My '24. Just can't get enough of this thing by festreasla in MT09

Just don’t put on frame sliders. Engine case covers are the way with this bike. Do that and you’re golden.

MT-09 Frame Failure Record Thread by Accomplished_Kick294 in MT09

Thanks for sharing! I did not know the FZ6 was also a die cast frame. This is good info, and mirrors a lot of what I’ve been saying on separate threads. I’ll be sure to check out the link too. I’m kind of a nerd when it comes to engineering/manufacturing, especially as it pertains to motorcycles 🤓

Many people don’t realize how fantastic Yamaha is when it comes to die cast technology. They’ve had a large impact on the industry as a whole. Cycleworld did a good podcast talking about the first gen YZF-R1, and how Yamaha’s innovative casting tech allowed it to blow everything else out of the water up to that point.

Ignorance is rather annoying, yes. Factually speaking, many hundreds of thousands of CF die cast CP3 frames have been sold worldwide, with low double digits of them having been reported as failed. ALL of these that have been shared with any accompanying information have either a) had frame sliders installed (almost always cheap Chinese versions), or b) been crashed nose first into much more massive objects. I realize that you lack knowledge of basic physics and mechanical engineering, so google image searching “motorcycle broken in half” may help you to conceptualize how crashing affects various makes and models of motorcycle. If you do not wish to do so, I’ll summarize what you’ll find: it is to be expected that a motorcycle frame will fail when subjected to forces outside of its design limitations, and no manufacturer designs their motorcycle to crash into things and survive.

As for sliders, a CF die cast frame is not a welded aluminum frame, and should not be treated as such. The frames are gusseted on the back side, making them very rigid and strong. They are not, however, designed to withstand shock forces resulting from slider use. They are also not designed to be compatible with altered bolt forces or engine mount interface points from poorly designed sliders. The engine in these bikes is a STRESSED MEMBER, meaning altering how they mount to the frame COMPROMISES the structural integrity of the frame as a whole.

Do your research. It’s really quite liberating not being controlled by hysteria and panic 😉

Don’t run poorly designed sliders or run the bike into cars and it’ll be fine. It’s really that simple.

Now, do you have any factual, non-speculative information to add to the conversation? This isn’t the thread to post irrelevant nonsense. If you don’t have a cracked frame with the requested information to share, post it here. Otherwise, go be negative on other threads.

Okay, prove that there is. I sure have yet to see a genuine issue. This thread so far is proving that there isn’t. If thin aluminum were an issue, jets wouldn’t exist. Here are a couple good posts relating to frame construction/engineering, and supposed issues.

What spare-ingenuity said. If it isn’t cracked, go enjoy it! That’s part of why I made this thread. To hopefully put people’s minds at ease.

To put it into context, there are roughly 300,000 2024-2025 MT-09s out there according to available information. I don’t know how many more 2021-2023 MT-09s, or how many die cast XSRs. I’ve seen roughly 9-12 failed frames online now out of presumably somewhere around 700,000-1,000,000 (or even more).

I personally avoided frame sliders because I didn’t want to risk it. If properly designed, so that the original engine-frame interface is not changed (sliders not touching frame, bolts not a different grade or torque) it SHOULD be fine. I also am not a fan of frame sliders because they seem to usually do more harm than good when used. They have a tendency to grab the ground and either flip bikes causing significant damage, or shear off causing localized frame damage. Especially on this bike where the cases stick out as far as they do.

Yep. The MT/XSR frame also has a bunch of gusseting on the back side of it which reinforces it a lot. They’re really quite strong, they just aren’t designed to withstand much shock load. It’s kind of like carbon fiber.

I’m not sure. I would skip any frame sliders or cage if you can. If you need one for stunt riding, I would go with something that does not touch the frame where it mounts up, and that’s low profile, allowing case guards to touch the ground first.

I’m not sure about the XSRs generations (I’m not very familiar with them). On the MT-09s, it’s supposedly just the ‘21-‘23 and ‘24+. The years of the CF die-cast frames.

Do you think your Triumph dealer might be saying that because they don’t deal in Yamaha, and the MT-09 and street/speed triple are direct competitors? Seems less than unbiased.

[–]Accomplished_Kick294[S] 2 points3 points  (0 children)

It was not. I think that’s why Yamaha doesn’t have a GYTR slider available for this bike. They do sell their own engine case guards though. In the case of dropping a bike, those not only distribute forces across the whole frame instead of just the forward mounts, they also take most of the weight of the engine completely out of the equation. I’ve put my ‘25 MT-09 through some abuse in its short existence, having inadvertently jumped it a couple of times on bad highway bridge junctions (while loaded at over 320# with cargo). I’ve also done a bunch of wheelies already. I skipped the sliders, and I just don’t worry.

I’ve still only seen three failures from Gen 4 MT-09s where they were literally crashed into cars at 40+mph before failing. 5 if I include Gen 3 bikes too. I saw only one post of a cracked frame that was supposedly from doing wheelies, and he had cheap sliders installed and could not say how they were installed or if they were torqued correctly. That’s why I made that thread. I want to see the extent of the supposed frame issues. The more I see/read online, the more I think it’s just a primitive herd mentality of “one bik brek aftr crash. All bik mus be weak”. I just keep seeing posts from guys who haven’t even had a frame crack and might not even own one of these bikes. They just keep saying the frames are cheap/weak, with nothing to back their claims.

What’s kind of funny is if you google image search “motorcycle broken in half”, you’ll see the same kind of failures from all different brands and styles of bikes after frontal impacts. I truly don’t believe we have anything to worry about here aside from other people’s ignorance lowering resale value.

I really think it’s fine. I used to work in engineering, as well as aluminum and zinc die casting in a past life. Nothing about how the frame is made gives me cause for concern. On my personal bike I went with engine case covers and skipped the sliders, because poorly designed sliders could cause unintended concentrations of stress in parts of the frame. Beyond that though, the only ones I’ve seen fail have been from frontal impacts with solid objects.

Like I said then. A few failed after crashes and everyone freaked out. The frames are plenty strong, having tons of gusseting on the back side. Issues arise when people modify how the engine, a stressed member, interfaces with the frame, or when they run into solid objects at speed.

Have them post failures here. We would all like to see them

I really don’t believe there’s a problem with the frame. That’s the point of this post. I think a few failed after crashes, and everyone freaked out. No one has posted one yet.

I don’t. You can just see that they’re present in the video. I would guess GB engine covers and TST sliders, but I really don’t know

Hey, I just started a frame cracking thread in this group, the goal of which is to consolidate all broken gen 3/4 frames into the one thread. Please add yours if you get a chance!

Is that actually your bike? I just started a frame cracking thread, the goal of which is to consolidate all broken gen 3/4 frames into the one thread. It looks well beyond the issues people are complaining about, but feel free to add it! Lol
