My girlfriend got a 2012 Yager 200i with a little less than 9,000 miles on it. I decided it was too slow, so I got a lot of Malossi parts from scooterpartsco.com. We installed a Malossi Variator, Malossi kevlar belt, 13.5 gr rollers, Malossi brake pads front and rear, and Malossi rear shocks. I also changed the oil and filter, and put on a new Heidenau tire. The difference in acceleration is the first thing I noticed. The bike gets up and scoots.
There was a bit of clutch judder when we bought it, and I've tried to get rid of it, but when I opened the case, the bell was tinted blue. So it's time to find a new one. I found a Polini one that is discontinued, and a Polini clutch as well, and the Dr. Pulley set of clutch and bell. I would prefer Polini, but haven't found anyone that has both pieces and a reasonable price. There's also some options on ebay out of Taiwan, but that's the next project. I wish she would let me put a pipe on it, but she likes the quiet sound of the stock exhaust. We've got a FACO windshield on order. Here's a photo of the Malossi shocks installed on the bike.
