comparison between the sound of a kx450 and a kx450SR.

I just picked up this 2023 kx450SR to replace my 2021 kx450 for this upcoming race season. my 21 has the exact same upgraded exhaust that the SR comes stock with. and yet they sound different... its all about the head work 👌👊

I have a 23 450sr and it's one of the loudest 450's I've ever heard.

I felt euphoric just hearing this

Ones fresh packing…and pretty sure the sr pc pipe has different internals.

The SR has hand ported heads
