Newest Grizzly raises the bar in 450 class
Leaping into a land of tight trails, multiple elevation changes and over 90,000 acres of pristine forest made me excited to be in the world of ATV journalism. The test of machine and man would also be the challenge set forth by our friends at Yamaha Motor Corporation in the Capitol State Forest and with the new Yamaha Grizzly 450 EPS as our valiant steed it was sure to be a great adventure.
For the model year 2011 Yamaha has added not just a revamped version of an old puddle buster, but also a totally new and fine-tuned version in the small displacement utility line up. Getting the most bang for your buck these days counts and the new Grizzly 450 4X4 EPS could possibly be the best overall performer for the discerning consumer.
Getting a facelift was not in the plans for the Grizzly 450. What lies beneath the plastic clothing was what really counted and in traditional Yamaha fashion that’s where the focus was. With a new frame, redesigned braking and the ever-popular power steering finally making its debut in the Grizzly 450 this was going to be an interesting ride.
With the biggest news being the power steering one might immediately begin to dream of a stress free casual trail ride without the annoying arm pump and intimidating tough rocky sections that seem to suck the life out of the average recreational trail rider. This would surely mean longer seat time and a more enjoyable experience. Electronic power steering is no stranger to the Yamaha Grizzly line as the 550 and 700 utilize the same exact system, but the ECU has been updated specifically for the 450. This award winning set up is torque and speed sensing engineered to reduce any nasty feedback, which helps reduce fatigue at the same time. The power steering also helps absorb sudden shock from trail debris like rocks and stumps, which allows the rider to maintain control.
Another great redesign was in the frame of the Grizzly 450 EPS. The old-style frame had a “bolt in” style independent suspension on the back end. The new skeleton has become a one-piece frame that is 10 percent lighter than the previous model and overall the new non-EPS Grizzly weights 22 pounds less than its predecessor. The addition of the EPS will bring the weight back up almost ten pounds, but the versatility and comfort it brings is well worth the small weight penalty.
A few years back the forward-thinking minds at Yamaha set out to develop the ultimate braking solution for utility ATV riders everywhere. After a few years of tweaking, this design has been completed and can now be found on the new Grizzly 450. The brand new rear brake, or wet brake as Yamaha calls it, will set the mark for future generations. This system employs a sealed clutch pack set up that applies braking to the pinion shaft. This brake application is then multiplied through the gearing of the rear end, which makes stopping the machine a lot easier with less effort. Having the braking components sealed and being bathed in the rear differential fluid means they stay cool and clean. As long as the fluid in the rear end stays at the proper level and remains clean these brakes should work flawlessly.
Other notables on the Yamaha Grizzly 450 4X4 EPS ($7,499 – $6,899 for non-EPS version) for the model year 2011 include the same great Ultramatic automatic transmission that has set the bar high for our industry in reliability and durability. This automatic tranny also has engine braking for the steep descents on the trail. The front suspension has been reengineered to accommodate the new EPS and this has resulted in the addition of a rear sway bar to help level out the changes on the front.
Storage on the light and nimble Grizzly 450 is at a premium but not forgotten as the sealed front fender storage capsule is accented by a non-sealed under seat compartment for a little more junk in the trunk. The same great digital dash will tell you what is going on with your Grizzly and a backlit display means you can even see this info in the dark. From full rack capacity on the front of 88 pounds to a hefty 176 on the rear, there should be no trouble carrying a workload on the ranch. This Grizzly will also tow up to 1,322 pounds for those who may need to.
The really exciting part of our adventure wasn’t left in the plush dining hall but rather in a much more suitable surrounding and a proper home for a Grizzly, the Capitol State Forest. This ride area is home to tight trails and extreme elevation but for a brief time in my life it was my home with the new Grizzly 450 4X4 EPS.
Taking the Grizzly into the thick tree line we began to feel at home. The seating on the Grizzly 450 is plush and comfortable. We seemed to have plenty of room, even though we do fall a bit on the larger side. The controls on the handlebar fit directly into our ergonomic needs and with a quick look around the cockpit it was time to unleash this 450cc powerplant. While the Grizzly 450 is no great powerhouse, it’s certainly no slouch either. This machine can be opened up and really gives even the experienced rider a great trail ride.
Handling is as good as can be expected from a utility. Our Grizzly 450 stuck to the trail and remained stable in fast cornering situations. Power steering was very welcomed at low speeds and with the trees in the Capitol State Forest jumping around in front of us it really makes the brushes with bark a little less dramatic. Rocky sections in this forest are intense and this is yet another area where the electronic power steering would shine.
We noticed only a couple of things we’d change on the Grizzly 450 and one was more grip in the peg area. The stock pegs just didn’t seem to be aggressive enough for our style and a kick up on the end would also be nice. We would probably move the rear brake lever down and out just a bit as well so we could find it when we really needed to get the ride stopped. The only other requirement would be more seat time to enjoy the best-kept secret in the utility market!
Riding for over four hours straight and not feeling beat to death was refreshing and this machine lets you take it to the edge with your buddies while maintaining its workaholic roots.
