Single sided swing arm stand

I'm not sure if this topic has arisen, but I have an old single sided swing arm stand from my old Triumph 1050 Speed Triple. I was wondering if it would fit the 1290r ?

Yes.
It's the same size pin.

I use my Harris stand on both my Speed Triple R and Superduke 1290 R.

another side note, I had a single sided swingarm stand from Pitbull from 10 years ago from my Honda Hawk (NT650). called pitbull and got a new pin that just slips right in, and presto, stand fits the 1290 perfectly!

Might sell it and get their stand that has two different size pins so you can use it on the sprocket side for wheel changes, but also on the other side if you want to change the gearing or something.
