2021-2026 Arctic Cat Blast ZR / RIOT / M 4000 / 400 Performance Products & Parts | Speedwerx Inc.

Armed with an industry-first 65hp, 400cc single-cylinder EFI 2-stroke engine and a best-in-class power-to-weight ratio, the new Arctic Cat BLAST Series packs jaw-dropping features onto a new lightweight, mid-sized chassis. Available in ZR trail, LT sport utility, and M deep snow versions, there's a Blast model to suit a wide variety of riders. 

You know we can't leave well enough alone though- we'll be developing performance parts and accessories for this new model with the same quality, durability, and of course the Straight-Up USA Horsepower that has made us known as the Worldwide Leader in Arctic Cat Performance! We plan on offering a variety of go-fast parts including exhaust, clutching, and more, so stay tuned for further announcements on new products as the development continues...

The stock muffler on the new Arctic Cat Blast 4000 series machines is the same fitment as the current 2-cylinder models, so we put our Standard Lightweight and L2 Competition Series Mufflers on one to see what they would sound like with the 65hp, 400cc single-cylinder EFI 2-stroke engine. Much like the 6000 and 8000 models, you can add a more aggressive sound and remove a pretty good chunk of weight in a matter of minutes.
