I think this happens on the thunderbird 900 too when the battery is low. I know owners keep the battery fully charged.

Oh I’m shocked that triumph fallen to offer customer service

I have a 2013 Truxton - must be exactly the same thing - but hasn't failed yet Good luck with Triumph!

That's just terrible, mate. Thanks for posting. I was thinking of buying a T120 but I reckon I'll give it a miss now. All the best.

Thank you kindly, friend. Just brought up numerous reports of same issue. Now I know how keen Triumph are to address, help and behave as the only entity that could be errant in this situation, I will not be spending my finest Great British Pounds sterling with this manufacturer in the future. Fair enough, the Japanese seem keen to earn my business and dont have a record of treating customers this way. So be it.

I have exactly the same year and model, even same colours. I've had a flat battery once and a tired battery at the end of its servicable life, and the bike must have a failsafe as it just won't turn over.

So many negative comments about Triumph who had no obligation to repair this 7 year old bike under warrently. I can tell you what caused this, the safe starting system gets bypassed for some other starter problem - then crunch comes as it becomes possible to engage the starter on a running engine

This is what happens after 'fixing' the half turn starter problem,, clucth switch, side-stand switch and neutral switch get bypassed. Then it's overly easy to engage the starter with motror running and in gear, just hit the starter instead of the horn. You won't know until you restart. The 'fix' for the half turn issue is just misleading, the problem is within the ECU and not bad switches.

Just garbage.

I own a 2013 had zero problems I have put 45000 miles on it oil and tires is all I have done. Check the valves twice no changes to them still in specs.

Triumph should be ashamed of themselves for not taking responsibility and not helping you out , I'm sure they wouldn't like that to happen to them. Thank you Serge for bringing this engine design fault (which could happen at anytime to any other T100, so be ready) and poor customer service, to the public's attention.

Thank you for sharing

Interesting. 👍🏻

Do a Google search for a < Bonneville TTP safe start >. This is the only solution.

Sad for your loss, thanks for alerting people to this problem , I was considering buying one of these but your experience really put me off the brand.

There's a UA-cam video somewhere that points out that (in alphabetical order) BMW, Harley and Triumph have the worst repair records over the first few years of ownership. Disclaimer - I've owned five Harleys and the bikes gave me no problems. It was the quality of work done by Harley dealers that proved problematic.

Thank you for your videos on this - NO Triumphs for me any more !

Couldn’t you have used jb weld or had somebody tig weld it back together?

How do you fix this

So sorry to hear that the company wasn’t interested in at least helping you out with a set of engine cases. 😮 I could see the owner being responsible for the labor. But the company should be interested in what caused this failure !

I have a similar sound at times when starting, but get it started. I wonder if I need to take the bike apart and check this...

I'm sticking with the Japs.

Didn’t Triumph investigate surly such a big failure is a factory problem and you should be covered?

I don't mean to be picky but the starter drive gear your showing as the problem is on back to front? was this how it was when you took it apart?

i hope you moved on from this you dont seem to hear stories like this from BMW or the big 4 Japanese brands i have a T120 and within 4 weeks of having the bike i needed a new wiring loom this was covered by the warranty ,good luck

Sorry to hear that Serge , but seeing what happened to you Serge, anyone worried about that (including me) should install a TTP safe-start kit £85.Can still get them as of 23/5/23,fitting mine soon. I do like Triumph but shame on you with this story Triumph.

Thank you!!! I was looking at a used bike......your video saved me!

This was a failure on early bonnevilles. It didn't happen that often and only seemed to happen if the engine backfired while starting with the starter still engaged. Triumph in I believe around 2005 beefed up the casting. There are some out there that even with this update the problem could still happen. Back then triumph did help out with some of the out of warranty failures. There is an aftermarket kit/ plate that can be installed to beef up the area so this doesn't happen. I have also seen online that some have repaired the bike using the kit, it is called Safe Start. Hope this helps. I have a 2007 T100 and keep my fingers crossed when I start it hoping it doesn't backfire.

I have 40,000km on my 2010 T100 and so far I have no problems. None! It is stored well and been in the rain once thanks to the Aussie weather. However if the Australian marketed W800 was available at that time I would have jumped on. I’ve been involved in Japanese vehicles from a very young age and a mechanic for almost as long. Always a fan of Jap built anything.

before you give it away, a pproach a really good tig welder and see if they can reinstate/reinforce those parts of the engine cases and outer cover that have disintegrated.

This story is really sad and disappointing, because all l have heard about these engines is that they are bullet proof. This is obviously a lie, a con, and plan wishful thinking. But this so typical of the British bike industry through history. Machines were poorly designed, poorly made with worn out machine tools etc, and the public had to accept it. If this was a BMW they would never have let this happen in the first place, and if they did inadvertently let some type of flaw like this get through, they would be embarrassed enough to fix it, because they have pride and integrity in their product. Not so the British obviously, and not so Triumph and John Bloor.

It also means that if it is a design flaw on your bike, that it could happen to others, that there should be a recall of the bikes to fix the flaw in all of that model engine.

There is aluminium welding technique. It's only for starting engine. But well, your bik, do what ever.

You can give PRO welder and he will weld aliuminium, no need discard all engine. This pars is only for starting engine and no affect on riding.

Micro Crack it's call in case

What’s a matter with Triumph factory ?

It initially sounded like a frozen Bendix. If only the problem/solution had been that simple. What a nightmare. I'll search for your follow-up video. No problems so far with my 2010 Bonneville SE.

I recently took out the shaft out the gear from the same part of my bike and it wont go back in all the way, any idea how to get it in? Any advice appreciated.

Maybe too many parts being contracted-out to the lowest bidder. Think I'd have sourced a salvage motor though.

First time I've heard of anything like this on a Hinkley Bonnie. They've always been ultra-reliable and 'safe' purchases to the point of being a bit bland to ride. Be interested in the follow-up.

I understand this is an old vid but 2 question, if you have time and you don't mind. What caused the failure in the first play Any Idea, would like to know as I"m looking at buying a used 2013 Bonneville t100, and the 2nd question is, what bike did you purchase to replace the Bonneville, Thank you Karl Squire

Could the bike still be started by push starting in second gear?

Hi Serge, just opened! my triumph up to take a look at mine and my outer casing has also broken but damaged my starter motor drive teeth ...would it be possible to communicate direct ? as my triumph is a 2003 Bonneville as this seems to be a flaw in a very strong engine cheers...Trevor

Triumph twin power sells the safestart that covers the idler gear boss. Cheap insurance for the engines Achilles heel

Tell me please , how this happened. I guess it was your mistake, or driving skills?

That sucks

Well done.

I only heard last week talking to a motorcycle shop owner in perth Wa he had sold a Triumph speedmaster not sure of the year and the same problem had happened being under used bike warranty they had to fix it, they eventually found another engine from somewhere in the eastern states, fitted it up, within a short period of time it had the same problem, the motorcycle shop managed to find someone that could weld the problem area properly, the shop lost a lot of money sorting out the problem, the bike shop did the right thing

Triumph know their transmission is flawed. They should put their hands in their pockets and fix it under warranty. A lot of potential customers will make other choices for their bikes.
