Morning.

Are there any known issues with Triumphs having dodgy gearboxes or at least the gear change?

I've got a 2013 R with 6k on the clocks. I've done 2k since getting it in April and initially I thought it was me getting used to the bike but eventually I took it back to the dealer last week. They apparently stripped it down to find nothing wrong expect for a gammy linkage. They say two of their guys rode it without fault...

...but several times during my usual 20 mile ride I'll go to change up and the lever just won't move regardless of using the clutch or not. This is on the power, between 8 and 9k revs but not ragging it and backing off a little. Maybe I'm doing it wrong?!

I've never had an issue on other bikes I've owned or ridden so I'd like to think I know what I'm doing! smile

Cheeky bump..

Any thoughts? The dealer seems to want to avoid taking to me about it!

I own a 2012 STR and am a member on triumphrat.net and I am not aware of this issue. Certainly not a trait of the 2012, 2014 and 2018 STRs which I have ridden.

Do you live anywhere near Burton? Fancy trying a 2013!

Edit to add... I didn't have a problem on the RS demo I rode either.

First off, is it the same on the upshift whether you use the clutch or not?

I had a similar issue with a 14 Street Triple.
I figured out it was my technique, I'd gotten lazy and wasn't dropping my foot enough between up shifts to allow the selector drum to reset.
Worth mentioning in case you have the same issue. Like you I never had the issue on previous bikes so maybe the Street Triple gear lever has a little more play in it than 'normal'.

Morning. Yeah, it's the same regardless.

Makes sense. But I think I've been trying to be more deliberate with it. Hoping to get out on it later to go let a mate give me a second opinion so I'll see then. See what the weather does.

Cheers for the help so far.





bozzy.

I had the same with mine and it seems to be better now.

I’d noticed that it sometimes wouldn’t change up a gear when warm, it was fine cold. Clutches upshifts were fine too.

I’d recently fitted an adjustable clutch lever off a +13 plate STR, and I’d set the bite point up so the clutch would bite fairly soon when letting the lever out. Small hands you see. I tested gear selection afterwards, but only with the bike running in the back garden.

I was certain my new problem was caused because I’d adjusted the clutch lever so that it wasn’t disconnecting the clutch properly once the bike got warm, so I set the bite point up so that I had to let the clutch out much further than previously and that sorted out my problem. It’s not done it since.
