HAVE YOU SEEN THE NEW MXA: THE SEPTEMBER ISSUE IS OUT NOW

HAVE YOU SEEN THE NEW MXA? A MOTOCROSS MAGAZINE FOR GUYS WHO LOVE BIKES

What’s in the newest issue of MXA? I issue of MXA is jam-pack full of stuff you need to know, including how to build a 44-horsepower KTM 150SX two-stroke, what powers the TM 112MX Supermini that makes it so different from other SuperMinis, the tech details on the 2022 Kawasaki and GasGas motocross models and, as pictured on the cover, MXA’s take on what a GasGas MC450F Factory Edition should look like!

The U.S. Air Force didn’t have to ask us twice if we would like to spend five days in Alabama learning how to fly a F-16. It took almost a year before the Pentagon agreed that we could be trusted, but once on the flight line we had an amazing time.

MXA’s Josh Mosiman resists the urge to wave as he makes a low-level pass straight down the runway in the “Fastest Thing MXA Ever Tested.”

Josh checks out his fellow wingmen from the 187th Fighter Wing, while wearing his Air Force-supplied orange MXA helmet. Plus, while MXA was in Alabama we went riding on General Randy Efferson’s private track and returned the favor when he we took Josh’s flight crew to Glen Helen for a race a couple weeks later.

Former Yamaha, Kawasaki, Yamaha, Kawasaki, Yamaha and Kawasaki factory rider Jimmy Weinert (and that isn’t a misprint because Jimmy jumped back and forth between the two factory teams several times), tells it like is is, was and evermore shall me. If you love honesty, you’ll love Jammin’ Jimmy.

We decided to build a GasGas Factory Edition, but unlike the typical KTM Factory Edition we vowed to not rely solely on KTM Power Parts accessories (like the KTM and Husky special editions do). Instead, we picked from the products that we trusted the most—and, in truth, some of them were from Power Parts.

We started with a brand-new 2021 GasGas MC 450F, which a friend handed over to us because he got injured and couldn’t ride his new bike. He told us that we could do whatever we wanted with it, and with the help of Coppersmith forks, MX-Tech shocks, Nacstar wheels, FCP head stays, Xtrig triple clamps, Twisted Development ECU, Hoosier tires, Nihilo accessories, ODI bars and grips, MotoSeat and DeCal Works, we built something very special.

We went back in time to check out Kyle Lewis’ 2002 Moto Triple X Honda CRF450. On this mildly modifed bike, Kyle finished the top five at an AMA National.

Puch (pronounced Pook) rose to fame when Harry Everts took their exotic, twin-carb, Puch MC250 to the 19575 250 World Championship, but before that Puch made some clean, well-designed dirt bikes—largely in 125cc and 175cc configurations. This 1973 Puch 125GS was also available as a 175 and sold for $850.

The fans think of Mitch Payton as an engine tuner, porting genius, pipe builder, race team owner and motocross powerhouse, but he has to finance his race team by running Pro Circuit on the weekdays. MXA sat down with Mitch to see how Pro Circuit weathered the Covid-19 storm and why it’s so hard to get a Pro Circuit pipe today. He answers all of our questions and, when you read the interview, you’ll learn a vast wealth of information about the motocross industry.

Guess what? Speaking of Mitch Payton, he build us a 44-horsepower KTM 150SX that holeshot every moto it was in at the 2021 World Two-Stroke Championship. It was fast, making 6 horsepower more than a KTM 125SX and 3 horses more than a KTM 150SX.

The lifeblood of the sport are the companies that make products to protect the riders or improve their bikes. Then, then they take the money they make and sponsor more teams and riders, which they hope will help them sell more products and sponsor more riders. O’Neal and Moto Tassinari have made this formula work for decades.

Unlike the basic SuperMini, which is just a big piston shoved into a 85cc platform, Italian boutique-brand TM builds a ground-up 112cc race bike. That means special 112cc engine cases, new cylinder, bigger crank and longer stroke. As amazing as it sounds, TM builds the TM 112 Junior for the American market only.

This was race one of the 2021 AMA 250 National Championship, and with the exception of Cameron McAdoo, being run over by Alex Martin (26), most of these riders have made up to this point without being sidelined by serious injury.

“Hit Parade” shows you aftermarket products you might need, while “Forgotten Tech” highlights the innovations of past generations—like Honda’s 1979 23-inch ill-fated front wheel experiment.

“Team Tested” is an abbreviated test of products that we thought people might like to see again. Plus, “Twisted Logic” is Jamie Ellis’ space to make sense of the life of an engine tuner and ECU magician.
