Polaris Scrambler 400: To meet the demand for more flexibility in the market caused by utility vehicles, Polaris launched the Polaris 400 Scrambler in 1995. From the start, this sports-oriented vehicle became popular with the public.
It was a delight for beginners who were exploring the pleasures of nature and experienced enthusiasts who were living and breathing sports.
One of the earliest progenitors of the most powerful 4-strokes ever built in history, this Polaris Scrambler 400 embodied the ideal of sports riding during the 1990s.
The sport-utility vehicle was a charming vehicle that provided quick power and was able to handle challenging conditions, which allowed for unforgettable adventures.
Its predecessor, the Polaris Scrambler 400 appealed to those who liked utility vehicles but did not completely make use of them for work in the yard.
With the advent of stricter emission standards, four-stroke engines as well as other advancements in technology The market quickly outgrew the 400-class 4×4 and switched its attention to the more modern Polaris Scrambler 500. That was until the advent of mud riding in the mid-2000s. The rise of project builds brought back 2-stroke engines.
What was the catalyst that started it all
In the early 1990s, sports riding was not a thing that could be translated into aluminium wheels or titanium coil springs or the massive air intake systems that are found in the modern pure sport ATVs.
For many skilled and professional riders, a four-wheel-drive was sufficient (and was, in actuality an uncommon feature).
The ability to have an independent rear suspension was an advantage. The most important thing was that the vehicle didn’t fall over during large jumps or if it went off-camber.
These were the characteristics of this 1995 Polaris Scrambler 400. Even though it had an axle straight in the rear instead of IRS it did come with the True On-Demand(TM) AWD Drive System that let riders ride without fear on slippery surfaces and mud pits without slipping or getting stuck.
With snappy power as well as a low center gravity and a long-travel suspension, the Scrambler offered a stable and comfortable ride.
Over the course of its production period of 8 years, it was the Polaris 400 Scrambler underwent significant enhancements.
The weight was taken off the car, reducing the weight to 481 pounds from 519 pounds. Concentric Drive System (CDS) was introduced in 1999 models and onwards. Polaris included the Fox Shox with a remote reservoir (view the remote reservoir on Amazon) on the back suspension.
It also increased the wheel’s movement by 7.5 to 8.2 inches in the front and 8.5 to 10.5 inches in the rear for models of later years. T
these modifications not only improve the handling of the four-wheeler, which is already excellent but also contributed to its Polaris Scrambler 400 top speed of 70 mph.
1999 Polaris Scrambler 400 Specs & Features Engine
Power is generated by a 2-stroke single-cylinder engine that is liquid-cooled that incorporates oil. It has an 83:1 bore-stroke ratio.
70 millimetres (3.27 2.76 inches) 2.76 inches) and the engine’s displacement is 378 cubic centimetres and the compression ratio is 6.9:1 (effective).
The Mikuni VM34SS carburettor is able to handle the mixture of air and fuel. The capacity of the fuel tank can be 4.0 US gallons/15.1 litres of unleaded gasoline, with an optimum PON value of either 85 (oxygenated) or 90 (non-oxygenated). Be sure to avoid using fuel that has an ethanol percentage greater than 10% in order to prevent damage to your engine.
The oil injector’s capacity can be two US quarts (1.9 Liters) in Polaris Premium TC-W3 2 Stroke Oil or equivalent. The shift selector requires 1 0.25 oz (30 millilitres) of Polaris 0W/40 Synthetic Engine Lubricant.
The API certification of any SJ engine oil which is in compliance with the specifications of the manufacturer and JASO the T903 MA standard that does not contain molybdenum-based additives will give you the best engine performance. However, using different oil types could need more frequent oil replacements.
A sophisticated true On-Demand(TM) AWD System, controlled by an on/off switch on the right handgrip, is a complement to the auto Polaris Variable Transmission.
The four-wheel-drive system automatically engages both front and rear wheels with full torque when the rear wheels are losing grip.
An O-Ring drive chain 520 along with a Hilliard clutch give force to the wheel. A side lever shift (with an F/N/R gearshift pattern) is used to control wheel spin.
The Scrambler comes with a DC-CDI (Capacitor Discharge Ignition) electric start system that includes an additional manual recoil starter.
It features ignition times at 23.5deg BTDC @ 3,000 RPM + 1.5 the charging device is a three-phase output alternator, with a maximum power of 150W.
A 14 Ah 12V 220-CCA (Cold Cranking Amps) battery that measures 5.28 3.54 x 3.54 6.54 6.54 inches can power the quad.
An NGK Spark plug BR5E with a gap that is 0.028 inches (0.7 millimetres) and the current 14AH-BS batteries (view the full list on Amazon) models will definitely work with the majority of Polaris Scrambler 400 models.
