There’s a new service bulletin to update the shift star and clutch hub to the 2026 MY spec. Triumph clearly recognized the issues and were working on a fix…sure seems like the “warranty claim rejections” were the work of shoddy dealers rather than Triumph corporate.


Pick a good dealer that’s willing to actually work for your business and you may have a better experience🤔

They didn’t have a cure for the problem until the bulletin came out.  That isn’t the dealer’s fault.

Correct, but there’s a difference between a dealer outright denying warranty or good faith service, and saying “listen they’re working on a fix. They will absolutely take care of you when they have the solution, but it’s not available yet.”


There’s multiple examples of Triumph providing entire new engines for 450 buyers as a result of issues related to this new TSB, even when they didn’t have a solution yet.

Dealers don’t have the ability to approve or deny a warranty claim.  I can promise you that if a solution was provided at the time by Triumph, the dealer would have been happy to collect payment from the OEM to do the warranty work and keep their customer happy.  As a matter of fact, they are bound by their dealer agreement to perform warranty work once approved by the OEM.

Again, correct. But they have the ability to pursue the additional channels that a manufacturer offers for “good will service” rather than full warranty claim. This channel is how Triumph has replaced engines for end users, as well as took care of the issue that I had after 1 year of ownership on my 250.


The manufacturer seems to auto deny the warranty if it’s outside of the states scope of warranty, which is 30 days of ownership. If an end users dealer gives up at that point without pursuing that additionally available channel then they didn’t put in the work for the customer.


As I’ve said in a previous response before the TSB was a thing, I feel like Triumph corporate maybe needs to improve the warranty claim process. This could be accomplished by maybe auto-submitting denied warranty claims (as in outside of the stated terms of warranty) for good-will service rather than making the dealer do it themselves.

Interesting to note!!!    The 2026 TF450 changes......

new shift star

new clutch hub ( I assume simply more holes for better lubrication of the plates)

new clutch disk spring (i assume a bit stiffer but not certain)

new head stays ( they have large holes I assume to make them more flexy than the 2025 version)

Question to anyone...

Will the 2026 shift star and the 2026 clutch disk spring fit on the 2025 bike??

I’m sure they will, because it sounds like that’s what they’re doing to fix the bikes that are breaking.  It might be a recall, so you won’t have to pay for the parts or the labor.

I think they have a fix for it hitting false neutral. I race for a triumph team in Canada and my team mate has had issues with it popping out of gear. They were able to get a part from triumph for the shift mechanism and he hasn’t had an issue since. I raced the 450 as well without the new part and it didn’t hit neutral for me luckily but I stayed in one gear essentially both moto’s. But shifting a few times into the race I was lucky it didn’t do that to me. Great bike, lots of potential. I’m sure they will clean up the issues with these bikes. 

Talan you seem to maybe have  inside info

would you know if the new shift star and the new clutch disk spring from the 2026 TF450 fit on the 2025 TF450?

Thanks 

even if its a recall I will not trust a dealer to do my bike work and will actually buy the parts and do the work myself

even if I felt I could trust the dealer to do a good job they are over 2 hrs away

I really miss being able to goto the parts houses for my parts. Dont like the Triumph biz model

The post up above says they are using it to update to 26 specs per the service bulletin.

It’s just a matter of time until Rocky Mountain, Partzilla, or Motosport gets set up as a dealer.  As soon as they do, they will be able to sell parts online.

ha well im at around 3 months from surgery and I have been advised to stay off the bike. Usually I pay little attention to that BUT with a full rupture achilles I think I will do as Im told for a changeWink

That means wait till around 5-6 month mark but the snow will be fly so looks like wait till spring... Ug

As for the Honda/ Trumph compare....

 The stock Honda ergos get the nod but not by significant amount, AND the Honda seat is the worst  with about maybe 1 inch of foam between your ass and the frame rails SO ya need a thicker and stiffer foamed seat and that does mess the ergos up a bit. Ya dont need a lot ( I got the Guts seat at only 1/2 inch higher and that was enough) but now ya have a very tall bike and the Triumph ego then wins. I see they ahve addressed this on the 2027 Honda. Bout time

 Triumph is near identical in ergos and basic handling to the 2016-2022 KTMs BUT with out the harshness in the rear those ktms had with any reasonably stiff valving AND of course the KYB stuff is better than the WP stuff. The AL frame on the Triumph feels just a tad less lively than the steel on those KTMs. Not nessasarily a bad thing but it does feel a touch different.

In turns the stock Honda was amazing and often too good in a bad way as it oversteers if you load it up. And once ya get the valving stiffened up a bit it no longer turns as well as stock. Good stock for novice but not faster guys. 

The stock Triumph rides a bit front high and fights the turn on hard pack  dryer stuff BUT its so nutral and predictable that ya feel emediatly more confident on it over the Honda. I put a .48 coil in one fork on the Triumph (stock they are .5) However due to the injury Im dont know if that works well yet. I tryed low sag numbers oon the Triumph( 100mm) to balance out the front high feel However that isnt the best feel. It requires you to be more precise comming into turns. The lower center of gravity feel of running 103-105mm sag is usefully more forgiving and suprisingly more confidence on hard pack when on lean. Always suprising to me that just a couple mm change in bike ride height makes that much difference. 

