Speed Twin Gone A Bit Wrong...

Sounds like you’ve got some water in an electrical connection possibly, have you used a pressure washer on it recently? You’ll still be under warranty won’t you, let a dealer sort it.

 

Battery ok?

 

You sure its not a Guzzi in disguise

That was the favourite trick on my Breva 1100 with its dodgy dash.

But as said above either water or battery or shitty connector.

 

I agree with Yorkshireman, get it into the dealers....

 

Low voltage or bad ground (earth) can cause havoc. Unless it's a Lucas dash.

 

I, like a few others I guess, would be interested in what the problem is if you wouldn’t mind updating when they’ve had a look at it. Best of luck.

 

This stuff is like a magic spray and has solved more than one electronics problem on my car and bike;

Recently had a leaking windscreen on my car that made the dash electronics go bonkers, also had a problem with the indicator on my bike. This spray fixed both, obviously may be something else causing your problems, but it is such an easy job to spray this and wipeup any residual I thought it worth mentioning.

 

yep any contact cleaner will work for connections, but on a newish bike guess it probably needs investigation by dealer!! Would be horrified if it was corroded connection?

But we are all curious as to the cause? so please let us know

 

The original tyre profile is quite tall so if your new tyre is a more standard profile it will be a smaller radius so could well be the problem as its now turning faster and triggering the TCT.

 

I would say that is most likely his problem. I have the suspicion that he got the wrong tyre dimension. Anyway, I consider that much more likely than an electrical defect. A much better choice would have been the Bridgestone BATTLAX T31, with the dimensions:

• Rear tyre: 160/60 R 17 69W
• Front tyre: 120/70 R 17 58W

When I had my 1200 bonnie it did all the same faults. Bulldog triumph had it back nearly two weeks and it turned out to be the traction control sensor aswel. It had a loose connection.

Hold on a minute, Triumph techs have checked the bike and say it needs £300+ of parts but all it needed according to a non Triumph qualified tyre fitter was a spacer fitting on the wheel sensor? If it isn’t covered by warranty because of a fault caused by a tyre fitter then I’d be tempted to ask Triumph for proof the work needs doing then “inviting” the tyre shop to cough up for their error. They’ll have insurance to cover that kind of issue, I wouldn’t be paying Triumph’s bill for something I’d not caused.

Funny old world. Yes if the tyre fitters lost a spacer while working on you bike. Triumph won't take the time to strip it all unless you volunteer to pay. And if the do strip it all and find the sensor damaged then that gets added on. As I think your warranty won't cover damage caused by a tyre fitter. As yorkshireman said you would have to pay and reclaim from the fitter. And no we don't need all this garbage they put on our machines one bit. My 2018 bonnie has stay in the one position since I bought it. I can't be arsed wit fiddling around with all these buttons and digits. I have rode bike all my life and don't need some Euro Prat telling me my bike needs this and that. Rant over.

Hi guys; just picked up this old blog from 2019 after taking my wheels off for new tyres after mot failure on my Speed Twin.

Used my old adjustable paddock stands to get both wheels off the ground. I tried to located the rear one with the universal cups but noticed it was fouling a small black cable that goes into the brake Caliper, & stopped straight away, thinking nothing of it.

Made some bits to locate properly & safely, then removed both wheels no probs. My tyre fitters fitted my free issue Pirelli Diablo Rosso!!! Tyres that I was replacing. Job done; with the normal bit of a faff getting the Calipers & pads lined up & all back on, for the formality of the Retest.

Start the bike up no probs, revving like normal !! Set off up the road & immediately a stuttering limp mode kicked in & tc lights flashing !!! 10/15 mph max, so turned straight round to figure out whatsup.

First thing I thought was to top up the brake fluid reservoir, even tho I didn’t think any had leaked out. Next I turned off the TC as I don’t have photographic memory of the handbook of which warning light is what ! or what buttons I should be pressing ?

I’m all in favour of safety gadgets guys but, I’m experienced enough to know if I whack open the throttle with those horses ready & waiting on wet roads; I’m on my ass !!

All I’m saying is more electronics & fly by wire; & more stuff to go wrong ??

Those 2 things I thought may be the cause, but the moment I set off again it went to limp mode again, but found pulling the clutch in & waiting for the revs to get to 3k ish I managed to coax it to the test station & maybe clear itself !!! No it didn’t & that’s what caused me to ask Google’s advise & got this forum & so opening up a can of worms, so to speak & joined the clan.

I have my thoughts that I may have slightly squashed the cable to the rear Caliper that sends all the clever stuff to the on board computer - 1st concern

• Not a lot of faith in dealerships that charge by the hour, & not to blame if 10miles down the road it happens again.
• Vagueness of error codes & swapping stuff that may be perfectly ok ??

This is the great mystery of Biking guys, & have read most of the varied comments you’ve offered Wurzel Chris; all worthwhile & valid !!

I just want to get it sorted as cheaply & quickly as poss & get back to riding this fabulous British bike.

I’ll keep you posted on what I find & happy riding Guys.
