R80ST vs R80GS rear shock fit

is the rear drive on the ST the same as the G/S? I was looking at wilbers shock and springs for the ST, and asked them about the G/S shock to raise the rear a bit.
They didnt seem to know if they were, and were reluctant to say it would work.

The BMW parts fiche shows the g/s and the st with different shocks, which probably isn't surprising. Works performance shows that the ST shock is 12.75 inches long and list two g/s shocks one at 13" and one at 13.31". I'm guessing if you increased the st shock by 1/2" you'd be OK. There are other factors to consider, front end height etc. JT

When we were looking at bikes for the wife, one offering was a g/s that had been lowered by using a st shock. At least that what the seller said.

The ST and the G/S are essentially the same bike but with some small differences.

The G/S rear shock should fit and work perfectly on you ST.

Many people convert STs to G/S, and mostly you only need forks and a Shock.

I also have an ST!

The rear ends are exactly the same except for the length of the shock. I don't know what effect raising the rear would have on steering geometry, but that's the only effect I can see from installing the G/S shock.

Thanks for the help guys, I may just go with the stock shock, to avoid any handling problems.
