Suzuki T500K tapered head stock bearings
Has anyone managed to actually fit a set of these without using a machine shop to modify the stem ? I've had two sets now and neither fit - one of the inners is too big and one too small - they should be both the same size -doing my head in now !!!

Think of how stupid the average person is, then realise that half of them are more stupid than that.

Re: Suzuki T500K tapered head stock bearings
The steering stem on the T500 & GT500 are different.
Haven’t confirmed it, but its my understanding that the All-Balls kit for the T500 is incorrect & the kit for the Kawasaki H1 works.
Recently did the upgrade on the GT550 cafe build. Used the kit lower bearing but used a different upper bearing that is thinner.
I needed to do the steering stem mod per the All-Balls instructions. You don’t need to have a machine shop do the work. The existing machined surface is sufficient to position the upper bearing. The bearing just needs to slide down a little further. A grinder can be used if one is careful to leave the machined bearing surface intact. I had a local bike shop do the grinding.

Thanks guys - put the original ball races back in the end - what annoys me more than anything though is the manufacturers stating that these fit the T500K when they are clearly not going to

I bought a set from Crooks when I was restoring my T500M. Fitted straight in with no mods required.malky wrote:Thanks guys - put the original ball races back in the end - what annoys me more than anything though is the manufacturers stating that these fit the T500K when they are clearly not going to

All the head bearings I've done, the inner race of the lower bearing is a little larger in diameter.
This is to allow the bearing to slide down to the bottom of the stem, where there is a slightly larger diameter shoulder to suit the larger inner race diameter.

Re: Suzuki T500K tapered head stock bearings
The two sets I had were nowhere near - the bottom inner fell down the stem and was like a cock in a sock and the top inner would not even go over the threaded part - total waste of time it's bloody annoying that the manufacturers list them as fitting a model when they obviously don't !