I still have the Honda and not sure yet on it. I suspect some race cups or a different tripple clamp offset may be the ticket to a more confidence inspiering feel on that chassis and may try that next spring.

Its  hard to stay off the bikes. I feel great and its tempting to say the least BUT like I said this one isnt like a broken bone. Looong recovery no matter how hard ya PT. Tendon is "healed" BUT long time to get the fibers aligned ( no real durability till that happens) and nervious system firing back to normal( low strength till that happens). Interesting to note that the tendon doesnt really repair itself tha way we think. It scars over at the join BUT then it grows a bunch of new stuff around that and thats the stuff that gives the strength back. Ya end up with a big ugly looking wad compared to the other foot ha.

I'd wait the full 6 months with Achilles too. LCL while a ligament is kind of similar with all the tension, it was a hard rehab. I had my posterior tibial tendon re-anchored in my foot, that wasn't too bad.

I'm sold on the 23.5 offset on my 22 Honda. The forks were very digressive stock, so I gave them a much closer to a linear damping curve. They started softer and ended up much stiffer. I can't ride right now either due to my wrist. If you were back on the bike I'd let you try the 23.5 on your Honda, but by the time your riding I plan on riding too.

ha cant say I know about the Op BUT my Triumph with only 3 hours does not shift well  AND I found the large oil pump rotor( the one under the counter shaft sprocket) to be warped ( likley just a bad casting as its plastic) and sticking in its bore. I replaced it with a steel unit from a KTM. The reports that the plastic pump gears are an issue may be because the plastic pump rotor is dragging hard and putting a load on the plastic gears they cannot take?

I hope the 2026 Triumph shift star fits my 2025 and helps with the notchy shifting, however I have doubts. I suspect the new shift star addresses the false nutral issues BUT likley not the notchy shifting.

Someone mentioned a few months back that triumph put some tools together and bought a transit van for rc to drive around and replace the damaged parts on these. Backside of his contract.  Kind of a celebrity repair team. Maybe he is doing this since he is not at the races.  Anyone had him fix your bike yet? 

Pretty sure RCs favorite tool is a crescent wrench.

ha cant say I know about the Op BUT my Triumph with only 3 hours does not shift well  AND I found the large oil pump rotor( the one under the counter shaft sprocket) to be warped ( likley just a bad casting as its plastic) and sticking in its bore. I replaced it with a steel unit from a KTM. The reports that the plastic pump gears are an issue may be because the plastic pump rotor is dragging hard and putting a load on the plastic gears they cannot take?

I hope the 2026 Triumph shift star fits my 2025 and helps with the notchy shifting, however I have doubts. I suspect the new shift star addresses the false nutral issues BUT likley not the notchy shifting.

What a coincidence that the KTM part drops right in.

What I didn't know is that KTMs majority owner Bajaj is in bed with Triumph. They co-develop models together and then Bajaj builds them for the Indian market.

triumph street guys are having some issues at the moment as well if reddit is to be believed. issues getting parts and getting triumph to hold a dealer accountable wrt warranty process. 

im a triumph fan, but it will be interesting to see who does a better job of pissing off the american moto market first/more with their after-sale support between they and Ducati.

I was responding to a poster who was so desperate to ride his new bike, he was putting KTM oil pump parts in it. Are you saying Triumph still doesn't have you sorted out yet?

What I heard and saw from a very reputable engine tuner in the business is that the bike is exceptionally well built, in fact, one of the best in terms of engine construction, except for one major issue: the crankshaft is severely unbalanced. Everything else is top-notch, but the crank balance was so far off that it ranked among the worst, hence he had a lot of them to do.

This assessment isn’t based on a single example, but on data collected from multiple crankshaft balance jobs.

Sounds like the British engineering was on point, but the Thai assembly line has room for improvement.

Picked up a 2026 TF450X. Currently going over it with a fine tooth comb before I ride it. Bike seems very well built, rear shock is pretty annoying to remove cause the air box is just barely in the way of the upper mount bolt. 

I've already ordered the KTM oil pump rotor cause Ive heard the Triumph runs a plastic one thats molding can be iffy. Going to look into replacing it after my first break in ride once I'm done breaking it down and lubing the bike up. 

My biggest gripe so far is getting the service manuals and owners manuals, the lack of aftermarkets parts install instructions, like the wifi module. I just took a shot in the dark on the plug. Also some weird torx bolt location choices, I know most of the bolts are torx but some could have definitely benefited being normal hex head bolts. Like the bolt that tightens the steering stem is torx and I like to run mine very tight. 

Ill post updates here or the Triumph thread

There’s a new service bulletin to update the shift star and clutch hub to the 2026 MY spec. Triumph clearly recognized the issues and were working on a fix…sure seems like the “warranty claim rejections” were the work of shoddy dealers rather than Triumph corporate.


Pick a good dealer that’s willing to actually work for your business and you may have a better experience🤔

Educate yourself more on how the system works before placing blame 🤔.  Dealerships are notified immediately when a OEM roles out a recall or safety recall.  Parts/Service coordinate with the manufacturer to supply the recall parts and schedule times to get it replaced.  Go one star review some delivery driver

I’m referring to the claims of denied warranty service. That’s what this entire thread started on, as well as my original posts referred to.


Educate yourself more on the context of this thread…
