Review of Kmod Gen 2 Rear Suspension

E

Evolution Powersports

Well-known member
Let me start by saying we have ridden quite a few sleds with various rear suspensions.

The first Kmod Gen 2 I rode was last November on a customers sled. It was early in the year so the trails to the play areas were ROUGH. I found that I could carry about 15 mph more speed through the whoops on the Kmod equipped sled. This particular sled has a BC 250 on it. The other sleds we had with us were 2 SC 300's and a BC 275. Compared to all of our sleds which would pick the skiis whenever the throttle was cracked, the Kmod stayed relatively flat and in control. When climbing, the Kmod stayed flat rather than "cat walk" up the hill. Cat walking can be fun, however, as the snow gets deeper and the hills get steeper, the front end needs to be in control and lower.

The next experience I had was in January at Island Park. We rode with Kevin, the owner of Kmod who has a BC 250 kit on his M1100T. Kevin out climbed both of our company sleds - a BC 275 and an SC 310 on with his BC 250. The only difference was the rear suspension. We spent the day discussing the reasons his sled performed so much better on the hills than ours, the better ride quality, shock package, suspension geometry and suspension adjustability. It was obvious to us that Kevin had pioneered elegant solutions to suspension design issues through countless hours of mountain testing. The biggest issue being that a good hill climb suspension will keep the front end down while climbing - the problem with this is it makes the front end heavy in all other conditions. The last thing an 1100T rider wants is a heavy front end when boondocking or trail riding. The Kmod can switch from hill climb mode to wheely mode in literally 5 seconds. On the trail on the way back to the town of Island Park, it was difficult to keep up with Kevin - I was bouncing around like a pogo stick while Kevin was sitting on his seat while going down the ROUGH trail.

We put a Kmod Gen 2 on my SC 320 sled right before we went to Alpine. We spent the week extreme riding with the Guys & Gals from Team Thunderstruck, Paul from Fire & Ice, Shaine from Twisted, and Kevin from Kmod. We encountered all conditions while there - concrete snow, mashed potatoes, 2' of powder, 6" on top of concrete, rough trail, etc. In every condition, the Kmod was superior. I had much more control while boondocking & climbing than the stock rear skid. We rode a few days where it was 24" of snow over ice. The stock rear suspension would wash out while carving in these conditions. The Kmod was more controllable and would recover easily. On the hill, it was no comparison.

We have been so impressed with the Gen 2 suspension and Kevin that we have partnered up with Kevin for a special Kmod Big Chute Edition rear suspension. This will be a complete skid setup specifically for guys with more than stock HP M1100T's. It will be a little different than than the Gen 2 as it will incorporate a special hill climb mode that will keep the skis even flatter than the current Gen 2.

We will have more information soon.

You mentioned the sidehilling a little, to me that was the huge factor, especially with big hp. The kmod makes it so easy to recover a wash out its amazing. Even on my stocker I threw the stock skid back under it and on the steep sidehills it takes a lot !! more effort to control it and keep it going. And with the kmod when you want to go somewhere, it just goes there, the terrain doesn't stop you its just a point and go where the stock suspension will grab ruts, bumps etc... and throw you around.
For anyone with a M110t I would recommend you get a hold of these guys, even if its stock.

There is way to have a balance on ski pressure, you can put stops in the rear to hold it back from pushing the front down and yet keep the skis down. Its all rider pref
 
You need to take a break...

Jim, you guys need to take a breather from making new products - now I have to order one for next season. Seriously, I suspect the skid will work just as all of the products I have from Evolution Powersports, looking forward to it.
Gene, if you read this, send me a PM when you have pricing on the skid.

Thanks, Karl

Not bashing or anything cuz I've really been lookin into a kmod or timbersled for my boosted PC 8. But I've got the OVS coupling adjuster on the stock skid an I can control the ski lift pretty damn good with it. What's the big difference the skids going to do compared to that?? Seems the suspension is similar in design as a stocker.

Its hard to put in it into words how much better it works, sometimes its one of those things you have to experience.
Some ppl have to ride it for a while to really figure out what it will do. Lucky for me I'm a bit crazy and will hit things most wont, and try lines that don't exist. Before the KMOD on my tm8 I was all over the place riding like that, always pushing it but more like a bloopers video that controlled riding. After I would hit anything and pull it off. The amount of control the skid gives you is unreal, even if I explained it perfectly and then you experienced it, you would look at me and say, Why didnt you tell me!!!!!
Even on the softest setting and the skis are up it still go's where you tell it to unlike a stock skid, just mind blowing.

