nevada foothills of Sonora, California, West rides his ATV almost exclusively for utility purposes. “We graze cattle to keep the grass down, but the main thing we do is cut firewood,” he says. “The land is covered with oak trees, and although I never cut them down, they often fall on their own. It’s hilly property, and we access the fallen trees on the ATV and tow out the wood in a trailer. We also use it to haul tools and supplies for repairing the fences.”

The little TRX was slightly used when West purchased it in ’99, and he figures it has been utilized an average of once per week ever since. Amazingly, it’s still on its original tires, but apart from a dent in the gas tank (the result of a wayward falling limb during a vigorous pruning session), it still looks surprisingly good. “I wait for it to die, but it just keeps running,” he laughs. “That’s what Hondas do. I think I’ve changed the battery once in 15 years, and I do the basic maintenance every third year or so.”

West’s children (a college-age son and a daughter in high school) grew up alongside the ATV, and these days they regularly ride it when helping Dad around the ranch. The kids now possess impressive trailer-backing skills that were honed both with the TRX itself and with the trailer upon which it is sometimes carried. West says the 300 has practically become a member of the family, but after pausing for a moment, he reconsiders. “Well, I have to admit I wouldn’t mind having the additional power of the newer models,” he says. “I could probably really haul a lot of wood with one of those….”

Honda Automatic DCT: The Ultimate ATV Transmission

Back in 2007, the Rancher AT became the first Honda vehicle to feature an automatic dual clutch transmission. Today, Honda is still the only manufacturer to apply this technology to ATVs (it’s now also available on a number of Honda motorcycles). DCT offers the durability and the direct acceleration feel of a manual transmission, but with automated gear changes. For 2015, this acclaimed five-speed automatic gearbox has been refined even further.

Honda’s DCT features two mainshafts (the first is hollow, and the second resides within the first), each holding its own clutch. The first mainshaft/clutch combination works with the odd-numbered gears while the second combination works with even-numbered gear sets. Through this arrangement, the next gear is always pre-selected, so when one clutch hands off to another for a gear-change, shifts are quick and smooth.

Automatic DCT offers a number of advantages over standard systems:

Reliability: DCT is a sealed system, so it’s protected from the extremely harsh environments common in ATV use. In addition, there’s no belt to wear out or break.
Efficiency: Because DCT uses actual gears rather than a belt and pulleys, there’s significantly less power loss between the crankshaft and the wheels.
Smoothness: Shifts are smooth and quick with automatic DCT, with minimal power gaps during shifting. In addition, the fact that shifts are controlled by the ECU means that clutch “feathering” is engineered in to ensure ideal gear changes, which is one reason that DCT is popular in pure-performance applications such as high-end sports cars.
Control: Honda’s automatic DCT offers the possibility of switching to manual, push-button Electric Shift Program (ESP). “Some users like to shift for themselves during sportier-style riding,” explains Honda R&D powertrain engineer Scott Batdorf. “Also, for pure utility use, it can be nice if you’re towing a big trailer.” Additionally, whether in automatic or manual ESP, the rider benefits from true engine braking when descending.

For 2015, Honda has improved the DCT on the Rancher by revising the algorithm to reduce shift-shock even further, and to optimize the logic of the new-generation dual-zone shifting for improved shift timing. By analyzing data such as frequency of throttle-setting changes and throttle setting versus vehicle speed, the ECU automatically adjusts between two shifting maps—Cruise or Sport. “During casual riding, the map is set to keep revs lower, for comfort and fuel efficiency,” says Honda R&D engineer David Karo. “If you start riding in a sportier manner, the ECU detects that and switches to a more aggressive map that changes the shift pattern to hold gears longer.”

Serious Fun
Brian Walters on developing the Rancher Automatic DCT with IRS

As a top motocross racer who won his class in the 1989 AMA Amateur Nationals at Loretta Lynn’s and later competed as a pro in the AMA Supercross
and White Brothers Four-Stroke series, Brian “Spud” Walters never imagined he would eventually find work developing ATVs. Nevertheless, now that he is ATV Test Project Leader at Honda R&D Americas, he finds himself drawing heavily on his motocross background. “When I took the job to help develop ATVs for Honda in 2007, I was kind of unsure,” Walters admits, “but I adapted immediately. My feel for controlling two-wheel vehicles actually helped and made it easier to understand the dynamics of ATVs.”

In the case of the 2015 Rancher Automatic DCT with IRS, Walters’ background may have been most useful in developing the vehicle’s recreational capabilities, as sensing what traits are best suited for that application comes naturally to the ex-racer. From there, it was a matter of developing the features that would provide those characteristics. One of those was the improved independent rear suspension compared to the Rancher’s previous IRS version. “The new IRS base that we’re using is really good,” Walters says. “It’s very similar to that of the new 2015 Foreman Rubicon, but the action is a bit firmer, for a sportier feel—a great balance between comfort and stability. Compared to the Rubicon, the wheels are an inch smaller to achieve a lower overall vehicle, and the rider triangle—the relationship between the seat, handlebar and footpegs—is lower as well.”

Meanwhile, Walters’ development team drew inspiration for much of the vehicle’s bodywork from the Rancher’s swingarm version, resulting in a narrow seating area that provides a nimbler, more compact feel, along with the aggressive-looking front end.  Walters also feels that the automatic DCT is perfectly suited for a recreational application. “It’s definitely a lot more responsive than CVT, and as a result, there’s more of a fun factor,” he explains. “It has a torquey feel, and since it’s sealed and mechanical, you don’t have to worry about water getting into it and messing with a belt.”

That durability is vital for an ATV that’s sure to see a significant amount of recreational use, and Walters is confident that the Rancher Automatic DCT with IRS is up to the task. “We definitely pushed this one pretty hard during testing,” he says. “Obviously, it’s not designed to be used on a motocross track, but we rode it hard and went through endless rock gardens and creek crossings. This ATV will hold up to anything you put it through.”

If anyone would know, it’s Spud.
