I assume you are talking about NO Boost?
Depends on the rider. My 06 Apex has right around 100lbs take off it. Fabcraft rear skid, Timbersled front end, All 4 float shocks. High ride seat, very light weight under tunnle exhaust, 7s battery, no parking brake, Etc.....
It does also have a 15 wide extreame on it which helps a bunch too.
700's no problem at all. 800's, depends on the sled and rider. Beat many 800's, but some of the 10's and 11's run very well right out of the box. Eric
