I'm a bit shocked too.
'99 Was a great year too as said. Sunn was doing its own thing. I had a 99 Xircuit Un. A very solid bike indeed. The flex suspension they used in some models was an interesting idea. Khs was using it too.
But the finish used in this Vertik instead of a paint job is very nice. In their manual they prefer chrome finish themselves.
I bruised my hand today in the icy roads of southern Finland. Luckily no damage to the Sunn
. Just my luck that we have had no snow the whole winter and now we get it when I finally started the biking season :/.
