If we hadn’t ridden the MXZ Blizzard first, we’d be all over the 2016 Ski-Doo MXZ TNT 1200 4-TEC as one of the best trail sleds for next season. But we did ride the Blizzard and took a shine to the extra bite and bump bridging you get with its 129-inch track versus the standard 120-inch Ripsaw track on the TNT. Other than that, we were quite impressed with the new for 2016 TNT 1200 4-TEC.

The 1200 4-TEC entered the Ski-Doo scene housed in a series of 2009 models, including the TNT. It was a big deal for Ski-Doo as it gave them a triple-headed competitor to Yamaha’s Vector and Nytro. While an important new engine back then, it was not Ski-Doo’s first four-stroke, that was the V-1000 introduced in 2003 and followed by the V-800, which delivered nearly 25 miles per gallon and greenish emissions.

The first 1200 4-TEC targeted the 600 category of performance sleds as it produced a claimed 130 hp, which is near the accepted norm for that class of sleds. But the 1200 delivered more than power comparable to 600cc two-strokes; it also produced a very smooth power band with peak torque and horsepower coming in at lower revs. The Rotax-engineered double overhead cam three-cylinder motor had a horsepower rating of 125 hp @ 7800 rpm. Its torque was 112 lb-ft at 7500 revs. Clutch engagement of the current 1200 4-TEC is listed as 2200 rpm, which means you can expect ample low through mid range pull from this engine.

Actually, at our West Yellowstone test site, we felt the 2016 4-TEC had significantly improved low and midrange performance. That comes as a result of Ski-Doo and Rotax engineers tweaking the 1200 to accept Intelligent Throttle Control, which provides three levels of switch-on-the-fly performance. Initially built into the 600 and 900 ACE motors, ITC needed to be retrofitted to the 1200 4-TEC. In the process the revitalized 1200 got an updated intake and total revamped engine computerization, plus the lightness of throttle-by-wire control.

Rotax 1200 4-TEC EngineIntroduced for the 2009 model year, Ski-Doo’s 1100cc four-stroke adds enhanced low end and midrange performance, plus a narrower exhaust that allows it to fit inside the REV-XS bodywork.

We have not been big fans of the somewhat gimmicky three levels of computer-actuated performance. We understand the concept and how it works, which, frankly, is simply and efficiently. But is it necessary? Tech lovers probably enjoy it and it is s-o-o much more preferable to tweaking a carbureted system. You have three choices: Standard, Sport and full-on Economy. A dash-mounted rocker style switch lets you make your performance choice as you ride.

If you want to win a bet as which sled gets the best mileage, opt for the ECO setting. It essentially shuts down aggressive performance, but does help meet Best Available Technology requirements necessary to make the sled legal in Yellowstone Park. The standard mode is a base setting; it gives you smooth, linear performance. The Sport mode spikes engine performance for maximum acceleration and such. Some of our test riders always set the 4-TEC to that setting while we backed off to the base mode. Admittedly the Sport mode is a personal choice, just not ours. Why not compromise and simply offer two modes: the Eco mode and a combined, more drivable, less herky-jerky mode?

2016 Ski-Doo MXZ TNT 1200 4-TEC Modes ButtonSimply rock the driving mode switch to engage one of three performance settings: Sport, Standard or ECO for maximum mileage.

Of course, we offer the same question to Yamaha, which also added multiple performance modes to its latest Vector triples. Interesting how both Ski-Doo and Yamaha made the same mode decisions in the same model year? Was NSA hacking and sharing their emails? (Just kidding NSA!)

Although the key feature for the 1200 4-TEC centers around its computer programming, some of that became necessary when Ski-Doo fitted a new, more compact and lighter weight exhaust canister. Supposedly none of these changes resulted in any increased power numbers, but the re-worked 1200 felt quicker and more responsive to us.

By narrowing the engine package, Ski-Doo engineers were able to fit the drivetrain within the confines of the REV-XS platform and narrower bodywork. The older 1200 4-TEC used the now outdated REV-XR platform, which was one of three variants of the REV-X platform.

2016 Ski-Doo MXZ TNT 1200 4-TEC RearStretching nearly 115-inches from ski tip to snow flap, the 2016 MXZ TNT 1200 4-TEC features a seat with storage, straight aluminum handlebars and ample room for accessories.

From that iteration of the initial REV chassis, Ski-Doo cleverly designed a modular frame that allowed three variants. The first variant was introduced in model year 2008 as the REV-XP and was 37 percent stronger than the old style REV. Two other variants, the REV-XR and REV-XU versions, followed in model year 2009. The XR, although based on the REV-XP, featured a different engine module to house the wider 1200 4-TEC triple. The tunnel section of the XU suited a wider 20-inch utility-oriented track.

At the introduction of the new chassis designs Ski-Doo noted, “The beauty of this system is that whether the vehicle is a ditch-banging MX Z, a high mileage luxury-touring GTX or versatile Expedition touring utility vehicle, they all share the same core benefits of the REV-X — incredible light weight, a more versatile riding position, mass centralization and better performance.”

Move ahead to model year 2016 and note that the MXZ TNT 1200 4-TEC now shares the same style platform and narrowed bodywork as the two-stroke engine TNT models. From a looks standpoint, the new 1200 4-TEC appears slimmer and more sporty. Looks can be deceptive, as the 1200 TNT, at 505 pounds, weighs nearly 50 pounds more than its 600 E-TEC counterpart. While we might like to make a big deal of that fact, we won’t as the 4-TEC can use its extra 10 to 15 horsepower and greater torque to nearly overcome the difference. Plus, you may get good mileage with the E-TEC but it won’t be as good as the nearly 20 miles per gallon you could get with the 4-TEC.

2016 Ski-Doo MXZ TNT 1200 4-TEC Action FrontThe smooth power of the MXZ TNT’s updated 1200 4-TEC makes sport riding immensely more fun.

Overall, the new for 2016 MXZ TNT 1200 4-TEC deserves praise. It’s a much sportier sled than previous versions. The REV-XS bodywork lets you get into the corners more aggressively to take full advantage of the RAS2 front suspension grip and smooth action of the rMotion rear. Each suspension component features rebuildable, aluminum-bodied HPG Plus shocks. Tuned to the needs of the 1200 4-TEC, the suspensions adroitly balance out the desires of a sport rider with the realities of a long distance trail rider. Its 120-inch Ripsaw track offers proven grip for quick accelerating and a quick response for turning into tight corners. If long days are your forte, consider that its 10.6-gallon fuel tank, at 19 miles per gallon, could let you cover 200 non-stop trail miles.

At US$11,849 the 2016 Ski-Doo MXZ TNT 1200 4-TEC offers good value as its provides the latest technology, including a learning key that can be programmed to dumb down performance for new riders, and famous MXZ on-trail handling prowess. The sled is very comfortable to ride, offers aggressive handling when you want it, or cruise mode when you don’t. With its newly revitalized four-stroke engine, the TNT 1200 gives you a durable, quiet and very fuel efficient snowmobile that can be counted on for many seasons to come.
