Jay, thats not the case with mine I am afraid, I have crossed that bridge. The dealer suggested this, but when I had the bike recovered to the dealership by the RAC, this was investigated. I can pull the lever all the way back to the handlebars, with the lever set on max setting, and the problem is still there. It is definately some part of the gear selector mechanism coming 'disengaged' in one way or another. There is a post about Street Triples doing it, although this was after extended use.

I have even recreated the symptoms on the centre stand, working my way up and down the gearbox with the engine running. It only does it on the way down through the gears, not up, and between 3-2-1. The lower the gear, the worse it is. Sometimes, getting it into first when stationary is a nightmare. Especially if you have traffic behind you. I've tried 'doubling' the clutch, blipping the throttle between gears, nothing seems to help, and I have even taken my feet away from the lever and footrest to ensure my foot is not stopping the pedal returning to it's normal resting position, so I am convinced it is not me causing it.

If you could investigate yours and get back to me with what you find that would be good, you never know, there may be a recall situation here like there was with the street triples mentioned on another post on here for similar issues! I hope not, I waited months for this bike!

none of them shift very good untill they get a few 1000 miles on them .Allso your clutch will wear in alot the first few 1000s miles allso.Allso they come new with light oil in them once they change it it will be alittle better .You may well have other troubles but they do get alot better with time.If they dont find anything just take the bike and ride it like you stold it it will get better.

I must admit I have considered the oil viscosity, so I will wait till after the first service, and try it again. It has now done 500 miles, and the service is booked for Saturday.

After they have changed the oil and filter, I will take it for another blat up the dual carriageway, and see if it has improved.

I may be wrong here, but I don't think this has anything to do with running in. The gear change mechanism seems to come unattached from whatever it connects with in the gearbox. I suspect something is not right.

And I will take your advice and ride it like I stole it. lol

We shall see!

As long as it will shift nothing can come unattached as such. As mike said they do take a while to bed and the runin oil is just that. Once you get an oil change at the first service things will improve, a synthetic certainly helps. In all honesty it takes a lot of Kms to fully knife through butter. Adjustment is the big issue, mnine came set up not to flash and the cable will stretch in the initial stages. Lever coming all the way back means little.
Slacken of the adjuster (handlebars) then adjust on the clutch arm till there is the smallest perceptible amount of movement. Then adjust the Handlebar to the 2 mm. Also check that your chain is not overly tight.
Hope it pans out well

Thats just the problem, it doesn't always shift. You press the pedal, and there is a 'clicking' sensation and the pedal goes looser (although the return spring still works) and it takes multiple presses on the pedal before the mechanism 'clicks' again and engages, enabling it to change gear.

i.e whatever mechanism the gear change shaft is directly/indirectly connected with, slips.

Imagine hanging off a cliff with your fingertips, and then your fingertips slip off the edge.....that sorta thing lol

Update: The Thruxton has been kept in by the Dealer. The Mechanic experienced the symptoms, changed a spring, I test rode it and it did it again. So she is in hospital for the time being.

Oh dear.....



No more fun for me this week.

Mine was doing that badly when less than 50 miles, but I have now put 90 miles on it the problem seems less. Talk to my tech..and was told once I change oil at 500 miles...the issue should go away.... Keep me updated.

Keep an eye on it.....accept nothing less than a perfect gear change. I have now got the Dealers demo Bonny, which has an identical gearbox. It is completely different, with good solid gear change. So I have proved 2 things. (1) it is not me, and (2) something is amiss!!!

The mechanic said it could be one of the components that turn the selector drum.

I thought I was going mad!

I will most certainly keep everybody updated.....information like this is invaluable.

I wish I had had things such as forums when I was younger back in the 80's....I had to work these things out for myself back in the day!
