To say that the Yamaha Warrior 350 is a phenomenal vehicle under Yamaha’s product line of ATVs would be an understatement. First released in 1987, the Yahama Warrior 350 became a classic all-terrain vehicle among thrill-seekers and power sports enthusiasts worldwide, alongside other ATV brands.
One of the most amazing qualities of the Yamaha Warrior 350 is its user-friendly features, which enabled beginners to handle this vehicle with extreme efficiency. Apart from that, this ATV has an electric starter system, a six-speed transmission, and a reverse lever gear—which added that much-needed convenience and practicality to its already admirable set of capabilities.
With its 4×2 drivetrain, the Yamaha Warrior 350 can trek across rocky and muddy trails, as well as areas with shallow water, such as swamp holes. This single-seater owes that versatility to the snorkel air intake kit, which allows this ATV to traverse areas with shallow water. Though Yamaha ceased production in 2004, the quad continued to maintain its iconic status as one of the most reliable and versatile quads, thanks to its four-stroke, single-cylinder, SOHC engine, which maximizes fuel efficiency and power.

Yamaha Warrior 350’s Specifications and Other Details
The Yamaha Warrior 350 has an air-cooled 348cc four-stroke, single-cylinder, single overhead cam (SOHC) engine configuration, which keeps the engine from experiencing breakdowns. With a 38-millimetre Mikuni carburettor, and a bore-to-stroke ratio of 83 x 64.5 millimetres, the Warrior 350s engine has a compression ratio of 9.2:1. Also, ATV variants from 1987 to 2000 use an NGK Standard ND8EA spark plug.
The Yamaha Warrior 350 uses oil types that range from 10W-30 to 20W-50. With the oil filter on, the oil capacity is 2.6 quarts. Though a 10W-40 oil type is suitable for high mileage, 20W-50 will be ideal for warmer climates. In this case, be mindful that the oil type should be apropos to the vehicle usage and ambient temperature.
This quad has a six-speed manual transmission and comes with a reverse lever gear located under the seat right above the engine crankshaft. The Yamaha Warrior 350 has a rear-wheel primary chain drive and has a 4×2 drivetrain O-ring chain.
This quad sports an independent double wishbone front suspension with an adjustable fork preload capability. The Yamaha Warrior 350 also has a rear swing arm suspension with an adjustable rebound damping, which enables the ATV to absorb as much shock as possible even in rapid succession. In addition, there are 7.9 inches (200.7 mm) of travel for both the front and rear wheels.

The Yamaha Warrior 350 has tubeless aluminium wheels. The quad’s front tyres are equipped with AT 22 x 7-10, while the rear tyres have AT 22 x 10-9. The Warrior 350 is fitted with two brake systems: single-lever dual hydraulic discs in the front and another hydraulic foot brake disc in the rear.
The full length of the Yamaha Warrior 350 is 6.03 feet, while its width and height are both 42.5 inches (1079.5 mm). The wheelbase for this ATV is 47.2 inches (1198.9 mm). Furthermore, the ground clearance is 4.9 inches (124.5 mm). Additionally, the seat height of the Warrior 350 is 30.1 inches (764.5 mm).
The Yamaha Warrior 350 has a fuel capacity of 2.4 gallons (9.1 litres). In the early models, however, the fuel capacity can hold up to 3.2 gallons. Meanwhile, the engine has a displacement of 0.88 ccs. Despite its size, this sports quad has a 400-lb. weight-bearing capacity.
Apart from a steel frame build, the body material of the Yamaha Warrior 350 is plastic.

