Dirtbike engine suzuki vs kawasaki

Let’s begin our discussion comparing Suzuki RMZ 250 vs. Kawasaki KX 250 with their engines. There is not much difference between these stunters as they come with a 249cc 4-stroke engine with liquid-cooled DOHC technology.

They also come with dual injector-type fuel injection systems with semi-dry-sump lubrication.  However, there is a slight difference between the two dirt bikes here, and that is the RMZ 250 features a primary Kickstarter with an automatic decompressor.

Whereas the KX 250 comes with an electric digital DC CDI ignition system. Therefore, for those who like to go the traditional way, the RMZ 250 is the better option, but if you don’t like the conventional Kickstarter, you should choose to go with the KX 250. But we are going to declare this round in favor of the KX 250.


Let’s talk about weight in this comparison of Suzuki RMZ 250 vs. Kawasaki KX 250. Again, both these bikes are almost identical in their dimensions, and their weight also matches closely. The KX 250 2021 only weighs about a few pounds more than the RMZ 250 2021. The difference is 4 pounds, so we think this is not much of a difference.

But still, when you are looking for some high-flying action, you will notice the RMX 250 is slightly better than the KX 250 because it weighs a few pounds lesser, but there is only a slightly noticeable difference between the two. So, this round goes to RMZ 250 but only by the slenderest of margins. And this bike also has an advantage because it has a bigger fuel tank than the KX 250.

Suspension and brakes

SUspension and brakes of dirt bikes

Next up on this comparison of Suzuki RMZ 250 vs. Kawasaki KX 250 is suspensions and brakes. And this is the area where these two bikes slightly differ from one another.

Suzuki’s front suspension on the RMZ 250 dirt bike is an inverted telescopic fork with adjustable damping and oil-damped coil spring. On the rear end, this bike features a single unit with an oil-damped coil spring and link-type damping force with adjustable spring preload. This type of setup is excellent when it comes to comfortable riding.

On the other hand, the KX 250 also features an inverted telescopic fork with rebound damping and adjustable compression on the font. While on the back end has a new unique track suspension system with adjustable compression damping and preload and rebound damping. This system contributes somewhat towards the overall weight of the bike, which enhances its comforting ride.

When we talk about the brakes, the RMZ 250 features simple disc brakes on both ends. The KX 250, on the other hand, comes with a semi-floating dual-piston petal disc brake and single-piston petal disc brake on the back end.

This configuration also adds some weight to the overall rig. But this round belongs to the KX 250 as it is much more superior in terms of performance. But when it comes to self-maintenance and repair, the RMX 250 is a much better option.


Ergonomics of suzuki and kawasaki dirtbikes

Let’s discuss ergonomics in this comparison of Suzuki RMZ 250 vs. Kawasaki KX 250. Both the machines come with almost identical designs and appearance. There is not much difference between the two, but there are still some.
