Win, on which basis? Okay, we’ll tell you more about the KTM 450 SX-F top speed details, specs, and review. Let’s find out together why it is suitable for you.

Sublime Engine:

Which is the most coveted thing by speed freaks? Yes, they crave unrivaled and unbeaten power. Something that the KTM 450 SX-F is known for. Its 4-stroke motor engine combines a single overhead camshaft with the latest electronic injection system. And guess what happens? It just makes the motorcycle beast in power.

Extremely Lightweight:

When you look at the KTM 450 SX-F, you will feel like this bike has gone through a crazy diet. The frame is so light that this bike is the lightest 450cc engine on the market. Despite the lightweight, there is no compromise when it comes to performance. It can deliver continuous power in every revolution range.

The slender profile of the bike makes it very easy to control as well. Tight cornering is very easy with this bike. Just make sure that you don’t fly to the moon with this one.

Perfect Balance:

The compact SOHC cylinder head mainly focuses on mass centralization, making the bike a topper in the balance course. Besides, the overall handling experience is excellent.

Great handling comes with great responsiveness. The overhead camshaft ensures the optimized friction surface and makes the valve responsive with timing.

Additionally, the crankshaft is located close to the center of gravity. The intelligent designer of KTM 450 SX-F follows this rule and utilizes a connecting rod for compact motor and power delivery.

This design not only enhances durability but also ensures less effort and cost. Durability, efficiency, and low cost, what a combo!! Isn’t it?

Tough Frame:

KTM 450 SX-F doesn’t compromise quality. The frame of this motorcycle is made with a hydro-formed chromium molybdenum frame. The same has been done with the rest framework to ensure consistent quality.

The mainframe has a full factory orange powder coating, and aluminum is the raw material of the subframe. This aluminum makes the body lightweight and provides a comfortable feeling to the rider by ensuring easy movement across the seat.

Efficient Wheels:

Efficiency is the main term when you’re going to measure the performance of your car. The Dunlop Geomax MX33 tire of the KTM 450 SX-F consumes less energy to move. Besides, they will help you with better bike suspension.

Furthermore, the Dunlop Geomax MX33 tire has in-built aluminum spoke that reduces the frequency and keeps the spoke tight. This will also give you a durable wheel that will last longer.

Brakes:

Good brakes can save your life, dream, and family’s happiness. KTM 450 SX-F cares about you and your life. Its highly effective braking system combines lightweight wavey discs to give high-level braking efficiency with less brake fade.

The bike comes with a rear brake with a 220 mm disc and a semi-floating front brake with a 260 mm disc. Furthermore, KTM added a polyamide composite protector for the front disc so that it can remain recurred for a long time.

Advanced Control for Traction:

You can’t race at high speed on slippery and wet roads. The traction control feature is just a big savior for you if you’re coming out in rough weather. It guarantees efficient power down and controls bad roads and temperature.

This advanced system will monitor your throttle input. Additionally, it will also check the RPM rate of the engine. So when the machine creates more RPM, you supposedly lose grip, which will be inefficient. To reduce that, the traction control will reduce the RPM and give you better control on the ground.

Launch Control:

Another great feature that this bike comes with is the launch control. Referred as an unfair advantage by many, the launch control will help you launch the bike at the highest efficiency level.

One awesome feature of launch control is the EFI control lamp. With its flash, the upper triple will let you know that it’s the time to get the elbow out, keeping your head down and focusing on the road.

You can activate the launch control easily by pressing both buttons on the map switch. This will efficiently launch the start gate and reduce the maximum speed for the ideal power to traction ratio.

KTM 450 SX-F Top Speed

Speed is the main game of this KTM 450 SX-F. The bike is built in such a way that it can satisfy all the needs of a speed lover. From the data of some riders of KTM 450 SX-F, the top speed of this bike is 123 mph (approx). Pretty good for the speed and race lover.

These data are gathered from doing a dyno test. The Dyno test gives an approximate result of the top speed, power, torque, and others. This is an inaccurate result as the test is not done On-road.

Do remember, a dyno test won’t justify a lot of aspects as compared to a road. A dyno will create the most positive environment for the bike to run at its optimum power. But the story can be different when it is running on the road. As roads are uneven, the speed will decrease significantly.

Besides, some other factors such as the weight of the rider and the wind direction will also affect the top speed of the bike. However, despite all those factors, this is still one of the fastest dirt bikes.

How to Increase KTM 450 SX-F Top Speed?

KTM 450 SX-F is the king in racing. There’s no complaint about the speed of this champ, but who doesn’t want more? Yes, you can increase the top speed of the KTM 450 SX-F by spending some money. It may cost some extra dollars but give you unlimited happiness on the road.

1. Ignition Mod

The engine is the game-changer for every bike. The four-stroke engine of the KTM 450 SX-F is already unstoppable. But you can make it unbeatable. Try Vortex ignition from Chad at XPR Motorsports or Jamie at Twisted Development and feel the change.

In the mod field, this modification is beyond imagination in the mod field for both 2 and 4 strokes. The modification will allow the engine to simply added some pulling power or Revolution Per Minute (RPM) response. There is more pulling power / RPM response, so there’s some extra speed guarantee. This modification has a 100% approval ratio on the 2021 KTM 450 SX-F.

2. Engine Mod

You already know how good the engine of the KTM 450 SX-F is. But with a single mod, you can make this beast into a freaking Godzilla! Twisted’s stage 1 is the number one recommendation from us. This engine package has CNC head porting and decking.

It opens the valve easily and allows a greater flow by re-shaping the valve seats. The final result is some extra speed on your bike.

Some engine packages reprogram the ECU. Reprogrammed stock ECU load up EFI maps according to your riding style. 

3. Weight Mod

Lighter speed means higher speed. Hence, the KTM 450 SX-F is so fast just because its so light. So, what we can do to make it even faster? Make it even lighter.

Flying machine factory or FMF systems cut some weight from your bike and increase the power. Less weight and more power help your bike generate some extra top speed.

But, you need to ensure that you’re putting the power to the floor/ground properly and efficiently. We believe that your modification won’t go in vain, and you’ll always ground the energy efficiently to generate extra speed.
