The only differences are:\u003cbr\u003eThe Beta piston is 0.01mm bigger in diameter i.e. a size B Beta piston is the same as a size C S3 piston (78.97mm).\u003cbr\u003eThe Beta piston has a chamfer on all 4 corners of the bottom edge of the skirt.\u003cbr\u003eThe Beta piston has a small machined groove to help fit and remove the c-clips.\u003cbr\u003eThe anti friction coating has radius corners on the Beta, rather than square.\u003cbr\u003eThe skirt support lugs are little bit bigger on the Beta, so it's about 8 grams heavier then the S3 version.\u003c\/p\u003e\n\u003cp\u003eNone of the above will affect the way the bike runs so I'm more than happy to recommend this S3 piston for use in the Beta Evo 300.\u003c\/p\u003e","brand":"S3","offers":[{"title":"A","offer_id":44160082477236,"sku":null,"price":172.35,"currency_code":"GBP","in_stock":true},{"title":"B","offer_id":44160082510004,"sku":null,"price":172.35,"currency_code":"GBP","in_stock":true},{"title":"C","offer_id":44160082542772,"sku":null,"price":172.35,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0631\/9934\/6868\/files\/piston-s3-racing-for-beta.avif?v=1773404688","url":"https:\/\/camiomoto.co.uk\/products\/s3-300-piston-kit-gasgas-pro-sherco-trs-beta-scorpa-vertigo","provider":"Camio Moto","version":"1.0","type":"link"}
