SKU: 113-1016-1-C
Fits all 2025 KRX 1000 models
- **2020-24 models us a 4 arm clutch instead of 3 arm, for 2020-24 models, see that specific listing***
- Lock and load your Kawasaki KRX 1000 and get ready for some serious kick! The KRX 1000 is a great machine, but Kawasaki left a ton of room for improvement on the table. This simple kit is the best way to wake up your KRX 1000 as it comes with our proven ECU tunes which are loaded via the DynoJet Power Vision 3 ECU tuner. The tunes add some amazing horsepower from low end to high end RPM and really give your machine that "snap" you're looking for. Our AA Stage 1 clutch kit compliments the tuning perfectly by more efficiently transferring power to the wheels and ridding yourself of the very lazy factory clutching setup.
- Kit includes: AA custom tuned PV3 tuner and Stage 1 Clutch Kit.
- Big horsepower gains! The KRX factory timing map is very de-tuned which allows us to easily wake things up
- Quicker throttle response and power delivery
- Throttle by wire tables are modified for better response, especially in high range. Low range throttle mapping is a little better, but still left mild for good crawling.
- Full throttle/power in reverse (factory limits reverse throttle)
- AA's wicked timing curve built for 91-93 octane fuel
- A great fuel curve that gives much better low end (as well as all around) power as the factory map is very lean in key areas.
- Accelerator enrichment is optimized for better fueling and vehicle response when stabbing the throttle
- Fan on/off temp lowered to 185/180 degrees Fahrenheit (Stock is 189/183)
- Winter tunes (runs hotter but safe coolant temps) available for those with cabs/heaters in cold climates. Easy to switch when seasons change!
- Seatbelt limiter disabled
- Speed limiter removed in low and high gears
- Rev limit at a safe 9800 RPM (Stock is 9500 RPM)
- Best peak power when tuned is 7000-7300 RPM at wide open throttle around 50 MPH in a full power run
- Very easy to use tuner that can also check and erase most trouble codes
- Easily data log 25 parameters with 1 push of a button and review on your windows computer later
- No mess of having to send in your ECU, and a safer way of programming your ECU (easily go back to stock tune)
- Mount using the supplied dual lock Velcro
- Level 1 Tune: Built for the OEM exhaust (cat removed is okay) and 91-93 octane. Gains 10 RWHP in some areas, and on average 7-8 RWHP when combined with our clutching. This takes your KRX from roughly 112 factory rated crank HP to 125 HP.
- Level 2 Tune: Built for an aftermarket exhaust (slip-on or full system) and 91-93 octane. Gains 16-17 RWHP in some areas, and on average 14-15 RWHP when combined with our clutching and exhaust. This takes your KRX from roughly 112 factory rated crank HP to 135 HP.
- Race fuel tune 95-100 octane maxes out our timing curve to where we see peak power. This gives you another 3-4 RWHP on average over the pump gas tunes.
- More tunes are coming, if you have any specific needs please let us know!
- Why AA tunes over others? We have been tuning UTV's with CVT clutches for a long time, longer than almost anyone in our field going back to the 800 RZR. Tuning a CVT vehicle properly is not an easy task as you have so many variables at one time. We spend the time to wheel dyno (with actual UTV tires) correctly per modification, and have advanced ECU calibration and clutching knowledge to do so. Every change in horsepower can result in us changing clutching several times. We also develop most of our supporting mods so we know everything works correctly, and build parts to fit the vehicles needs. Lastly and honestly the most important; we then back up our results with real world data logging on local trails and our facility on 110 acres. It's this combination that truly makes the difference and why AA normally has a faster vehicle with the same or less rated tune horsepower.
- Our Stage 1 KRX 1000 clutch kits pack a huge punch! No matter the terrain, they hit hard and just keep pulling for days. On the trail or at the race you'll notice wicked acceleration and instant clutch response when getting back into the throttle after hammering that corner. In the dunes you'll see the same benefits, but also have much less bogging when climbing that big dune. The machine will hold RPM so you can get where you need to go, and get there faster! Going mudding? Our mud setup will help turn those tires through the thick and deep with much better RPM and wheel speed that's key to climbing out of that hole. Are you a rock crawler? Our smooth engagement and precise feel down low will give you the confidence to tackle any obstacle. We have a huge amount of CVT knowledge, a great passion for the sport, and spent many hours testing different setups in the real world. We know you'll be extremely pleased with the performance gain from our clutch kits!
- The KRX 1000 has some clutching issues right out of the box because the OEM weighs are soft. Being these vehicles are geared so low, the clutch constantly runs at full shift over 55 MPH. Being at full shift for so long wears the weights away at the tip, and will groove them. This makes the vehicle want to sit at full shift, and shift inconsistently. Our weights go through two hardening processes and are through hardened for the most longevity possible. They have no bushing as it's not needed with the hardened weight, which also makes them last longer. Not only that but they are fully adjustable for different tires/modifications and perform better because of how the mass is placed on the arm.
- Stage 1 kits include our AA Recoil magnetic adjustable clutch weights, AA dark green primary spring & setup guideline.
- Our setup guideline will let you know how to set your weights for stock horsepower, tuned horsepower, 30-35" Tires, paddles & more.
- Fully adjustable magnetic weights are easy to use and adjust
- Adjustable from x-x grams, and up to x grams for turbo applications if you purchase our optional Slug Magnets
- By design, our clutch weights have more tip weight mass, so they grip the belt harder and accelerate faster... yet still crawl even better than OEM.
