Speedo puck most likely is toast. Inside there is a circular ring that engages with a notch on the front rim. Many times the notch wears out and it just spins. Next cause would be a loose cable, either on the puck end or the gauge end. If both ends of the cable are attached firmly then remove one end and see if it spins freely. Cables are known to snap internally fairly regularly.

Just to be clear...

We do not manufacture these. I came across them on the internet and thought they were funny so I bought a bunch. They are very popular. I apologize if anyone is offended as that is not the intent. Have a great day!

Hoca is a completely different ballpark from Koso, hence the huge price difference. We have never had any issues with Hoca products, except in cases where they are TOO powerful and end up loosening head studs even with loc-tite.

We have sold Koso for 2 years with mostly no issue, it's just been since June or so. You get what you pay for. If I get around to it I'll post a comparison of Dr. Pulley, Koso, and Hoca variators. You can definitely SEE the quality difference. You can also FEEL the difference in balance and weighting of the products.

To those of you that have Koso now, I certainly hope you never have any issue with them. Happy Scooting!

Not available anymore.

As I said they are hit or miss. Quality was fine at the beginning of the summer. You are absolutely right about dealing with warehouses and manufacturers, especially ones from overseas. They sell the top quality to their big distributors and sell the "rejects" for cheap to lower volume buyers.

I know tvnacman sells only products he personally tests. That is why you got a quality one from him. I opened the shipment from Koso and was sorely disappointed. This last batch I will absolutely not sell to anyone unless I want unhappy customers (or former customer). I'm not going to ship them back as it would cost more than they are worth. I will sand and polish these and use them in my rental scooters.

>> wow greg that's a cheap price that $18 is that with rollers if so what weight 50cc or 150cc ? and how much to ship ?

Both at the same price. We are out of the good 150s, have one 50 left. I'm not going to buy Koso variators anymore. I have not had any issues with the rollers or any other parts.

Your experience may be different. Obviously if Koso ONLY sold crap they would be around anymore (at least under that name). However you won't get Koso Variators from me.

Another member mentioned that Koso Variators were a good deal, cheap for the price.



We stopped selling Koso Variators at our shop. Here's why.

They are cheap and cheaply made.



Our latest shipment of variators direct from Koso, every single one of them had manufacturing defects. The face was not smooth, it was ridged so much it made a nice noise when you ran your fingernail across it. Until they are worn down they will shred your belt. I've seen it happen within 50 miles. Quality variators are polished smooth so there is no extra wear on the belts and there is a good surface to grab.



The cut edges on the back are razor sharp. Why does this matter? The variator guides (which are plastic) slide up against the sharp edges (which are cut aluminum). The guides won't last very long. The plastic guides themselves are made from a lightweight plastic that will not last as long as Dr. Pulley ones. The ramps are coated with a teflon-like substance. It scratches off pretty easily leading me to believe it is not teflon or it was not applied properly.



The ramp angles themselves are pretty good and it does perform well. Until it shreds your belt or wears through the guides and locks up.

We sell Dr. Pulley, Koso, Hoca, Malossi, and a few other brands. The only brand I won't sell anymore unless asked is Koso. Even then I will not offer my generous warranty on it.

Take this as you will. Its not a dump on Koso. They are extremely cheap and we sell them (in store) for $18. We sell the Dr. Pulley for $129 installed and Malossi for up to $250. You get what you pay for.

Have you upgraded the crank or bearings? Bearings will not last that long with the extra torque and RPMs.
