Triumph TF450 transmission updates.

Edited Date/Time 2/23/2026 6:21pm

So its now 8 people and 12 bikes in the midwest I know of that have had issues with their transmissions going out. Bikes hitting false netural from 2n - and 3rd-4th. seen personally 3 bikes now failed shift forks and drums. I know of 9 other bikes woth issues.

Not 1 of these bikes has over 14hrs on them. Triumph is rejecting all claims and denying even 2 guys with less than 5 hrs. Dealers dont know what to say but are completely OK with telling buyers to fuck off and pay. 

I was on the fence about getting a 250 and 450 next year after riding the 450 but after seeing this. It's an easy no. 2 of the media guys have told me there's a known issue and the dealers should take care of it but their not. Maybe Chief keefer want to chime in since he's done a bit of work with them.

Just figured I'd pass along this psa for anyone thinking of getting one.

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?

This is not good to hear. I have a TF450 with 15hrs in it now, it has always been hard to upshift but I don't get many false neutrals. Had alot of metal on my plug at the 10hr oil change and was a bit worried. Just did 15hr change and it was pretty much spotless. 

It really sucks if the dealers aren't covering this cos the bikes are awesome. Easily the best 450 I have owned.

Some guys in Belgium had the same issue. I was really interested to get one, but opted for the KTM instead. Maybe in a few years once the issue is solved..

Why should dealers be responsible? If Triumph won't stand behind it then bitch at them. The dealers just sell what the manufacturer makes, they aren't on the  hook for junk parts/design.

And the manufacturer has to determine what is the issue first.

It isn’t the dealer’s job to cover a manufacturing defect.  The dealer does the repair work after the OEM agrees to pay for the repair.  If the OEM isn’t paying, that’s who your beef is with.

With that many people, it would be pretty easy to file a class action in hopes they'll start fixing their stuff.  Good luck

When someone spends 24k in bikes with you and both take a shit in under 11 hours you might wanna do something for customer retention. As a mechanic and former service writer I would be telling the bosses not asking to fix it. We can deal with triumph later.

I'm from Italy and know people who had the same issue, myself included. I switched oil from Motul to Bardhal and shifting has been smooth since then, if it can be of any help. Nearly 90 hours and no other issue, loving my 250.

It sucks though that neither Triumph nor the dealer are helping. Luckily, my local dealer here in Italy has been super helpful.

So what you’re saying is it’s the Rotella causing the transmission issues?

It absolutely sucks that Triumph isn't covering the issue, but I don't know how you can expect the dealer to foot the bill for what is clearly a Triumph design failure.. A dealer generally makes 10-12% margin on a bike sold at MSRP. Judging by how many Triumph dealer's I have seen selling the 250 well below MSRP, I'd say the majority of the bikes sold were sold at a discount and many sold at invoice just to move them. Therefore, the dealership would most likely be losing money footing the bill for parts and labor. That isn't a recipe for success. Dealer's are business to make money, it's that simple. Yes, it is nice when they can do something for free to appease a customer, but that isn't what pays the bills.

Yeah sorry I actually ment to say manufacture not dealer. But the dealer is the customers first point of call so I guess they should be the ones pressuring triumph to do more. 

I'm hoping mine doesn't give me trouble, but if it does and it is a known problem and no one was willing to help I would be very disappointed. It would be in triumph and the dealers best interest to do as much as possible to help. Otherwise they could lose alot of potential customers very quickly.

Hey guys. I’ve also heard from a couple people through email that their TF-450s are going into neutral. If you can email me the exact problems and maybe I can see what’s up and possibly help. I can’t guarantee anything but I at least can try. Doesn’t hurt to at least give er’ a try. It’s not my job but happy to help if I can. You can email me through my website.

I have had my 2024 250 for a year now and initially had some shifting issues with a false neutral or missed alignment if the shift drum - thus major loading to the transmission. Problem solved with a YZ250F Shifter. The issue as I saw it was, the bend is wrong and the shifter might not fully engage the next gear as it hit the counter sprocket. I discovered this when I was testing different shift heights. Plus I really did not like the feel of the stock shifter!! The new shifter (IMO) corrected the not full engagement and the feel. No issues what so ever since the change.

Sounds like a cheap and easy recall if that’s all it takes to solve the problem.

I went to a yz shifter on my 450 and although it did put the shifter in a slightly better position it is still very stiff to shift 2nd to 3rd and 3rd to 4th. Funny thing is it goes down gears a little too easy, even the slightest tap of the lever and it will down shift, sometimes even when not meaning to.

Dealers are representatives of the manufacturers. If I bought a brand new bike that had a transmission failure before its first “manufacture recommend” oil change you bet you butt I’d be throwing a fit at the dealership where I purchased the bike. It’s the manufacturer’s responsibility to provide the parts to fix, and the dealership’s responsibility to fix the bike and take care of the customer. 

If dealerships don’t want to take responsibility for the items they sell, then the manufacturers should sell direct to consumers. It’s called customer service, a thing that rarely exists anymore.

Unfortunately the class action may be not being able to sell the bike. There are quite a few at dealers here in N. TX that have been sitting. I want Triumph to succeed so I hope they address the issue. Lower than expected sales will be worse than anything else if they don't step up.

I have not bought a new dirt bike since 99, I thought all of them was purchased as is, no warranty on competition bikes. Has that changed?

KTM has been pretty good at standing behind abnormal failures that were obvious craftsmanship/material failures. I had a friend snap the frame at the head tube on a 2019 250sx with 80 something hours on it and KTM paid for the frame. He was dead honest about the time put on the bike and KTM stood behind it. They haven’t been perfect with it, but they’ve done better than the Japanese manufacturers in this department IMO.

Your dreaming, think of the financial burden that the dealer would take, and indirectly pass back to you anyway.
