Fox RP23 on a Scott Spark 20?

[Konaman]

I have a Scott Spark 20 - i think its a 2010 model.

Can i use a Fox RP23 rear shock on it, and what size travel should it be, if its possible?

The current nude shock is non functional

Please advise

I have had a bike with a rp23 shock (GT Idrive carbon) its a great shock on the downhills but I do prefer something I can totally lock out. I then got a spark 30 with the dt swiss shock not as good as the fox on the downhills but ok but I do prefer it as you can lock it out. I then got a Pina with a rock shock rt3 (very much the same as the rp23 fox not lock out) which I have now changed to a dt swiss lock out.

You get diffrent size RP23 . Measure the shock from Eye to eye and then go and find one .
