I have no complaints, my grandpa is really jealous because he has been riding on elastomere since the eighties.

First off, WOW! Really nice full-susp.

A little on the heavy side. But that too me means a well built machine

Bottom line is, try hitting a fire road at 40+ mph with your buddy who is semi-pro hardtail rider and guess what happens to this "weekend warrior"; He takes a mean digger and broke his wrist and two ribs, ouch!! BUT for real it is a supurb climber and begginer/novice DH, AS well a it does pretty well on the pavement

First DH bike, and have owened now for 9+ years. Hard to part with it, and have thought about it many times!!

The suspension dampens even the most rough terrain, yet hinders the climbing effort very little. Very light bike. It is lighter than many of my friends' hardtails.

Wheels go out of true easily.

This bike kicks ass. I ride it almost every day on very technical terrain, and even small jumps. After a year of pounding, it is still going strong. I've only had to true the wheels and replace the brake pads -and routine maintenance. I ride sometimes with friends who have paid more for lesser bikes than this. The suspension system works awesome and makes off road riding feel like a ride on the road. I think you would have to pay over $2000 to find a bike that is noticeable better.

This is my first mtn. bike, I used to be a road rider.

Simple solid design.

The rims while lite, don't stand up to well.Bad seat.

Been riding this bike at least twice per week for a year and 1/2. I only ride off road and the average ride time is 2 hrs. I have only replaced the seat, filed down that stupid seat post stopper and shortened the seat post. (I can't stand doing downhills with the seat at the usual hieght.) This is an excellent bike. The smart shok is an added bonus. I feel that this and the 5000 reached their peak in 98. The 99s are a little step down. The bike is rough and ready and takes whatever I put it thru. It handles like a dream! And no pogo! I am impressed that little maintainence has been required. My only real complaint are the Sun Sub IV rims. I only weigh 150 and yet I still need to true the rear more often than I would like. I wonder if the squirrelly feel that some have attributed to the rear swing arm might just be the rim flexing? I will just replace these at some point. No big deal. A legend of a bike!!

Rode a Fisher Montare since 86.

great suspension set up- love the weight- superlite for full suspension-

tires gotta go- my front end slip all over on high speed singletrack- OH! and the seat kills!

Excellent XC bike- love the way it handles- very light , although I worry about the toughness of the carbon fiber swingarm.... anyway the suspension is tight- as long as you treat it right- and the components are decent. wanna good deal on one? www.bennetts.com- GET IT!!!

It definitely climbs much better than anything alse I've tried with a full suspension.
The wheelbase is long, hence the bike is a rail downhill. The fork is really stiff laterally, due to its homogeneous leg design, and is very accurate (point and shoot). The bike is fast downhill.
The intelligent fork is a real useful feature. I was afraid it is some sort of gadget, but thinking about it, it makes sense. What all the other front shocks suffer from is the difficulty to adjust them 'on the fly'. The headshock has this handy knob you can turn but it only acts on the precompression (so do most of the other forks top-knobs) and any motorcycle/car suspernsion specialist will tell you that dampening is what really matters. Wether you lean to the front of your bike or to the back, your weight distribution will change and you would need to adjust your shocks accordingly. The smart shock does it accordingly, regulating the oil flow hence the dampening.
It's an awesome idea, I'd even say the only way to go. Wait a few years and you'll see other bike/shock manufacturers will use a similar technology.
The XC ride of this bike on rough terrain is amazing. Even a bold rear tire does not lose traction on wet roots or rocks. It climbs anything, soaks up the bump and sticks to the ground. I am not sore after a ride as I used to be, and can resume normal butt activity.

I couldn't quite afford the K2-4000 this summer, so I settled for the K2-3000. I was certainly not disapointed. The bike handles extremely well, climbes like my HT (better actually, because the wheel stays glued to the ground rather than hopping over rocks like a HT does) and keeps me out on the trail like the Energizer Bunny (going and going and going).If I were to have any complaints about the bike, there would be none. But I might recommend improvements. First, I personally don't like V brakes (just my opinion) so I put a set of Maguras on the bike, and now confidence reigns supreme (check out the Magura comments, almost ALL five chilles). Second, when decending dirt roads with wash board the shocks are typically dampened for trail riding and the bike feels a bit stiff (not stiff like an HT). You could stop, loosen the dampening all the way and go, but I usually just go. Here is where I believe the Smart shock would be worth the money as found on the 4000. Not to worry though, next year K2 will be putting the smart shock on just about everything and the 3000, as it stands now, will be a memory.So, If you're in the market for a great bike and would like to take advantage of the end of season sales, this would be a terrific choice. I've seen this bike at local bike stores for under $1,000 this month. Simply put, that rocks!Enjoy!

Iam a previous 857 owner and loved it.It was an awsome climber for a F/S.and of course it decended as controlled and down right fun as only a well designed machine should......And then there was and is the K2 4000se.Two rides is all it took to convince me.To start with the press was right, the smartshock is a great advancment.It is without a doubt above all other shock's.It is easy to adjust and maintain .I resently upgraded the fork blades to the carbonfiber blades .It made the handling a little more predictable and it looks sexy .The rear shock with its full adjustabiility makes it a nobrainer to set it up just the way you like it.For riders 165-175 lbs. i recomend the most sensitive compression and four clicks from the most damping.After owning many f/s's . i can safely say Buy one and love life .

I rode this bike in Colorodo as a test. It rode great. I have no bad things to say about it and I am a hard tail hold out. I am so dissappointed with the reviews I just read about it. They are probably bull shit because they were all posted in a 5 minute span. Why idiots like to do this is beyond me.
This bike rocks for a FS bike. And if I were ever considering getting a FS it would be on the list. I think this page should be edited for the B.S posts and the posters should be ashamed of their selves for making the important information gathered here null and void.

I was a hardtail hold-out. It took this bike to convince me that full suspension is the only way to go. Not to mention the fact that I am now the ripe old age of 36, and these getting old bones took a beating on an aluminum hard tail. This bike is, how should I put this,"Awesome." That is the only way to describe it. This bike does everything better than my hardtail, including climbing. I didn't think it was possible. In fact, it climbs so much better, that after my initial ride I came home and measured the cranks to see if they were longer than my hardtail cranks. They weren't. After the easy climb, what comes next? That's right, the ride down. Most of the time it is possible just to stay seated and steer. This is impossible on a hardtail. Did I mention fire roads? No? Well, let me mention them now. The only thing I can say is that after a 1.5 to 2 hr. long ride I come home and I only feel 30 yrs. old. Oh, yea, did I mention that I LOVE MY BIKE......And because of the price...$710.00 dollars I have to give it 5 Flamin' Chilis across the board baby!!! So, if you are getting a little older, and coming home a little on the sore side after your rides, stop holding out and go full suspension.