The four-wheeler has Carlisle(r) AT489 23X 7-10 front tires that are fitted with the steel wheel and AT48922 11-10 back tires.
The recommended the tire’s pressure is for front tires: 4 psi/27.58 (kPa) (0.28 kg/cm2) and 3 psi/20.68 kPa (0.21 kg/cm2).
In the event of wear or damage, replace your tires with the same size, or opt for larger tires and two-inch (50-mm) 4×156 wheel spacers (view at Amazon).
It uses fixed hydraulic floating-calliper front discs and fixed hydraulic, opposed-piston-calliper discs for the rear and auxiliary brakes.
Models from the ’00 model and beyond utilize single lever, all-wheel hydraulic disc brakes as well as a hydraulic rear foot brake.
Like all Polaris ATVs suggest DOT 3.0 brake fluid while making repairs or assembling brakes to stop the expansion of rubber components and to prevent contamination.
Scrambler’s Scrambler front suspension features a MacPherson Strut that has 8.2 inches (208.3 millimetres) of travel.
The rear suspension is a rear progressive-rate swingarm equipped with the ability to adjust the thread of the mono-shock, which is adjustable and provides 8.8 inches (223.5 millimetres) of movement.
The car’s length overall and 48.5-inch wheelbase contribute to its turn radius, which is 5.0 inches (60 inches) which allows for more precise corners and turning angles.
The overall dimensions include 74.5 inches x 45.5 47 inches (1,892 1 x 1,156 1194 mm – L x W and H).
The seat height of the quad of 33 inches (838 millimetres) and the minimum floor clearance (unloaded) of 6.5 inches (165 millimetres).
The dry weight of 519 pounds (235.6 kg); GVWR is 845 pounds (383.3 Kg) which is a mix of curb weight, and rack capacity of 90 pounds (40.8 Kg) as well as accessories, cargo, as well as passengers.
Tongue and towing capacities for weight are 850 lbs (385.5 kg) and 30 pounds (13.6 Kg) in each case.
The Gen III type steel frame is finished in a medium gloss black finish and comes with a polymer body panel that is available for purchase in Fire Red, Blue, and Bright White.
The rear and front fenders as well as a front-facing brush guard, handgrips, and floorboards with full handles and two dual-beam Halogen quartz headlights are standard equipment.
Additional accessories are available from dealerships as optional features for vehicles that are brand new.
For building initiatives, it is possible to buy accessories from aftermarket Polaris Scrambler 400 parts from auto shops and online retailers.
On-Demand(TM) AWD/2WD Drive Systems
This feature is offered for Polaris Scrambler 400 4×4 models and can be activated using the two-position switch located on the right handlebar.
It lets the front axles instantly engage any moment that the rear wheels are unable to regain traction.
This reverse happens as the rear wheels get traction. This feature was one of the most popular features on Polaris ATVs prior to the advent of Independent Rear Suspension.
Concentric Drive System
Because of CDS CDS, the rear suspension’s entire range is possible to use without compromising the power supply towards the back wheels.
This Polaris feature is designed to align the swingarm’s pivot point to the drive sprocket’s centre and results in constant chain tension, less chain wear, and less need for maintenance or adjustment of the chain.

Polaris Scrambler 400 Top Speed
The maximum speed of the Polaris Scrambler 400 can reach 70 mph. It is astonishing that it surpasses its 500-class counterparts.
However, the standard Scrambler 400 can go head to head against a Predator 500 and the Scrambler 500 (and may even beat the performance of a Yamaha Grizzly) – although the differences may not be significant.
But, this speed is more powerful than its larger displacement counterparts due to the car’s lightweight with a powerful 2 stroke engine.
Naturally, more advanced riders won’t be satisfied with this speed and will seek ways to increase the top speed of the four-wheeler.
In this regard I’ve listed a few steps that are shared from Aaen Performance to assist you in achieving a better rate of speed for the Scrambler (should you choose to go for it):
How to make the Scrambler Race more valuable
An earlier article described the way Jimmy “The Greek” Anagnoustopolous and his Dyno team transformed a Polaris Scrambler 500 4×4 into a drag racing champion.
When you use Scrambler 400, you follow the same premise – which is to equip your vehicle with the stage-5 set-up with a 44-millimetre carburettor, which drastically increases its power output, and consequently speeds.
Five stages of this process gradually increase RPM, max torque, and maximum horsepower with each step. They focus on maximizing the efficiency of the cylinder instead of rapid power increases.
The RPM remains at standard levels to guarantee the reliability of the system and prevent problems with the crank. The best part is that you choose if you wish to exhaust every stage.
Torquer and Top-End Pipe
The first step in improving speed is to increase the powerband from the stock level. With no modifications, the standard 400 Scrambler power mill comes with an expansive powerband that has the highest output of 38 HP at 5,750 RPM.
