2019 marks a major milestone for the Kawasaki brand to own the 450cc motocross class.

As it turns out, the new big-bore green bike looks like a strong contender, especially when paired with Yoshimura's performance.

At Yoshimura, we saw an opportunity to make the new green offering live up to its potential.

Horsepower and torque have increased across the range for both corners with the new KX!

Maximum HP has increased by a staggering 1.7% and maximum torque has increased by 2%.

At the heart of the power is our RS-4 muffler with its Duplex Poly-resonant front chamber and the added overall volume helps bring the KX450F to life.

Pentagonal shaped sleeve

The front muffler cap functions as a poly-resonant chamber which helps reduce noise

Two-stage stepped baffle

Carbon fiber caseback

Stainless exhaust terminal

Repack kits, optional inserts and spark arrestors are available for all models

Proudly made in the USA!
