We couldn't find a clutch that fit our needs anywhere on the market so we designed and built this one ourselves! We wanted better performance without having to break the bank.

Our Shorty Clutches are used by buggy and Scooter enthusiast all over the world because it was designed by people who ride (us), for the average joe that doesn't need a fancy name stamped on their parts, upping the price unreasonably! Our Exclusive Shorty Clutch kits produce a much quicker take off, better short hill climbing and less stress on your rear bearings and your wallet!!

Our KNM Exclusive, CN250 Shorty Clutch kit was not just designed for those of us on a budget but it adds a whole new dimention to take off speed too! Shaves 2 seconds off a 150' stock run! Smaller diameter clutch and bell reduces weight which is great for drag and Oval track racing or just getting that sluggish buggy or scooter off the line quicker! Creates more RPM's at take off so you can climb and get around corners and turns better! Comes with its own Chromed over Steel, Performance bell housing too! (Center Clutch "D" hole, flat side to flat side, measures (26mm)
*You may need to run a much heavier Variator weight and/or lighter main spring than you normally would. The Shorty Clutch spins fast enough that there's no need to lower your weights any more for that low end torque especially if you are running a taller sprocket or tire. It's best to install and "break in" your shorty first then tune your variator weights to your liking.

This Kit Fits most CN250 Buggies and Scooters such as the early model Hammerhead (pre2006), Freedom 250, Jet karts, BMS, ASW and most other 250cc vehicles with the CN250 engine! It will NOT fit the Carter Bros karts with the SYM engine.

COMPARE Top Clutch kits!....

Shorty Clutch Kit= Super simple to set up, super "torquey" and much less expensive than other top brands! Especially when you consider that it comes with a Chrome over Steel Performance bell housing too!

The DRPulley clutch has 6 sets of springs (3 arm and 3 pillow) to mess with. Great clutch but Good luck setting THAT up right for your needs! and it is very expensive ($250 to $300 then add a $60 bell housing, you'll be well over $300 smackeroos!!)

The Malossi is another great clutch that has these cool weights you screw into one of several positions into each arm as well as springs you need to adjust But, do you really want to spend weeks or more dialing THAT one in!! ($250 to $300 then add a $60 bell housing and you'll still be well over $300!)

Shorty Clutch Kit = 2LBS lighter than your stock clutch setup!!
Our KNM exclusive, innovative design will add to your low end torque and your friends envy! Spools up faster giving you a much better take off and hill climbing ability and will add about 2mph to your 0-25mph up hill speed to about any buggy or even more on an ATV or Scooter and get you there 2 seconds faster! AND, the Shorty with a performance bell housing is under $200!!! Not only do you get a much quicker clutch kit with the bell but you'll save well over $100 too!!

Plus, Check out our UNIQUE "Do it Yourself" WEBSITE LINK up top for more detailed info on this amazing Clutch Kit and we'll even show you how to install it! We don't know what more we can do to make this a better deal!

Due to the large amount of torque with our shorty Clutch, some heavier machines with a taller gear can "overtorque the Clutch (Such as the Roketa and SunL 250 Dune Buggies).
You'll already be near the top torque you can get out of your machine with some models. Our clutch is for "Stock" vehicles that have no torque to speak of to begin with such as the Pre "06"Hammerhead, Kinroad and some 250Joyners.

This is the Clutch Kit everyone is talking about because it works and doesn't cost an arm and a leg! It's simply the best economical Performance clutch on the market! Dramatic increases posted by members on Buggynews, MBRA, NEBA, Buggynuts and other top sites!

Here are some actual testing stats from one of our customers.
Although this was with our CF250 version, the stats remain the same on the CN...

KidNme,
The hardware I have installed for the test of the clutch:

Installed Shorty clutch kit in:

2007 Joyner Sand Viper
Stock exhaust pipe with gutted muffler
2 stage UNI air filter with K&N precharger on 2" elbow
High performance coil
Racing cdi with 12 deg of advance timing at 9000 rpm
iridium plug
AGM type battery
stock variator with 23 gram rollers
Stock spring behind clutch

Measurements were recorded at about 5 feet above sea level on flat dry asphalt at 75 degrees at 60% humidity.  I measured out 150ft.  I was timed with a stop watch and my max speeds were recorded with gps in the buggy.  I recorded 6 times with the stock clutch and 6 with the prototype.  3 times for each were in low gear and 3 in high gear.

Stock top speed in 150ft = 24.5 mph

Stock Run Low gear       Time
    1                                   6.40 sec
    2                                   6.44 sec
    3                                   6.42 sec
   
Stock Run High gear      Time
    1                                    7.2 sec  (bad start i think)
    2                                    6.2 sec
    3                                    6.3 sec

Now for the exciting part:

Prototype top speed in 150ft = 27.1 mph

Prototype Run Low gear       Time
    1                                           6.20 sec  (another bad start i think)
    2                                           5.11 sec
    3                                           5.80 sec
   
Prototype Run High gear      Time
    1                                            5.10  
    2                                            5.90
    3                                            5.12

So in conclusion we gained almost 3 mph in top speed in 150 ft and dropped 1.3 seconds of our fastest stock time!

I had no idea what to expect.  I was certainly surprised and impressed when I got these numbers.
It will be interested to see how the 17 gram rollers and new vented variator will affect everything. 

I hope you can use this info.  I certainly had fun testing it!
