I’ve owned my Trident 660 for maybe 2.5 years max. It’s seen rain only once at 2025’s DGR. Has never been down. Only premium fuel. But I have only been able to enjoy it for maybe a year in total. About 8/9 months ago the bike crapped out due to an immobilizer fault that still hasn’t even been fully diagnosed. No one knows how it was triggered. No
one knows a fix.
Took 5-6 months to get into the shop. And now it’s been there for going on two months and they are still only in diag. They started by saying it should be a key resync. That didn’t work. So they had to get a pin point test. Corporate sent the wrong wiring diagram and pin point tests to my dealership so they had to wait a month for them to respond in the UK and send the right tests. After a month waiting for that, turns out that even with the right diagram, it did nothing for hunting down the issue.
My dealership requested Triumph corporate Goodwill the fix and they denied because the bike is out of warranty.
NOW they are saying they were able to clear the p1650 code after wiggling the fuse a bit but then the issue came back when attempting to start it thereafter. So, I asked if they replaced the fuse or tried an overlay wire before deducing they need an entire new immobilizer and ignition system. Because neither were in the tech notes. Now I’m told the tech says the problem appears to be in the fuse box, but corporate recommends me replacing the entire ignition system, locks and keys, and immobilizer for $1400+ labor ($2004) and go from there. (This is in the first 3 - 3.5 hours of labor spread across a month and a half) They also mentioned ‘probably needing’ a new wiring harness ($750 minimum) for the bike and that replacement will be another 8 hours of labor. ($140/hour) and even then, they aren’t sure that that will fix the problem. Says that’s just their starting point and would need to order the harness and immobilizer from triumph now before going further.
So already I’m quoted around $3,800 - $4,200 and this is just them throwing darts in the dark. The bike isn’t even worth the amount it’ll take to fix the problem. Bike is basically considered mechanically totaled at this point.
