Ya I wondered if the floats would be stiff, I weigh 185 so I could imagine I will find them super stiff. I did end up getting my nytro shocks revalved and it was night and day difference. But I won't be able to sink much money into this machine right away since they are pretty expensive, I would like it to ride amazing out of the box..

The floats aren't bad as far as stiffness, you can run them soft but then they don't handle any type of bump, too stiff and you feel everything. I had my floats everywhere from 50 psi up to 110psi and didn't like them anywhere. Jumping off mine on to my friends base ltx with coil front shocks the base model rode so much nicer and was way more predictable. Plush and any bump and had every bit of the same big bump capability as the floats. Early reviews of the procross cats a few years ago all said the same thing, the chassis responds much better to coil overs than it does floats

Viper does not lack power compared to a Nytro. Stock clutching can make it look that way though, buy a clutch kit or simply put in a green/white/green spring and a 2mm shim and you will outrun any stock Nytro. Hopefully Yamaha fixed the clutch issue for 2015.

Never really heard of the issues with the 2014? I know they weren't running the usual yamaha 8dn belt, is this what your referring to?

My viper in bone stock form with 20 miles would wax a complete stock nytro on take off, mid range and top end. Everyone is saying the viper is way under powered compared to the nytro, I have yet to see any proof of this, I've seen dyno numbers actually showing the viper to make more power than the nytro on the same dyno, but that's not the case with some, either way the procross chassis is an all around better package than the nytro chassis, whether or not one makes more or less power, the viper will flat out outperform a stock nytro

The stock clutching calibrations on some of the vipers were a bit out of sorts from factory, simple clutch kits completely cure that

That is why I was puzzled you said "Even if it lacks a bit of power compared to a nytro"

No, for most if not all of us the stock clutching had an inferior belt and not enough belt pressure with too quick an upshift. The fix, either a vendor clutch kit or put a shim under the primary clutch spring and put a 8DN belt on. Green/white/green spring and a 2mm shim with 8FP weights if you want to go all out, but the big change is the shim and the 8DN belt.

Figured it was easier to word it that way so there wasn't people jumping all over that topic again. I will say from what I've seen personally, the viper has every bit, if not more hp than a nytro

So basically the belt takes the blame for the lack of belt pressure and too quick up shift of the clutches..kinda explains why so many have all the belt dust

In all fairness the 8jp has less contact surface than a 8DN, not sure bout compound but I suspect it is softer on the 8jp but that I am not sure.

Seems to me the root of all this evil is the secondary is just wound a bit off from factory, opening up too quick, causing the belt to slip, causing rpm hunting and belt dust and power loss. I know everyone has their own theory on setup and that's fine, there's 101 ways to go about clutch setup, however a mountain/deep powder setup will never work for a trail rider/corner to corner mogul masher, same with asphalt racing

SR Viper RTX SE
My story is that I really had my heart set on an LTX SE in blue, but when I went to the dealer to look at them all they had left were an RTX and an XTX. Not wanting to wait any longer I decided to buy the RTX,since most of my riding is groomed trails with a little boondocking thrown in. I don't know how any of the other models ride, but all last winter I was amazed at how much snow I could go through on this sled compared to my old SXR. I never had any problem with hook up either, every time I would line up with someone it would just pick up the skis a few inches and go. It probably helps that I weigh around 250 lbs on that one. My clutching was right at 8900-9000 and toward the end of the riding year it was getting to 100 a lot quicker as the engine broke in. I will be doing the clutching changes that nos pro and stingray and others worked out before this season though as I was getting a lot of belt dust and am on my second belt. I will probably get my rear shocks revalved as well since they are a little stiff.
Bottom line for trail riding the RTX is a well balanced sled although you can't go wrong no matter which one you get. Especially with all these smart guys on here to help you get it sorted.

Very well said, I think the ltx or rtx or going to be equally great on and off trail sleds. Since 2012 til this past year the cat sleds were either the rtx length or the xtx length, and their short track sleds are prolly the fastest out of the box sleds, period. If it were me I wouldn't worry about the track as much as I would getting the color and suspension package you want and a good price. Rtx or ltx it doesn't matter, you'll love whatever you choose. If you're an 85% trail rider I'd stick to one of those two models. Guarantee an rtx would go through more snow than the 136" nytro and go through it much faster
