i want to start off by saying i have 0 issues with TA rear ends. TA ( trailing arm ) rear end designs are solid and have a lot of plus's. a arm rear ends offer more imo as well as multi link. the sxs 3 link designs are lacking in a lot of area's imo. in the Shock theropy (ST) video he mentions the rzr xp inhearant 4" toe in flaw. that is absolutely horrible and unacceptable imo. a team of engineers and that was the best they could come up with! how bad is the front end then?? i still cannot figure out why rzr put that toe link on the pro R !? it looks to be 22* or less and i cannot wrap my head around why that would be a good idea for toe adjustment! the sxs's are top heavy and roll easy, for that reason alone i personally believe the TA would be a better fit as they don't seem to want to go wider for stability. couple that with the wheel travel war they have going on, and the lack of suspension design, the TA is an even better choice. i really like that 2.0 engine rzr put out but the sxs is just sooooo ugly ( looks like japenese animae )as i find most of them. robby's design is far more appealing.
i saw that the new rzr has a claimed 24" of wheel travel and 16" of GC at ride height. as we all know, to have a usable 24" of wheel travel you will need 28" of GC at full droop. so does that mean the rzr is giving up 50% at ride height?? my guess is the rzr doesn't have a true 24" of wheel travel. if it did, it would be extremely top heavy at full droop as narrow as it would get at only 72" wide track width.
one thing that was stated by ST was that 18" of wheel travel is all one really needs, i agree. i disagree with his reasoning why he wouldn't choose a TA rear end as a team of engineers should easily be able to design the solution the telescoping cv/axle issue. now he didn't go into detail and i understand why. he is speaking to the mass's and they don't want to understand they just want to pick out the prettiest color.
robby stated in his video that 11" of travel, with a proper shock configuration, won a desert race, also that they went with 22" travel in there utv's. again , i agree , with a properly spec'd shock , this makes all the diff in the world. they are not cheap though and why he's running 4.0 shocks on speed utv's sxs's.
