8 rollers = tons of options, run all 8 if your stock or dont know how to tune, run 4, run 2, etc. so many options. 8g weights come in it and using 4 of em put ya at 32g...very nice for kitted setups. ooo be a pro and drill out the weights for more variety!

just don't do it. especially with a kitted vespa. yuck. no weights except the ones from your stock variator and the set that it comes with will fit it.

i got this for my grande, and i can't help thinking there's a few things missing, it doesn't seem to be an exact bolt up replacement to the stock variator, but i'm not sure what kind of mods i have to make for it to fit properly because the instructions are in ITALIAN.

Here's the dish. The rollers weigh 8g each, so there's 64g of roller mass compared to the 40g mass of the stock 5-roller variator. Generally, heavier is not necessarily better, but it means you can run a stiffer contra spring and still pull the drive belt down.
The other big item is mass. The casing plus weights is 200g lighter than a stock assembly. That's less mass for the engine to spin up and it will help with acceleration.
sik as fuck
