KRX 1000 S2 Clutch Kit by Aftermarket Assassins
SKU: 102-1017
- Kit will work on any 2020-Up KRX 1000
- Our S2 KRX 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 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 55mph. 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.
- S2 kits include our AA Recoil magnetic adjustable clutch weights, our 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 84-100 grams, and up to 120 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
- You will need belt removal bolts (M10-1.25 x 50mm) which we have as an optional item

Will not be disappointed
Color: Black/Blue
Keeping in mind that I received this item yesterday (2/24/16), I absolutely love this watch. The reason I have so much confidence with this watch is because I've owned one other Timex similar to this one, and it served me extremely well and is still able to do so. First off, this watch is certainly aesthetically pleasing. The blue color around the face of the watch and outline in the band, goes really well with the black frame. It's just an overall nice looking watch. More importantly, the quality seems great. As I mentioned, I've owned a Timex expedition, which I've had for more than 2 years, and it's still working perfectly fine. The watch seems like it's put together very well and there's no loose or flimsy parts. One complaint that many people seem to have with Timex is the quality of their band. Unfortunately I'd have to agree, since the band on my other Timex that's still working like the first day I got it, cracked and broke and is only being held together by the nylon fabric on the other side of the band. You're not going to have that problem with this watch. It's a full nylon band with Velcro adjustment, for precise fitting. it feels extremely comfortable and you won't need to worry about the band cracking (although I'm sure there will be certain defects in a mass produced bunch). I will use this watch for work and running, and rarely plan on taking it off. Just to give you an idea, I also have a garmin gps watch that I love and obviously has more functions than this watch. However, the second I received this watch, I slapped it on and put my garmin to the side. This watch also looks amazing when you wear it. I'll update this feedback as needed, but I'm confident this watch will serve me for years to come, just as my other one has.

Greatest watch I've ever had, but changing batteries is near impossible
Color: Black/Blue
This is the 3rd time I've bought this watch. Same brand, same or very similar model. It has a chronometer, timer, alarm, and of course the clock. It has something I think is for "occasions" but I don't know what it does and don't really care about it. The watch is durable. It uses battery power efficiently. The indiglo is second to none. I just really really like this watch.
Having said all that, if you want to change the batteries, good luck, you'll need it. Once you manage to get the backing off of it and open it up (which is a little tricky in itself), it's like a comedy routine where you see some stooge open an electrical device and a buncha parts and springs go flying everywhere. And of course, they are so tiny, you'll never find them once they fly out. That was the exact scenario I found myself in the last time I tried to change the battery. It made me so mad I actually bought another brand of watch that I thoroughly researched. But that watch DIDN'T use battery power efficiently, and it had a host of other minor problems that added up to the conclusion that it was not nearly as great as this Timex. So, for the 3rd time, I found myself buying this Timex watch.
So it's a wonderful watch in every way except longevity because changing the batteries has historically been a nightmare for me.

A better Ironman design
Color: Black/Blue
I've been a fan of Timex watches for most of my life, paying about $30 for one in the 1960s, and that hasn't changed at all in 2010 because I'm still paying about $30 for my Timex watches. It is a rare case indeed when the quality of a product continually improves over several decades while the price remains the same. And as John Cameron Swayze would say in those live ads during the early years of TV, "Timex takes a lickin and keeps on tickin".
The MEGA deserves a good review after I have been using it for a while. You might also see it advertized as the "Oversize" because most distinctive about this design is its size, so tagging it with the name MEGA is entirely justified. It is massive in comparison to most of the other Ironman series of watches, and what seemed at first to be just another unnecessary Ironman 30 Lap design has turned out to be one of my favorites for all-around wearing. This new design keeps the clockworks of the standard size 30 Lap Ironman watches, it counts up and down, programs the same, has several alarms, and of course, it has the Indigo night light that works so well.
This is one of five different versions of the Mega available in the USA, and the only one with a Fastwrap Velcro wristband with blue striping and a matching blue bezel. Velcro wristbands are a favorite among many athletes and when it wears out, it can be replaced with either an identical factory band or one that is made of urethane rubber.
Overall, the Mega is a good choice for runners in need of a new 30 lap Ironman who can appreciate having a watch that is distinctively larger and what I would consider to be much better in appearances over the others of standard or mid size Ironman dimensions.