Installing an oversized pipe increases its powerband, and also gives it an impressive bottom-end performance and a max performance of 43HP at 6,250 RPM.
A top-end pipe that delivers powerful midrange power but still delivers good bottom-end pull will increase your brute’s horsepower to 48 HP when you run it at 6,250 RPM.
Stage 1: Top-End Pipe, Boyesen RAD Valve & 38-mm TMX Carb
This 38mm TMX flat-slide carburettor increases the response of the throttle and boosts airflow, which eliminates the requirement to have an airbox vacuum increase. The Boyesen RAD valve increases the mid-range pull.
If both valves are paired with a top pipe, you can boost your vehicle’s maximum power up to 52.5 HP at 6,500 RPM.
Stage 2: Trail Porting
A performance exhaust that is connected to a 4×4 is probably the most popular option for owners to let the airflow out and increase the power output.
For more experienced, knowledgeable mechanics and owners porting the cylinder head will do the trick more effectively.
Porting enhances overall flow and alters the RPMs at which the engine will begin to pull the maximum power.
Be aware that various types of ports are available, including trail MX, trail dun, and drag just to mention some.
The type of port you choose is dependent on how aggressive or gentle you would like the changes to be and whether you’re looking to increase the top end or all-out power but at the expense of your middle or bottom end.
In any case, opting for trail porting with the top-of-the-line pipe Boyesen RDA valves, as well as the 38 TMX flat-slide carbs will boost your power to 57HP with 6,750 RPM.
It is possible to get whatever porting you desire or even combinations of ports like an MX-dune port or moderate drag port.
You can go as aggressive or gentle as you like with the changes you wish to implement in your quad, however, it is not recommended to do the latter.
Before you decide, keep in mind that the kind of exhaust pipe that you have determines the type of porting you select.
Simply put, you must make sure that the porting matches the pipe you have. It is not a good idea to utilize the drag port on a Professional Circuit Pipe (view on Amazon) or shearer pipe that has An MX Port.
In addition, mismatching of the ports and pipes results in the unpredictability of RPMs and power loss.
Stage 3 Modified Top-End Pipe V-Force Reeds and 42-mm TMX Carb Stage 3: Modified Top-End Pipe, VForce Reeds, 42-
If you have completed the initial two stages but aren’t satisfied with the performance of your Scrambler making sure you fit it with a complete mod kit is mandatory.
It’s basically a bumped-up version of the first stage of the entire procedure. It is comprised of the following elements:
- An altered top-end pipe
- Reed blocks from aftermarket improve the throttle’s responsiveness and improve the performance of engines (not to mention that they work well with big-bore cylinders, ported cylinders kits, and powerful race machines)
- A bigger flat-slide TMX carburettor
However, instead of trail porting, which has minimal or no effect on RPMs, these improvements are coupled with race porting.
This can boost power output to 7250 RPM and 61 HP. If you are able to do this, you’re skilled enough. In the event that you fail, you might need to hire the expertise of a professional race outfit.
Stage 4: 440 Big-Bore Kit and More Porting
Big bore kits typically give you the benefit of 10 HP. However, given the number of changes you’ve made in the past and the last stage, it could only boost your horsepower up to an impressive 63 HP.
However, on the plus side, this will lead to significant improvement in the torque of the powerband of your vehicle.
The bore is increased from 85 mm to 87 mm and is fitted with a custom Wiseco piston that is forged. The machined and ported cylinder as well as the head are also equipped with gaskets.
5. Stage: Improved Compression Ratio, Monster Reed Cage & 44-mm TMX Carb
The final step in improving the power output of your Scrambler is the following:
- Make sure you finish your big-bore kit race porting
- Your quad’s compression ratio should be increased to 14:1.
- Find the Monster Reed Cage
- Increase the size of the carb
- Find a high-end race pipe
Make it a point that when you boost the compression rate, don’t overdo it until it becomes unfavourable for the engine.
The negative effects caused by a miscalculated compression rate are excessive noise from combustion and wear on the engine.
If you take the fuel consumption limit into consideration The ideal proportion of compression for the Polaris Scrambler 400 would be 10:1, while the highest is 11:1. A ratio of 12:1 would be ideal for the big bore kit 440, but maybe a stretch for the engine of your vehicle. This last stage is capable of delivering 75 HP at 8000 RPM.
This helps hard acceleration and can translate into increased speed if performed right. Add 7 mph to your maximum speed of 70 mph is an approximate estimate after completing all of these steps.
It is important to note that these five stages were originally intended for racing machines and are generally done professionally by outfitters. If you plan to utilize your quad to race in drag races follow the steps (provided you’re prepared to invest at least $2,800).
If you’re just looking for your four-wheeler to be able to give you an aggressive feel, but without making a difference in the bottom pull and midrange and traction, the first two to three steps will suffice to turn your Scrambler into an elite speedster.
