I've never heard of a. Dr pulley variator completely destroying its own sliders . you may have been the lucky one to receive a defective variator . I think alley mentioned they where not good for top end " due to the belt not climbing as high ", other then that from what I've heard they are suppose to be higher quality. I've always used koso variators ,even though the last two I bought where a different casting and the back plate was also different . this kept the belt from dropping all the way in the variator. That's why I'll no longer buy a koso from someone I've never heard of.

Yeah, maybe. The heavy wear on the ridge at the base of the fingers made me think that might be what trashed the sliders. Threw the boogered up sliders in the trash last weekend, and now regretting that. They would have been a cool mantle piece! Anyway - have you heard of this Motorio variator? For some reason I have the notion "Motorio" is high quality stuff, but maybe that's my imagination speaking. This product caught my eye because it (supposedly) has an interesting quirk: 3 of the ramps are cut for high end (and use heavier weights), and the other three ramps are cut for low end (and use lighter weights). Kind of an interesting concept ... www.ebay.com/itm/SCOOTER-150CC-GY6-HIGH-PERFORMANCE-RACING-MOTORIO-VARIATOR-SET-NEW-GENERATION-/191446787656

I have read a few threads about them before and then if I'm not mistaken the results weren't that great , but most I've read where mainly asking for info on the dual ramp variator. I wouldn't mind trying one however I wouldn't buy one unless I had an extra 80 bucks with nothing better to spend it on. If I had a busted variator and really needed a new one I would buy a koso .

Add all the rollers up, do the math and the equally divided roller weight = 10.66 grams.
Also roller versus slider. Betting I can take a standard variator and put 11g sliders in and you wouldn't know the difference or see it on a RPM reading either.

I agree , the only difference I noticed with sliders vs rollers was the sliders seemed to rise the rpms a little higher on takeoff but they ended up having the same top end achievement " that is in rpms and mph . I based this on having tuned my scoot to reach a top rpm around 7500 on a straight run.

I think one set of ramps is steeper than the other set, meaning the steeper set would need more force to make the rollers go up them. That might make the bike accelerate quickly, by keeping the steeper ramp rollers closer to the center, and then when the other set of rollers makes it up the steeper ramps, it would push the variator closed more. It might effectively give you "lighter" weight until enough rpms were reached to "trip" the steeper ramp setup. I am sure you could figure it out with some math using the angles of the ramps at any given location, and their distance from the center, the rpms, and the opposing spring pressure, and the angle of the pulleys, but algebra and calculus are not my strong suits. If someone can tell me how to calculate it, I'll put it on a spreadsheet so anyone can use it.

Bottom line you need a given amount of force to overcome the contra spring , It looks like a great idea , but you still need the correct amount of force to push the clutch opened and the variator closed .