- A must-have when changing tires, tuning your machine, or running paddles
- Cooler running belt temps from a more efficient power transfer which results in longer belt and clutch life
- Big acceleration gains an better power transfer to the rear wheels.
- Close to stock engagement which is very smooth (Higher engagement springs available if needed for racing)
- Our Recoil clutch weights are easily adjustable with simple magnets. They have a custom AA profile, the BEST coating on the market (nitrocarburizing) which has increased wear resistance, improved fatigue strength, and added surface lubricity. These clutch weights also offer great performance, and the ability to tune for many different applications or modification in the future, without the need to buy extra parts. The magnetic weights are the best option to properly place the mass where we need it on the weight for best performance for your application.
- We found the stock secondary clutch to work very well, this kit is just for the primary clutch.
- Make sure you check peak RPM @ 50 MPH, it should be 7000-7200 RPM for peak performance. See here on how to test: https://aftermarketassassins.com/tech-blog/f/clutch-testingverification#
- See installation video here: https://www.youtube.com/watch?v=Vop-L1y0IK4 (Video shows 4 arm clutch, installation is similar)
- You will need belt removal bolts (M10-1.25 x 50mm) which we have as an optional add-on item
- Highly recommend replacing your factory belt with our AA Stryker Belt for longer belt life and consistent performance.

Does the job, but assembling by yourself is a nightmare
Size: 4 Panel-88'', Color: Black
Does it do the job? Yes, although as others said there are small gaps but it's not a huge deal. The price is also good. But the reason I'm giving it a 3/5 is simply because the assembly for this was a complete nightmare. I honestly don't think I would recommend this to anyone unless they have another person to help them assemble it, because doing it by myself was terrible. I don't think I'd buy this again, I think I'd opt to just spend a bit more money and save myself the trouble personally.

Reasonably adequate room divider
Size: 4 Panel-88'', Color: Beige
I'm reviewing this as I assemble it.
Couple things:
1. I didn't expect as much assembly. I've ordered dividers before and they more-or-less came as one unit. Sometimes the panels needed screwing together. These require complete assembly and come largely as three rods: two make up vertical columns and snap together. Another one (called part "C") makes the horizontal columns and you have two of these per panel (one attaches to part "A" and the other part "B"). These parts are metal with a plastic shim. Using the wood screws to attach to part "C" is a real pain in the neck. There's not much holding the panel in place so it's a little tricky.
One tactic I've found while I'm assembling that works for the initial connections from parts A and B to their respective "C" rods is to hold the screw in place with a screw driver and then rotating the rod around the screw. This will do a number on your hands if you aren't wearing gloves. This obviously doesn't work when completing the connection.
Using a driller driver on this is really near impossible because there isn't anything you can use to secure it in place. You can use it on the first panel, but as it gets longer, it becomes increasingly difficult and because it isn't wood, it's really tight. I considered drilling larger pilot holes but since there are only 4x4=16 screws I need to screw in, I just decided to use my screw driver to complete it.
2. Also related to assembly. When completing the panels (attaching parts "A" and "B" to parts "C" that have the cloth cover on it), you have to be careful that when you tighten that side that it isn't loosening the other side. Because the pilot holes are so tight, you can end up rotating the rod, which rotates it in the same direction as looser on the original side. Having someone hold the "C" rod in place while you screw it in is probably the easiest approach. I didn't have a 2nd person, so I just had to keep flipping back and forth and tightening both sides as I screwed it in. Not the worlds biggest deal, but annoying nonetheless.
3. The way the instructions are written, they seem to suggest building this thing progressively; that is, you do panel 1, then 2, connect them together, then do 3 and connect it, etc. I took a different route that I suspect saved me quite a bit of trouble, and I assembled all four panels first and THEN connected everything together.
4. For the love of God make sure you check that the plastic tip is on the same side for every panel. Otherwise, you have to take one side apart again and reverse it. On the bright side, if this happens, you've essentially bored out the pilot holes to be the correct size... which is having me question if I shouldn't have just bored them out to the appropriate width in the first place.
5. Attaching all of the panels together is also an enormous pain in the ass unless you happen to have an 88" long elevated surface. Attaching the legs either requires you to elevate one side, which will invariably twist the inexplicably cheap material in the bottom connectors... or you can attach them sideways... or you can put this thing upright, having two people hold the panels in place while you use the allen wrench to tighten the bolts on the underside. None of those are particularly great options.
NOW on to the utility itself.
1. The panels do let some light through (I didn't believe their advertising, and that was one of the reasons that I bought beige, is that I wanted it to not be too dark). They aren't transparent though, so it isn't that far off from their description. They functionally work great, and keep the mess of wires hidden and when I'm sitting at my desk, actually reflect quite a bit of light into my office. Great!
2. My wife has described these as "the most hideous piece of furniture ever conceived of by man." So it does not have spouse approval factor. Granted, she will seldom be in my office area, so that isn't the end of the world.
3. These are really hard to align in a way that doesn't look a little tacky. There are some plastic connectors but they don't do a bang up job of keeping these in place. Each panel is slightly tilted and it's... quite obvious. I may at some point make my own improvements to these to help make them more level. It's not a particularly expensive product so I wasn't expecting much so it's fine and I'm not going to ding them on the rating because of it.
All said, would I buy this product again? Probably not. It's assembly was ~90 minutes which is about 75 minutes longer than I was anticipating spending on this (not including the 5 minute writeup that I'm doing here). But am I going to return it? Also no, if for no other reason I'd be just as annoyed taking it apart and putting it in the original box to return it.
