If you cannot do this then a rough rule of thumb is use an A size under 100 hours of engine run time and use a B size over 100 hours of engine run time. Its ALWAYS better to have a bit too much clearance than not enough, so if in doubt use an A size.","brand":"Rutherford Racing","offers":[{"title":"A","offer_id":42376960639051,"sku":"KTMGTBETERKTSPA-1","price":133.33,"currency_code":"GBP","in_stock":true},{"title":"B","offer_id":42376960671819,"sku":"C.PK.KT300.18on.TBI.B PC2668B-1","price":133.33,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/5171\/7707\/files\/store_carmera_2023414_15226_879_be21d0d6-4951-40a5-8580-9a8a18d61b85.jpg?v=1785509322","url":"https:\/\/rutherfordracing.co.uk\/products\/ktm-group-250-2023-on-tbi-top-end-rebuild-kit-tsp","provider":"Rutherford Racing","version":"1.0","type":"link"}
