It does sound like having them lubed and adjusted at 23K was too late - they'd probably never been done before  :232:

So guess I'll investigate the cost of taper-roller bearings - sounds a better idea for this application.

Could it be a bad (cheap) batch of bearings?

Most likely lack of lub from the factory and I doubt many dealers do them at the required interval,
had my 1050 9yrs embarrassed to say never touched them in that time.

The bottom is a taper bearing as standard from the factory. And, in many years and many examples of Hinckley Triumph triples I've only ever needed to change a top roller bearing once.

Attending to even the slightest hint of play will is key - don't leave it or wait until notchiness is felt.

Ha, I wasn't going to say, I never touched them on my ST955 in 11 years & 60k miles. I did check they were smooth & no play each year before mot time. Not been changed on any of my other 4 trumpets either.

The standard bearing on the Sport is round balls on the bottom race - not taper.      Probably why they seem to get more issues.
I know that first-hand because I've just had mine partially apart to re-grease them, although they were well greased actually having been replaced under warranty at roughly 11k miles by a dealer.

Interesting. I understood Tiger1050 (Standard and Sport) to have taper roller bearings top and bottom as standard.

Happy to be corrected on this but I'd say your dealer fitted aftermarket items when they replaced them and used ball bearings for reasons I can't fathom. Perhaps had them on the shelf or the mechanic has some bias toward ball bearings over taper roller bearings.

As I say, happy to be corrected on this.

I've just had mine apart on my 2018 TS due to a slight speed wobble... They were a nad too tight from the factory so thought I'd regrease while I was at it.
Plenty of grease in there (8.5k miles) but did em anyway...
Can tell you they are DEFINITELY not taper rollers and are the standard ball & Cup type
Torqued back up as per factory spec and all perfect now 👍
