mxtech1 Added a reply to Rev limiter?

7/21/2025 11:03am
He's doing this to create rear wheel inertia. The faster the rear wheel's spinning when he gets the wheel back to the ground means more acceleration after landing. For the engine, revving in the air is low torque, so the engine's going to spin up quickly and get onto the rev-limiter fast. The team understands from the data and engine's...
Go to https://results.promotocross.com/results/ then navigate to the "Main Event Results" then scroll down to "individual lap times" and "detailed lap times". Example above is for Hangtown. Forewarning....the method in which they publish this data looks pretty on the website, but it's extremely difficult to work with in data analytic software. Takes a bunch of formatting and cleansing to get a...

They're spending money to prevent the lawsuit costs from bodily injury, or even death from occurring, should the primary gear fail during use. If it was observed in test units, and a documented issue, that evidence would be brought to light during the discovery process and Kawasaki would then be negligent. They're only doing the stop sale and updating sold...

mxtech1 Added a reply to Deegan Tomac No Clutch Drills…

2/5/2025 9:39am
Traction control can't do it's thing if the rider is slipping the clutch as the ECU typically uses an algorithm that assumes the clutch is completely disengaged and transmitting full torque through the transmission. Clutchless drills allow the rider to build trust and confidence in the ECU settings and also provides the team with more data where the clutching variable...

I'd love to see the AMA implement a "spec" ECU & electronics hardware package to tighten the 250 class back up.

mxtech1 Added a reply to Hondas traction control wow

9/25/2024 9:04am
Honda certainly has something figured out in the way that they use the ECU to manage how the engine torque is applied to the rear wheel. It seems like no matter what surface they are racing on, the bike is always just driving forward in a controlled and predictable way. When you combine that with Jett’s unique ability to stay...

6/6/2024 8:09am
Did you read the article? It clearly states the patent space is in regards to how they are proposing to develop the powertrain used to couple the electric motor without having to develop a completely new from for an electric specific model. It's definitely different than what we've seen so far from Alta, STARK etc as they clearly designed a...

mxtech1 Added a reply to Rear holeshot device? What happened?

5/1/2024 1:44pm
Most teams figured out it was easier to leave the rear unlocked & manipulate forward bite through ECU tuning rather than having to deal with the unpredictably of the rear starting device releasing & allowing the shock to decompress at an inopportune time. The technology works better on road race bikes since the traction levels are super high & the...

mxtech1 Added a reply to Data Acquisition in Sx/Mx

4/29/2024 7:18am
The ECU doesn't store data, it has to be processed in real time & then wrote to a separate piece of hardware where it can be downloaded to a laptop after the race. The loggers are small enough that they are typically tucked away inside the bodywork of the bike which is why we don't typically see details of the...

blockhead17 Liked a reply to forum topic I bought a set of Fake Riding Gear..

There is something to what you are saying.. if this company can sell a set of gear at $40 and still make enough profit for it to be worthwhile, you can’t convince me that the legit stuff needs to be 10x more expensive..

stuckey301 Liked a forum topic Timing the Gate

4/17/2024 8:06am
After seeing Sexton’s incredible gate timing at the muddy San Francisco SX, it got me thinking… how random are the gate drops? “… at least 5 seconds, but not more than10 seconds,” according to the Rule Book. As a geek, I did some analysis over 100+ gates drop in 14 SX rounds in ‘23 and ‘24. Feel free to look at the data and the analysis. TL;DR: It’s pretty predictable; just dump the clutch at 5.42 seconds after the board goes sideways in the your next 450 main. summary analysis

mxtech1 Added a reply to Does Fantic/Manarelli make the YZs??

4/12/2024 9:13am
The manufacturer's relationship is known as a joint-venture or joint partnership. Its a strategic partnership between 3 companies that creates value streams for all parties involved. Motori Minarelli was 100% owned by Yamaha Motor Europe. They were brought into Yamaha's corporate structure in 2002. Minarelli was well known for their small displacement two-stroke engine manufacturing expertise. In 2021, Fantic took...

4/5/2024 12:22pm
Just saw this release on LinkedIn. I applaud Stark for taking the initiative & continuing to find innovative ways to ensure the bike is on a level playing field for whatever class the riders chooses. It's clear they are extremely passionate about their product and technology and are doing whatever they need to in order to comply with the governing...

mxtech1 Added a reply to Villopotos GP Loopout

3/25/2024 1:47pm
A rider of that caliber isn't going to pull in the clutch to get the front wheel down when he's expecting a normally robust system to make an automatic adjustment for him. There's a fractional second window where if the system doesn't do what it should, the bike will loop out, & that's what happened. In order for these systems...

Malfunction of the traction control system. Under normal circumstances, the ECU would make adjustments to the available torque being applied, which would induce rear wheel slip and bring the front end down. The rider is expected to keep the throttle wide open, however this time something in the system had an error & the rear wheel traction was not reduced...
