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…

2026 450 MX Recommended Chassis Lengths

I have been wanting to do this for quite sometime as chassis lengths are important to how your motorcycle reacts on the track. Sometimes we just go about our day, slap a different size sprocket on or cut our new chain a different length without hesitation. However, when you do that it can/does affect how…

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.

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…
