You guys are obviously all forgetting that they can also change the bore and stroke at KTM. A frame change is rookie shit.

I’m gonna go with your being sarcastic? Frame changes to get the geometry of the motorcycle is much more difficult than bore and stroke

I think it was a joke referring to when Davalos mentioned in an interview about the team changing the bore and stroke when he was on Team Tedder.

Yes it was a joke. Last year Tedder said with KTM they had ability to change the bore and stroke in an interview with RacerX

KTM wouldnt' likely be running around all season in the back of the top 10 with a GP frame. That wouldn't be worth risking an embarrassing protest over, because only production is legal. Everyone who has tested the new frames said the same thing, overly rigid. Team Austria has had a very rough year, and JA21 and DW15 have also struggled. Bam Bam had been the bright spot.
When’s the last time a Factory AMA bike was torn down for a compliance inspection?

It’s been stated several times that Roger put them on their GP Team package since they were delayed in their own MX testing due to SX championship contention. They were late to the game and thought they were better to start the 2021 National series with the GP package than what little time they had left to test to develop their own package.

I’m willing to bet Cooper finally convinced them to ditch the GP frame version and let him go back to whatever he was running at the end of SX. I could see this being a big deal to Roger and Ian because when the frames are different between USA and GP, the team loses correlation and data between the two teams. The frame change would also impact suspension settings, forward traction which would require diff ECU settings/mapping, and probably many other small things.

Anyone’s guess as to what’s different with the GP frame.
AMA rules say that the frame geometry needs to stay OEM.

They can ADD bracing, but cannot take any away.

The GP frame cannot be too far removed from OEM if that’s the case.

Exactly, he was feeling it today and said all that stiff to mess with his competition and the fans.

His bike looked much better at track anyways. If using 2018 softer frame and even swingarm from Husky that has same dimensions but its softer with more flex you could make totally different bike.
Cant wait to see what direction KTM goes with new 2023 model later this year.

I thought most geometry could be changed with triple clamps and swingarm length

Lots of changes can be made to the frame externally. Aka engine mounts subframe height, different bolts of TI vs aluminum or even stainless steal. All of that adds up to flex/rigidity
Plus as well, and correct me if I’m wrong, can’t gussets be added?

I thought rules said production frame with no material removed with no geometry changes but I thought you could add material? I could be wrong but the thought did occur. I remember it was a common thing on the steel frame smokers.

And on that note, and I’m purely speculating because I’m again thinking of common procedures in the “old days”, don’t factories also do things like a production floor frame and maybe just have a wider bead of weld in certain areas or using material in areas slightly thicker than stock?

I’m behind a little on modern chassis touches that fall within or skirt the race rules so figured if the topic is here, bring it up for discussion 👍

My first thought was they switched to the earlier less rigid frame. And I have to laugh when people scoff at the comment of changing bore and stroke. I’m not sure if it’s AMA legal, but bore and stroke can absolutely be changed to alter power characteristics within a given displacement. For example, assuming an identical total displacement … a longer stroke/smaller bore combo generally gives a more torquey and smoother power delivery. A shorter stroke/larger bore combo generally gives a quicker revving and harder hitting power characteristic. There’s many other factors that come in to play such as Rod length to stroke ratio, cam timing, etc. The bore and stroke is just part of the equation.

I am trying to think where I heard a comment about taking an SX bike/SX mentality into outdoors. Maybe it was Jeremy Albrecht on Whisky Throttle. The point being that the SX mindset was a poor starting point.

They will have added bracing. They have to run the homologated frame, they can't remove material (officially) but they can brace it with extra stuff.

Serious question here:

With the ability to run a frame that’s design is 5 years old (I thought it was 2 years but I’m an amateur) has any manufacturer tried designing SX and MX frames for production bikes every other few years?

For instance, if a frame was built ridgid good for tight point and shoot style SX racing, and the next generation frame was built with more flex that suited long rough MX style racing. If this was done race teams be able to use the different generation frames for multiple years in each discipline giving teams better ability to set up chassis.

Do you guys think that would benefit riders/teams in preseason testing and racing?
Just wondering if the rules only relate to welded parts of the frame. If so, maybe the frame design could be changed to have a bolt in/on section and the teams could change that section. E.g bolt in gussets that could be changed. Might be simpler.

The bike appeared to be more compliant. Hard to tell by watching if it suspension or frame related. Going off Webb's comments (if you can believe a sneaky Chihuahua) it would be an '18 frame or a current gen with less additionally rigidity built into it.

Whatever the case I am sure the hornets nest has been stirred.

Ofcorse they will run a factory frame if the rider wants it, no one will ever messure tube thickness or a degree here or there. the test riders in europe probably test 20 different frames a year.

When is the last time the AMA showed up at a race with a semi full of all the homologated parts from the last 5 years for every make to compare against at tech inspection?

Homo rule is a joke.

That sounds like the only 2 possibility’s as far a making a “Legal” frame change ? What else could they have done ? Think we’ll ever know what the change was ? If I was KTM I think saying “ We decided to just leave it stock without adding gussets” sounds better than “The 3 year old frame works better”. Curious to see how he does the last 2 rounds.

Maybe I am reading too much into it but for his bosses to kill him the '18 frame would be sure to raise a few eyebrows and possibly hurt sales.

His results are getting better because guys that were beating him earlier in the year are hurt and not racing. But go ahead and talk about the frame.

Webb being Webb. I think you guys underestimate him and his mental game. That is how he has fun.

If you put MM25 and AC back in the race he probably gets 5th. Make it not a hot day and Kenny beats him too. Plus, Sexton had an off day. Barcia out too.

Am I missing anyone? That could have easily been another 7th place finish. Granted he is riding better now though.

There would be some of that if he was running 10-15th and was now top 5, but he was around 5-7 and latched on to Dylan all second moto, definite improvement.