Like I said even on a stocker its huge, I built my own coupler just to try it, it works better than without but the reality is no comparison in my mind and the stocker takes way more effort, and way more out of control. When I say that ppl don't think I'm out of control when riding, they shake there heads a lot but it looks impressive, but in my mind on the stock skid I am constantly finding myself think, oh chit, chit, chit,,,,, dam that was close, where as the kmod is sometime a oh .... never mind, I got this!

What shocks were on these setups?

I have the KMOD conversion, saving up for the Raptors.
 
Trying not to sound like an advertisement.....

I have had a few different skids over the years. Some had more performance improvements than others, all were in some degree better than stock. What was different this year on my Kmod was I never had to "improve" design for strength or modify for preference. I also have the Raptor upgrade all around. The adjustment for rider style, terrain, and snow conditions are endless. The differences are hard to describe but it's one of those mods that once you have it, and get used to that kind of performance, you will not want to live without it. It spoils you. Perfect example was on the weekend with the 2014 Cat demo ride. Had a steep face protected by that 15' knoll that alwalys kills your speed. I jumped that and landed in the transition. Usually that would mean wheelie city and no speed to carry. The Kmod just dug in, picked the skis up 12" and up I went. It was almost unexpected except that it's the norm on this skid. It does more for your riding confidence than a weekend with Tony Robbins.

As far as service, K-Mod is a service oriented company, which is an absolute pleasure to deal with. Kevin was out for a day ride with us in Alpine and spent a good part of his time learning guys on how to get the most out of his skid. True professional. I was already a K-Mod dealer so this Big Chute skid will just be another great addition to other Evo product.

Just want to say that I have seen the EXACT SAME THING on my Supercharged Nytro.

ABSOLUTELY LOVE THE KMOD SUSPENSION with the RAPTOR SHOCKS.

 
boost it- what # was your kmod set to when u did that climb

i have the Kmod conversion, on a Twisted 09 M8 SP 162" running 10psi on pure 100LLwiith a 3" when i set it at 4, fully coupled it still wheelie's quite a bit. when climbing the steep stuff, I've come over some steep ridges and the skis are 3 feet in the air as I come over the top.

How high are your handle bars
 
TO THE TOP

CAN'T HELP IT , that is the most comfortable for me, tried them all the way down , but felt unnatural

Understandable. But that will make the skis come up, when the bars are up and the sled is pointed up the bars force you farther back on the boards and puts your center of gravity so it pulls the skis up. But you also have a conversion so with both those in mind you have to deal with it. Although on mine which was the same as yours 100%, TM8. twisted, conversion except 3" but exact same everywhere else I ran on the lowest setting and even when the skis came up it still went where I wanted it to go unlike stock. But I rode with the bars all the way down too so it is what it is I guess
 
Agree with everything that's been said about the KMOD. I'm running a full Raptor setup on my SC300 1100T and a stock engine Pro. Av8er have you tried diff set ups on the skid? Call Kevin he will get your skis down. I would add 2 maybe 3 turns of more spring on your rear shock, 6 clicks more compression damping. On the front track shock I would take 2 turns out of the spring and go nearly full soft on the clicks. I would also take 2 turns out of the springs on the front. This is pretty extreme doing it all at once but it's easier to go past an adjustment and come back than just nibble away at it. You can also tighten up your limiter straps a bit but I would do the shock adj first. Take all the pressure off the springs and unlock the collars when doing the spring adjustment. Just grab the springs and twist.

Pretty sure he has and he has the conversion so there is no adjustment in the rear other than psi.
 
I do not have the Raptors- saving up for them tho

just Kmod conversion, with revalved floats, #3 revalving,
 
I am running pretty close to that pressure on a sled that weighs 100lbs less. Not sure what the diff in geometry is as that is super important. I would go up 20lbs and see what happens. Also, maybe spring for the EVOL chamber on just the rear shock and have them stiffen up the compression damping while they are at it. With the EVOL you can almost have a progressive bump stomp that should limit the travel in a nice progressive way. Don't give up, I've helped people to get Foxes set up where they really like them even after they have nearly given up. Tom's used to be a great resource but I haven't been able to get him on the phone or respond to emails at all this year. Must be busy....
