The factory rollers weigh 14 grams and really limit the potential that's built into these motors. If you have the 2014 and older Leader 125-150cc leader motors with stock variator we recommend 10 gram weights. The stock weight from the factory is 10 grams. We recommend going for 9.5 gram set with a cylinder kit OR a pipe, and 9 grams with both a cylinder kit and a pipe.\u003c\/p\u003e","brand":"Scooterwest","offers":[{"title":"6.1g","offer_id":52435445186849,"sku":"M669456.B0","price":19.95,"currency_code":"USD","in_stock":true},{"title":"7.4g","offer_id":52435445219617,"sku":"M669456.D0","price":19.95,"currency_code":"USD","in_stock":true},{"title":"7.7g","offer_id":52435445252385,"sku":"M669456.E0","price":19.95,"currency_code":"USD","in_stock":false},{"title":"8.7g","offer_id":52435445285153,"sku":"M669456.F0","price":19.95,"currency_code":"USD","in_stock":true},{"title":"9.3g","offer_id":52435445317921,"sku":"M669456.G0","price":19.95,"currency_code":"USD","in_stock":false},{"title":"10g","offer_id":52435445350689,"sku":"M669456.H0","price":19.95,"currency_code":"USD","in_stock":true},{"title":"10.7g","offer_id":52435445383457,"sku":"M669456.I0","price":19.95,"currency_code":"USD","in_stock":true},{"title":"12g","offer_id":52435445416225,"sku":"M669456.L0","price":19.95,"currency_code":"USD","in_stock":true},{"title":"12.5g","offer_id":52435445448993,"sku":"M669456.M0","price":19.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0950\/4817\/1809\/files\/malossi-roller-weights_2_4.jpg?v=1781816972","url":"https:\/\/scooterwest.com\/products\/malossi-19-x-17-variator-weights-m669456","provider":"Scooterwest","version":"1.0","type":"link"}
