From a statistical perspective, 20-min long main events are long enough that it allows the field to sort itself out in a similar fashion each race. The cream rises to the top….. When you look at lap pass charts from recent years, MOST, not all but most, of the passing is done by the 12th minute of the main. From minute 12 to 20, there is a significant reduction in the number of passes from the front of the field to the back of the field. Most guys are just coasting in the last few minutes trying to hold their...

With ignition retard you can really tame a 450, making it very easy to ride. Just hop on your phone and play with, oh wait it's a Honda... If only they had the technology of a Suzuki.

Data in MX often does not translate to what the rider feels, and how the bike rides. A good example of this was when Yamaha started switching over from steel frames to aluminum frames manufactured from castings and forgings that were then welded and CNC machined. The design engineers had enough on their plate with the manufacturing issues, they they designed the new bikes with the exact same kinematic geometry, and the frame design was tweaked to match the stiffness and elastic characteristics of the prior bikes. They did lots of FEA analysis, and load testing on prototype frames till...

I'm a mechanical engineer currently working on a personal project just like this. I've done a lot of testing on street bikes where the rider remains mostly stationary to the bike and the road surface is smooth and uniform. In those cases you can make good sense of logged data with just some on-board video to help with context. Motocross is difficult because of the rider-active nature, large movements of the rider's c.g. and large variances in forces on the handlebars and footpegs. To make sense of logged data you need to have lots of video and lots of measurements...

One of the challenges in collecting data is deciding what to do with it. In road racing there are less dimensions to analyze with a flat surface and traction conditions that are bounded. MX/SX tracks have changing track conditions both on different areas of the track and over time. Do you want to steer or track with the rear wheel? Can you infer the optimum tire pressure by understanding g forces, lean, and power transmitted? Or does your data tell you the obvious and 12 psi is about the same as 12.5? Tough to say but you can’t find out...

By example, when LITPro first became a big deal, they had a staff member or two go to the races and help track the data, store it, do reports, and display it for the teams. When it came down to the teams paying for their services, only KTM really kept their guys around...and that only lasted another year or two.

If i was "broke", this is the last thing i would consider doing. But hey, that's just me. I work way too hard for the toys sitting in my garage.

Most of the indoor stadiums are also nfl stadiums and you never know which ones will be needed and when in January.

It’s weird because the Yamaha shares the same chassis for 250 and 450 but he looks tiny on that thing now. Must be the different riding style between the two bikes that makes him look smaller.

Does it have more to do with stadium availability and weather? The Cali rounds are all baseball stadiums and open roof plays nice with mild winters.

LLs is not for "regular Joes" and you should have figured that out when you could not get past the qualifiers. You don't have a "honest shot" but its NOT because of the former Pro riders, I cant figure out why people just want to get there, if you are going to race then race to win and if you cant then dont waste time and money trying to just get to LLs

5 years... That's what these fast guys are complaining about... If you're an ex pro, racing +25 shouldn't be an issue.. If it is, because you have to race guys like Durham, then you know exactly how the other side of the fence feels..

That’s my point. A “regular Joe” is likely not in the fastest 40 in the nation. The opportunity to go is earned. Race 30+ now that former pros cannot race? Why not the 35+ in prior years? I get it you want to go and if you think I’m not being understanding, I am also not fast enough to go and never was. It’s not the former pros that are the issue.
