Inside the Pipe: September 1, 2026

Hunter Lawrence capped off a grueling outdoor motocross campaign by capturing his first career premier-class crown at the AMA Pro Motocross finale at Indiana's Ironman Raceway.

“More than joy and excitement, it’s honestly like a relief. Every race day, you can barely eat, your stomach cramps up, you feel crap. Saturday is the worst-feeling day of the week, and your body takes that stress over the year," says the Champ.

Racing his Honda HRC Progressive CRF450R Works Edition with steady grit, the Australian powerhouse navigated a chaotic, high-stakes final round—overcoming a first-moto crash to put together an 8-4 day that was more than enough to secure fourth overall and hold off his brother and teammate, Jett, by just two points in the championship standings.

"Initially after the race, it’s more of a sigh of relief, but this is a huge accolade that I think has validated my career. I’ve seen Jett get enough, so it’s nice to get one up on him. The guy’s freaking good, so to be able to come in with the red plate for the last round and contend for this, I think it’s pretty special."

Congratulations to the Champ and the Honda HRC Progressive team for an a historic 1-2 sweep to close out an unforgettable outdoor racing season.

Making Champion Mufflers for Hunter Lawrence

Ooops... we blew through our marketing budget this season—so to save a few bucks, the most logical solution isn't making a new exhaust. It's having one of our guys take an angle grinder to a custom 450 Supercross championship muffler and "magically" grind the graphics until it reads "450 Motocross Champion". After a quick shower of sparks, the final product is boxed up and rushed out to Ironman Raceway, proving that top-tier race engineering is nothing without a little budget-friendly shop wizardry. Congratulations to Hunter Lawrence and the Honda HRC Progressive team on this year's Pro Motocross championship!

 

Watch How We Made a Ninja ZX-6R Go Faster!

The crew over at Moto-1.com put our Yoshimura AT2 Exhaust through its paces during its latest product review on Kawasaki's Ninja ZX-6R In its evaluation, it took a close look at everything that makes the AT2 a standout, from its aggressive design and matte carbon fiber end cap to the tangible bumps in horsepower, torque, and weight savings. It is always neat to see a seasoned rider experiencing that unmistakable Yoshimura rumble firsthand, and we couldn't be prouder of the high marks our craftmanship earned on the road.

 

Inside Yoshimura USA | AT2 FULL Exhaust Installed onto Yamaha R9!

In a recent feature, 650ib took a field trip to the Yoshimura R&D headquarters for an insider tour before putting the high-performance AT2 Speed Series full exhaust through its paces on the Yamaha YZF-R9. This video also showcases a quick, wrench-friendly installation of the 49-state road-legal system—highlighting how it sheds five lbs off the R9's curb weight and boosts rear-wheel output to a tire-shredding 110+ horsepower. After carving through the curves, 650ib raved about the system’s factory-level fitment, its head-turning bronze patina after a few heat cycles, and a deep, throatier growl that delivers pure ear candy without turning your neighbors into sworn enemies.
