Tusk Moto Toolbox With Tools

By Seiji Ishii For decades, my system for going to the track or trailhead was pretty simple. On Friday, I'd walk into my shop, grab the tools I thought I might need, throw them into a toolbox, and head out for the weekend. It never really worked. By Sunday afternoon, the toolbox was a disorganized pile of tools.…

The Fitness You Lose Isn’t the Fitness You Think

By Seiji Ishii One of the most common conversations I have with riders starts about ten minutes into their first ride back after some time off. "I lost everything." Usually, they haven't. One of the most common mistakes I see is riders confusing a loss of sharpness with a loss of fitness. The two are…

The Myth of Greatness

By Seiji Ishii Ken Roczen admitting he battles severe anxiety may have helped more riders than his winning the championship. Fresh off winning his first AMA Supercross Championship, Ken Roczen stood on stage emotionally drained. Not hyped up. Not pretending to be untouchable. Not giving a polished speech about confidence and momentum. He looked exhausted, and honestly,…

Data Isn’t the Driver. You Are.

By Seiji Ishii Self-monitoring tools can help you train better—or they can stall you out. The difference is how you react to what they tell you. The Device Isn’t the Problem It seems like everyone is running something now—Whoop, Garmin, HRV, sleep scores, diet tracking. None of that is the issue. If anything, it’s useful. You’ve got…

The Day is a Terrible Scoreboard

By: Seiji Ishii I’m dealing with this right now. I pushed through the weekend because I wanted to feel like I gave everything I had, and now I’m sitting here sick. That wasn’t bad luck. That was the cost. If you use the day as your scoreboard, you’ll make bad decisions. You’ll take a session that was supposed…

Coach’s Cut: Discipline vs. Desire

Written By: Seiji Ishii Why training based on how you feel can quietly wreck your riding. The disciplined rider does not train based on desire. They train based on condition. That sounds straightforward until you look at how training decisions actually get made during the week. It’s easy to blur the line between what sounds good that…

Alpinestars Tech-Air Off-Road Review

Tested By: Seiji Ishii If you ride dirt bikes long enough, you’re going to crash. Whether it’s a front-end washout, a swap gone wrong, or a simple tip-over on a trail, it happens. What you’re wearing when it does is the only part you control. Airbag protection has been used in road racing and rally for…

Coach’s Cut: It’s Not the Bike

Written By Seiji Ishii Riders love bike upgrades. That’s probably why you’re here. You got a part in the mail, and you’re fired up. Surely this throttle tube is the key. As you shove a Totino’s pizza pocket down your gullet and wash it down with a Coke, you head straight to the garage to install…

Coach’s Cut: You Got “Strong.” But Did You Get Faster?

Stacking more plates every week only builds one lane of performance — and motocross doesn’t live in one lane. By Seiji Ishii Just lifting weights and trying to lift more all the time isn’t the whole picture. That’s just force development. The other lanes are tissue tolerance, power (speed of force development), and durability (submaximal contractions over…

Coach’s Cut: The Two-Lap Lie/How Early Speed Steals Your Best Moto

The Two-Lap Lie: How Early Speed Steals Your Best Moto By Seiji Ishii Two good laps can be the worst thing that happens to your pacing. You know the moment. You roll out, and the track feels good. Fresh enough to be forgiving. Your timing clicks. The bike feels planted. You hit two clean laps, and your brain…
