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. Designed & Tested on TaoTao, Kinroad, UMspeed Scooters and will work on almost every other 150cc scooter with the GY6 150 motor!
No more trading your top end for low end torque like you do in any other Variator, in fact testing showed some increase in top end speed too!! Up to 10-15MPH or MORE on your TOP END over your stock 107mm! (& when using the heavier weights) NO HYPE, NO FLUFF, 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 tunable 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,
-KNM Race modified variator,
-Backing plate with durable nylon guides
-Industry leading "Oil infused" Center Boss pin and
-NEW- $90 Free Sliders!) 3 sets of quality SLIDER weights, instead of Rollers
-10 gram sliders,
-12 gram sliders
-15 gram sliders* *New, customer requested- Includes heavier 15g weights (Instead of 14's) for even more top speed in your scooter!
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!)
This kit fits TaoTao GY6 150cc Scooters as well as MOST other GY6 125/150cc Scooters from China.
