Set of 6. SKU: 1200-1113. Key Features Patented non-round geometry — eliminates flat spots and uneven wear common with circular weights Broader gear ratio — variator retracts and extends further than OEM, improving both takeoff and cruising Self-lubricating SL9 nylon composite — resists heat buildup and reduces internal variator wear Available in 9g to 13g to match your riding style and modifications ISO 9001 certified | Made in Taiwan Specifications Dimensions: 21mm diameter x 17mm width Quantity: set of 6 Available weights: 9g, 9.5g, 10g, 10.5g, 11g, 11.5g, 12g, 12.5g, 13g Compatibility Vespa GTS 250 \/ 300 (Quasar, HPE, Super Sport) Vespa GTV 250 \/ 300 (Sei Giorni \u0026amp; Heritage models) Piaggio BV 250 \/ 300 \/ 350 \u0026amp; MP3 250 \/ 300 (Beverly) Aprilia Scarabeo \/ Atlantic 200, 250, \u0026amp; 300cc Royal Alloy GP300S Piaggio Leader 200cc engines (Vespa GT 200, Piaggio BV 200) California Prop 65 Warning: www.p65warnings.ca.gov","brand":"dr. pulley","offers":[{"title":"Default Title","offer_id":48045311328443,"sku":"1200-1113 10 G","price":40.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/thriftyscooters.com\/products\/dr-pulley-21x17-sliding-roller-weights-vespa-piaggio","provider":"Thrifty Scooters","version":"1.0","type":"link"}
