Fits all 2024 - 2026 Kawasaki Ridge 1000 models (92HP & 116HP) including Crew models
**CHECK OUT OUR 7 VIDEOS ON THE EXTENDED INFORMATION PAGE***
Options offered are 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 kick 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. Add our AA Ridge slip-on exhaust w/spark arrestor which is just what your machine needs! We set out to produce an exhaust that looks great, sounds great(without being overly loud) and most important of all - performs great! For more information on the exhaust features please follow the link below. Kit Options: Big horsepower gains for standard 92HP models and 116HP XR models! This kit takes both HP levels up to to 145 estimated crank HP. 92HP Models: 116HP XR Models: **New feature unlocked as of March 2026: We now have the ability to desensitize the belt slip detection system, which is extremely sensitive. The factory setting immediately puts the machine into limp mode when any amount of belt slip is detected. This is especially annoying for those with the heavier Crew models or those running larger size tires. We turn down the sensitivity enough to be able to get up those slight inclines but still maintain the safety feature so if an abnormal amount of belt slip is detected it will still limit throttle to protect against excessive wear.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 and towing Smoother throttle mapping down low as OEM seemed to be jerky in all modes Slightly increased idle speed to smooth engagement and keep the CVT engaged for more predictable engine braking. We found models with AC and AC turned on constantly kicked the CVT system in/out of freewheel making it hard to control. We tested some different clutching and found it could also be controlled this way, but it was much better to control this via the engine idle calibration. Full throttle/power in reverse (factory limits reverse throttle) AA's wicked timing curve - Switch fuel modes without having to re-flash (via throttle mode switch):Sport and Normal throttle mode: Work throttle mode: A great fuel curve that gives much better low end and all around more 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! Optional seatbelt limiter disabled Speed limiter removed Rev limit at a safe 9800 RPM (Stock is 9500 RPM) Best peak power when tuned is 7600-8000 RPM at wide open throttle in the 30-50 MPH range Very easy to use tuner that can also check and erase most trouble codes Easily data log 29 parameters with 1 push of a button and review on your Windows PC/laptop 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 VelcroIncludes Level 2 Tune: If you have any specific tuning 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 S1 Ridge clutch kit packs a huge punch! No matter the terrain, they hit hard and just keep pulling for days. On the farm, 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 original Ridge clutch kit! When Kawi first released the Ridge, we had one on order so we could quickly get to work. After hundreds of different tests with weight profiles, clutch setups, and spring changes we found the best combination possible. Overdrive Option: These clutches do not shift fully and therefor your RPM runs high quickly at higher speeds. Shifting further into overdrive helps give you more top speed, and higher speeds without so much RPM. To do this, we had to design a custom weight profile with slightly added length. We have two methods for this. The best option is our billet overdrive Revolver cover which allows the clutch to shift further and properly limit and this is much stronger than the cast OEM plate. The second method is to use our overdrive washers to space your OEM cover out which works, but is a little more hassle to install and more parts to worry about... plus, the OEM cover is weak, so it's best to replace it if you can. Note: The Revolver Overdrive cover should not be installed with our Overdrive Washers. Running the Revolver Overdrive cover with our Overdrive Washers could cause the primary clutch to overshift and potentially damage the belt/clutches.With the overdrive option we see around 76-79 MPH with our cruiser setup, and you can see 80-85 MPH with our standard or performance clutch weight setups The Ridge has some clutching issues right out of the box because the OEM weighs are soft, just like the KRX models. Being these vehicles are geared so low, the clutch constantly runs at full shift over 50 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. 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. AA Ridge weights now come with a bushing design for an even smoother engagement over stock. We have 3 different clutch weight configurations for your riding type, and they can be switched out when/if needed:For reference, stock cruising RPM @ 50mph is normally 7700-8000 RPM Standard clutch setup: Our main clutch weight setup guide. This is the best middle ground for belt grip, performance, and drivability. Cruising RPM @ 50 MPH is typically 6200-6500. Peak RPM at wide open should be 7600-7800.Cruiser clutch weight setup: On our clutch weight setup guide, it will list a cruiser option for those wanting to lower overall RPM to make the vehicle quieter. This is aimed at those that don't need every horsepower, but want a smoother/quieter ride. Cruising RPM @ 50 MPH is typically 5500-5800. Peak RPM at wide open should be 6300-6700.All our performance setup: Our clutch weight setup guide, it will list the all out performance setup which has you run the weight arms with no magnets. This will give you maximum RPM/Performance from your ridge. This will engage a little higher than the other setups and will run higher RPM all around, but will absolutely rip if that's what you are looking for. Cruising RPM @ 50 MPH is typically 6500-7000. Peak RPM at wide open should be 7800-8100. Stage 1 clutch kit includes our AA Recoil magnetic adjustable bushing style clutch weights, AA primary spring & setup guideline. Our setup guideline will let you know how to set your weights for stock horsepower, tuned horsepower, 27-35" Tires, paddles & more. Fully adjustable magnetic weights are easy to use and adjust Adjustable from 85-109 grams By design, our clutch weights have more tip weight mass with a more aggressive profile, 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 and better power transfer to the rear wheels. Close to stock engagement which is very smooth 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, the S1 kit is just for the primary clutch. Make sure you check peak RPM @ 30-50 MPH, it should be 7600-8000 RPM for peak performance.

You will need belt removal bolts (M10-1.25 x 50mm) Highly recommend upgrading to the billet overdrive Revolver Clutch Cover with Tower Lock for increased strength an further clutch shift out
