Yamaha’s Grizzly 700 is a proof of Yamaha’s dedication to developing state-of-the-art technological advancements and is a successor to the popularly known Grizzly 660. The Grizzly 700 is a moderately bigger ATV and it has addressed many of its precursor’s common flaws. The best part yet, Yamaha made these changes while sticking to the true strengths of the lineage.
Despite having its minor imperfections, the Grizzly 700 retained the Grizzly’s position in the ATV market. However, this model isn’t known for its top speed, but the 4-wheeler still packs a lot of firepowers. In this article we’ll share details about the Yamaha Grizzly 700 top speed, and specs.
Yamaha Grizzly 700 Specs & Features
The advent of technologically advanced quads called for a significant upgrade to the Grizzly 660 into a machine that could go head-to-head with leading name brands in the industry. Hence, the birth of the Yamaha Grizzly 700 — a mean workhorse that features a 32-bit ECU for electronic power steering. The Yamaha Grizzly 700 also features a more extensive 686 cm3 displacement, and a 44-mm throttle-body fuel injection.
Here are the top specifications of the Grizzly 700.
Engine:
The Grizzly 700 features a four-stroke, liquid-cooled SOHC engine with a single-cylinder arrangement, forward-inclined, and a 102 x 84 mm bore-stroke ratio. In addition, it has a 686 cm3 engine displacement, a wet sump lubrication system, and a 9.20:1 compression ratio.
Fuel:
The Grizzly 700 comes with a fuel tank capacity of 5.28 US gallons/20 liters, with a 1.19-US gallon/4.5-liter reserve. The Grizzly 700 is also quite fuel efficient, as the ATV can give you roughly 90 – 95 miles per tank.
Lubrication:
The Grizzly’s oil capacity at oil filter change is 2.22 US quarts/2.10 liters and 2.11 US quarts/2 liters at disassembly. For top-end performance, the Yamaha Grizzly 700 oil type is 10W-30, 10W-40, SAE 5W, 15W-40, 20W-50, or 20W-40 Yamalube 4 four-stroke oil or equivalent motor oil.
Drivetrain:
This ATV utilizes An Ultramatic, V-belt shaft drive and a left-hand-operated centrifugal clutch to deliver power to its wheels. The Grizzly’s clutch system allows four-wheel downhill engine braking and maintains continuous belt tension to reduce wear. It also features a five-position shift lever with H, N, L, P, and R for easier handling.
Dimensions:
The ATV’s overall dimensions are 2,065 x 1,180 x 1,240 mm – L x W x H (81.3 x 46.5 x 48.8 inches). The base ground clearance is 275 mm (10.8 inches), while its wheelbase is 1,250 mm (49.2 inches). The Yamaha Grizzly 700 weight of 294 Kg/648 lbs makes it slightly heavier than the Grizzly 660.
The Grizzly’s stronghold in the ATV market is attributed to its pragmatic yet advanced features, and that’s why it is regarded as one of Yamaha’s most powerful ATVs.
Yamaha Grizzly 700 Top Speed
The top speed of Yamaha Grizzly 700 is quite impressive for a utility ATV designed for more low-end power and torque than top-end speed. For models that are still in fully stock condition, they can hit a top speed of about 65 – 66 mph, with an estimated fuel economy of 21.44 mpg (10.97 liters/100 km). In newer models, the Yamaha Grizzly 700 horsepower is 50 hp — a 6% increase from its previous models.
With that said, many pro-off-roaders still want more speed from their Grizzly 700. If this is you, there are some upgrades you can make to push the Grizzly’s top speed up into the 75+ mph range. The result will place it on par with other well-rounded ATVs that deliver top-end speed.
Yamaha Grizzly 700 Upgrades
Air Intake Modification
The Grizzly’s air intake consists of several components, such as the air filter and air box, which enables the engine to breathe properly. Like other Yamaha quads, the Grizzly’s built-in intake system chokes out the higher RPM levels, limiting its top-end speed.
To counter this, You will need to upgrade the stock airbox to allow more air in. Simply remove the airbox lid or change it altogether to improve airflow. You’ll also have to modify the stock air filter to ensure this increased airflow is free from debris and dirt that can harm the engine.
Ideally, Upgrading the air intake will increase the amount of clean air getting to the engine, increasing the power it can generate, particularly in the higher RPM ranges.
Exhaust Modification
Upgrading your air intake system can do more harm than good if your Grizzly cannot exhale all that added airflow. This is why upgrading your built-in exhaust system is also quite important. By modifying the stock exhaust system, it will help provide the extra airflow with an effective exit.
To achieve this you may want to replace the entire exhaust system. This upgraded exhaust system will increase the overall horsepower and torque generated throughout all its gears. However, it doesn’t end there, as the upgraded exhaust will also give the Grizzly 700 a more aggressive growl while riding.
Best Aftermarket Exhaust Systems For The Grizzly 700:
- Barker’s Exhaust.
- HMF Exhaust.
- RJWC Exhaust.
- Empire Exhaust.
While the power increase all these exhaust upgrades provide should be similar, their sound styles and output vary significantly.
ECU Tune With Fuel Controller
After adjusting the amount of air flowing in and out of your quad, it’s also entirely crucial that you modify your four-wheeler’s electronic control unit (ECU) to account for the increased air flow. When upgrading the air intake and exhaust systems, you must also ensure the appropriate amount of fuel flow.
The tuned ECU works together with the fuel controller to adjust and recalculate the appropriate air-to-fuel ratios and makes the fuel adjustment required relative to the extra airflow. This will enhance throttle response, speed, and horsepower at each throttle position and RPM level. In addition, this will also make sure that your engine is not harmed by upgrades you performed to the intake and exhaust systems.
Note: These upgrades don’t guarantee that the results will be the same for everyone. Weather conditions, riding style, and terrain are some external factors that could affect the Grizzly’s top speed even after the upgrade.
Conclusion
Stock or upgraded, Yamaha’s Grizzly 700 is one powerful ATV that will satisfy anyone’s adventurous desires. Its specifications also cater to riders of all skill levels and ages. While its top speed of 65 – 66 mph might not keep up with the faster ATVs in the market, it still packs a lot under the hood to thrill riders.