Tips on Augmenting the Exterior of an Old Yamaha Warrior 350
Even though production has stopped for the Yamaha Warrior 350, aftermarket components and other equipment can still be found and bought far and wide. This fact is a testament to the Warrior 350’s reputation as a highly adaptable, all-terrain quad. If you want to improve your Yamaha Warrior 350, we may have some advice that you may find valuable.
Changing the Tyre Sizes
Superb handling first starts with better tyre components. In this case, you may want to replace those OEM tyres with racing variants. With this tyre type, your Yamaha Warrior 350 can perform better on tight corners. Also, you will be making your tyres resistant to puncture.
If you want to upgrade the tire size, you may opt for these alternative sizes: AT 23 x 7-10 for the front tires, while AT 22 x 11-9 for the rear. Some riders go for these said sizes especially if standard-sized racing tyres become hard to find. You’ll be wise to note that you can only go an inch higher both in width and height for the Yamaha Warrior 350. Anything larger than that will give you clearance issues.
Replacing the Handlebar
If you plan to replace the handlebars on your Yamaha Warrior 350, one of the qualities that you should consider is the material. There are two types that you can choose from; those are steel and aluminum. Most riders prefer having the aluminum variant because of its durable and lightweight design. Steel handlebars are also a good option. With regard to this component, however, you may want to consider your budget. That’s because in most cases, the higher the quality, the costlier it will be.
Also, take note of the size of the handlebar because not all models come with the same diameter. For instance, the 2002 to 2004 Yamaha Warrior 350 models have a diameter of 1 inch, but the 2002 and 2003 models differ from the 2004 model in terms of the bend—that’s the width, height, pullback, and centre of the handlebar.
Regardless of what you want to have on your Yamaha Warrior 350, it all boils down to having better control and a comfortable grip. You can find several choices of aftermarket handlebar designs online that will definitely suit your need.
Modding the Undercarriage and Arm Guards
The Yamaha Warrior 350 does indeed have a bulletproof engine, but that does not mean it’s bulletproof all over. Protecting the vulnerable components of this quad may come at a cost. However, if you’ve come a long way from, say, improving the engine and all other minor parts located in the undercarriage, you might as well add something to prevent unwanted damages.
For that matter, you might want to install a skid plate to protect the chassis and other components on the underside of your quad from obstacles, such as trail bumps or rocks, and other loose debris. On the same note, adding guards for the A-arms and swing arms in the front and the rear suspensions, respectively, can protect these components from impact and may even extend their lifecycle for that matter.
There are several aftermarket skid plates and A-arm and swing arm guards available online for your Yamaha Warrior 350. You can install these items on your own or have an expert do it for you.
What Is the Top Speed of the Yamaha Warrior 350?
With its 19 horsepower, four-stroke engine, a Yamaha Warrior 350 stock model can reach speeds of up to 63 mph on flat and even surfaces. There are, however, other factors that can affect the Warrior 350’s top speed, such as the weight of the rider and weather. The condition of the vehicle, as well as any modifications fitted into the quad, may also affect its performance.
Some people tend to upgrade their Yamaha Warrior 350 quads to boost their speed and horsepower. Riders can ramp up the Warrior 350’s horsepower by 2 to 3 points higher by installing a slip-on exhaust. (Of course, you’ll have to remove the stock exhaust for that matter.)
The only drawback to this setup is a louder muffler sound. If you want to lower the noise, get either get a noise eliminator or spark arrestor for your muffler. You can purchase these products—the slip-on exhaust included—as aftermarket equipment.
What Are the Pros and Cons of the Yamaha Warrior 350?
The Yamaha Warrior 350’s power and engine performance gave this vehicle a place in history’s awesome ATVs of all time. The quad’s all-terrain capability and durable configuration have prompted several ATV enthusiasts to add mods and upgrade their Warrior 350s, the year and model notwithstanding. In addition to the abovementioned features, we highlight some of the salient benefits of the Yamaha Warrior 350.
YAMAHA WARRIOR 350’S ADVANTAGES
What makes the Yamaha Warrior 350 unique during its time was that it is fitted with a reverse gear shift lever. The reverse transmission provides riders manoeuverability, especially in spots that require them to backpedal efficiently. This feature is seen both as a convenience and necessity which may probably continue to be revered and appreciated by most Warrior 350 riders.
There are, however, instances in which some riders are unaware of the reverse lever. This is common among riders who bought a pre-used model and were not given a proper walkthrough of all the Warrior 350’s features. The other factor which contributes to some riders being unaware of the reverse lever is situated under the saddle, specifically at the right side of the engine crankcase.
To use the reverse lever, put the Yamaha Warrior 350 to neutral. Then turn the clutch and pull the lever backward in the direction of the rear tire. The reverse light should light up if you performed these steps properly. Otherwise, you have to pull the lever all the way back. Once you release the clutch, the ATV should back down as expected.
SOHC Engine Design
The Yamaha Warrior 350 has a single overhead cam that prevents the engine from having cam phasing problems. This scenario happens when the intake and exhaust valves open and close at later or earlier, which may result in engine damage. This engine configuration is easier to understand and comes in handy especially for riders who have no experience with more advanced engine designs, especially for those who want to upgrade or modify the engines themselves to improve the Warrior 350s torque or speed.
Unlike most ATVs, the Yamaha Warrior 350 has a six-speed transmission that provides less fuel consumption. Otherwise known as the overdrive, this setting increases the quad’s fuel economy, while greatly decreasing CO2 output. On top of that, this feature gives the Yamaha Warrior 350 smoother performance and speed, making it one of the most definitive sports ATVs of all time.
YAMAHA WARRIOR 350’S LIMITATIONS
As a sports quad, the Yamaha Warrior 350 is built for torque and speed, so some riders like to use this ATV as a quality, thrill-seeking experience. However, some riders find the saddle a bit low, which can be a bit hard on the knees, especially those who like to stand up a lot for a sitting position. Despite this issue, however, it’s wise to note that the seat height of a stock Yamaha Warrior 350 is designed for better balance and centre of gravity.
Outmoded Suspension System
One of the Yamaha Warrior 350’s issues is its suspension. Some riders find the suspension on the Warrior 350 somewhat stiff, which is why people acquainted with this quad would advise anyone not to use it on dunes. That is because there have been no changes made in the design of the vehicle’s suspension systems ever since these ATVs have not been halted in production in mid-2000s.
Additional Pros and Cons of the Yamaha Warrior 350
· Bulletproof engine, which adds to superior, quality design.
· Easy electronic start switch.
· Availability of aftermarket parts and switchable components with other Yamaha sports ATVs like the Raptor and Banshee.
· Extremely cost-efficient for an ATV with consistent power and speed.
· Choke lever for cold start problems.
· This vehicle is perfect for trail-riding.
· The quad has a decent load capacity of 400 lbs.
· Handlebar design may be a bit higher for riders.
· No skid plate, which makes some of the undercarriage components vulnerable to ricocheting debris.
· The quad’s heavy frame and narrow build makes the vehicle unsuitable for wider tracks.
What Makes the Yamaha Warrior 350 a Popular Sports ATV?
The designation “best-selling sports quad worldwide” is not something the Yamaha Warrior 350 earned out of sheer luck. As one of the first sports ATV ever made, the Warrior 350 is a trailblazer in terms of speed and design. The six-speed transmission and the reverse lever made the Yamaha Warrior 350 a reliable vehicle for any occasion. Also, the 4-stroke, single-cylinder, SOHC engine gives this all-terrain, four-wheeler ample torque and acceleration.
