Pretty close in price. A little cheaper than what I usually see for the real Drs since shipping is free. Another good thing is that scrappydog usually gets stuff to you in just 2-3 days.

Worth a try for sure

Just found this posted at scoooterinvasion. Josh over there dug this up and i found it to be pretty interesting. Dr.Pulley is pissed about their sliding weight being cloned. A post by Josh, or Areomyst Snipped this from silverwing600.forumotion.com/ Watch the videos, they're somewhat interesting... at least, to a geek like me they are.

Happy to have been informed of this problem by a respected scooter after-market parts supplier. Hi, The tribological properties (low friction coefficient, high wear-resistant & Aluminum-compatible etc ) is very important. We do want to protect our intelligent property but we’re more concerned about all users’s right to choose the genuine parts to avoid any harm from FAKE sliders’s poor quality. See explanations below and the video series of Heat buildup 1, Dr.Pulley SR1814,temp. rising to 40℃ ... in www.youtube.com/watch?v=PSGHZ9u3F_cThe material used for Dr.Pulley’s slider SR1814 is a proprietary self-lubricated composites ( SL-9T series ), it’s Aluminum compatible so the Aluminum-made variator will almost not be worn by Dr.Pulley’s SR. Moreover the friction coefficient of SL-9T series is extremely low so the friction heat buildup is very low. (Dr.Pulley SR’s friction heat buildup will be only 38℃ after 128,000 cycles of reciprocation test ) But the material used in FAKE slider is very abrasive that means the Aluminum-made variator will be worn very seriously by the fake slider and the friction coefficient of FAKE slider’s material is extremely high so the friction heat buildup is very quick and high.( Fake slider’s friction heat buildup will be quick and high such as 53℃ after 43,000 cycles of reciprocation test for RPM’s fake slider or 53℃ already after 11,000 cycles of reciprocation test for KOSO’s fake slider ) www.youtube.com/watch?v=Mwmkw9E8-kc&feature=channelwww.youtube.com/watch?v=QGgYJ6TcTXI&feature=channelwww.youtube.co/watch?v=7ZeLF9SUkx8www.miniatvtech.net/index.php?showtopic=500 |

The Dr. Pulley people shouldn't worry about it. If the "fake" ones are so bad then the word will get around quick and nobody will buy them. I almost did buy some and then decided not to out of a gut instinct.

I bought a set of the orange sliders from Scrappy and so far I like the performance. I'll give it a few hundred miles and see if the variator looks worn. I've got a spare stock variator with only a few hundred miles on it (with rollers) to compare it to. Unfortunately it's snowing today so it may be awhile before I can ride a few hundred miles  Jim |

Kinda cool that they don't just tell you they are superior, they do the tests and prove it for you.

Let us know how that set goes for you Jim, thanks! Fox, i almost got some too but bailed on the idea for the same reason. They just arent that much cheaper than what i know works good |

Yeah so far I'm happy with the Scooter Ninja ones MRP is selling. They were only like $19.98 I think and seem to be working fine. I'm betting Dr Pulleys patent has expired and other people can make them now. That will drive the prices down across the board. They didn't look cheap or cheesy, they looked good! I'll pull it apart and check the wear after a 1000 miles or so. |

I havent bought from them but im sure they are real. Anything with the Dr.Pulley name and logo should be safe.
Im not saying the others arent "safe", time will tell if they are as good or close....

Ok, here's the short term results... Totally unscientific but since I don't have a complete laboratory, it's all you get :2cents: I compared a variator used with rollers for a couple hunderd miles to one that had a couple hundred more miles on it with rollers and then 115 miles with the Scrappydog orange sliders. The wear patterns were a bit different but I figure that's to be expected. There didn't seem to be an appreciable difference in the amount of wear although in one or two of the ramps had what looked like deeper scratches. I'm thinking that may have been caused by some debris as it was only a bit in one and a bit less in another. I just transferred the sliders to a new NCY variator, I'll pull that apart after awhile and see what the wear looks like there. BTW, I really like the ramp design on the NCY, seems to give better takeoff and top end than stock.  Left is the stock with 200 miles on rollers, right is 400 with rollers and 115 on sliders. Jim |

Very interesting, looks like no abnormal wear too me. I'm gonna wait and check mine in a couple more weeks. By then it will have been about a month with the new sliders and around 400-500 miles. We'll see if I get any abnormal wear in my NCY variator.
