We wanted better performance without breaking the bank so we designed a super quick clutch that's REBUILDABLE TOO and now you can have one!!

Our Shorty Clutches are used by Scooter and Go kart enthusiast all over the world because it works and just makes sense!

Much lighter (but stronger) than your stock clutch and bell, the Shorty, packs a punch but we won't classify it as a "Racing clutch" although many racers are using it as such. We simply consider it a better, quicker replacement clutch
that you won't ever have to buy again!

Our Exclusive Shorty Clutch kits provide a much quicker take off at a higher RPM for better short hill climbing and less stress on your brain and wallet!! A simple install that's one and done as we say!
Get the most out of your clutching AND when it finally comes time to replace it, you simply REBUILD IT, at a fraction the cost of buying a new clutch!

It is truly the "Working man's" Clutch with a touch of ingenuity thrown in! It's definately the last clutch you'll ever need!



This Kit Fits most CN250 Buggies and Scooters such as the early model Hammerhead (pre2006, with FNR), 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. Check the center hole dimentions before buying.
*Check the center holes on your stock bell housing and clutch for proper fit.
Our CN250 Shorty bell housing center hole has 19 splines and has a 14.7mm I.D

Our CN250 Shorty clutch center hole is 26mm, flat to flat.

Here are some actual stats from one of our customers who did some final "CF"250 Shorty product testing for us. Same clutch, different center hole.
We actually got slightly better numbers with our in house testing on a Hammerhead 250 but his aren't too shabby either for a very heavy Joyner 250 Go kart!


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


Installed Shorty clutch kit in:

2007 250cc 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!
