Variator DR3 Kit 150c Scooter

Regular price $149.95 Sale price $114.00

KNM, the original inventor of the "dual weight Variator" has improved our original DR2 Variator and now, 
we're making the DR3 right here in the USA!

If you liked our DR2, you're going to LOVE our DR3.
We designed the DR3 to ramp up your top speed on your scooter or ATV due to the lighter weight vehicle but also adds some low end kick to your Gokart.

Designed & Tested on TaoTao, Kinroad and UMspeed Scooters. This will work on almost every other GY6 150cc scooter.

No more trading your top end for low end torque like you do
in any other Variator. In fact, testing showed increases in top end speed too!!

Up to 8-10MPH or MORE on your TOP END over your stock 107mm! (& when using the heavier weights)
NO HYPE, NO FLUFF, No Bull, NO other Variator can touch our DR3 in your Scooter! 

With a Larger slide face and Slide ramps that are specifically designed to accentuate the travel of your Polygon weights, we have greatly improved take off and added top end! 
Our patented Deeper and steeper weight wells, add to your take off and smooth out the power band too.

It's the most tuneable and user friendly variator on the market AND Race tested, we knock the snot out of DRPulley variators, by quite a bit!

The DR3 kit comes with everything you need:

  • -115mm Fixed outer fan with 19 splines, 
  • -115mm KNM Performance modified variator, 
  • -Backing plate with durable nylon guides

    *New, customer requested-

Use one of the included 6 slider weight sets or
Mix & Match between 2 sets to tune your low end, change your shifting speed and your Top end! Our Race modified ramps are designed to get more out of your Polygon weights than any other variator. We accentuate the positive!

There's nothing else that even comes close to our DR3 and 
it just slides on and bolts right up in just a couple minutes! 
(1 fan nut, it's that easy!)
