Sticking Speedo

Took it to the shop and they could not duplicate my problem. They checked all connections and reset it. Dealer said he thought there was a service bulletin in the Triumph service system for this problem. After 200 more miles it is OK for now.

Mine stuck for the first time on the weekend. Stayed at 0 km/hr for about 5 mins until I slowed to a stop and clicked neutral.

I will monitor to see if it goes again and if so - off to the dealer we go.

Had mine do it today. I have about 2500 miles on the bike so far, and it first stuck at around the 60 mark, then dropped down to 40, then back up to 60.

After a while (about 50 miles) it finally started drooping back down to zero, and after a full stop with key out, it was back to normal.

One thing I noticed (how could I not?) was that when it started doing this, I was in stop-and-go traffic in the middle of Orlando with the temperature hitting 100F!

I am seriously wondering if the problem is being caused by some overheated electronics. Once I was able to get out of Orlando and onto the open road, then run it for a while in some air, it finally came around and started acting properly.

I will be reporting this problem to my dealer, however.

the dealer replaced my speedometer last week, rode about 30 miles and it stuck at 60 again, I call a let them know, they are working on plan C. got about 500 miles on since the replacement and some times it sticks and some times it works normaly. I think the next move is to replace the ECU.

Took the bike into the shop today for them to fix the speedometer. Not sure what they are going to do, since this is the first time they have ever heard of the problem.

I was able to physically show them the problem last Saturday, so they know for a fact that there is a problem with it.

In my experience, it seems to only happen after the gauge has been sitting out in the sun on a hot day (this if Florida and getting towards summertime), so I figure it is an overheating problem of the gauge itself.

have your dealer check the gear position sensor and road speed sensor, we have had a few go faulty causing speedo issues.

i would recommend the gear speed sensor first as we have changed 3 of these

First response from the dealer yesterday was that the problem (according to Triumph USA in Georgia) is possibly being caused by loose connections/pins.

Fine... they can try that. I am not going to hold my breath on it though. I will keep the idea of the gear position and road speed sensors in mind, however.

My guess on that, if it were either of those sensors, is that it would be the road speed sensor, as it didn't seem to matter which gear I was in, or if the bike was even completely stopped and kill switch applied... the speedometer would be stuck at some value other than zero.

I am headed back to the dealer today to take the next step on the speedometer issue, which will be to look at the previously mentioned gear and road sensors.

It has been approx 800 miles since they swapped out the original speedometer, sometimes it works normally, other times it sticks at various speeds (mostly 60 and 10), sometimes it will reset when the bike is turned off and on, sometimes not. It is fairly annoying as it seems to fail only when I am in an area of 'high traffic enforcement' and have no idea how fast I am going. I am not so sure that a cop will accept my speedometer warrantee issue story. probably write me up extra for the BS story!
