{"product_id":"120cc-big-bore-kit-with-high-compression-piston","title":"120cc Big Bore Kit with High Compression Piston","description":"The TBParts 120cc Big Bore Kit offers a significant performance upgrade for Honda XR100 and CRF100 motorcycles. This kit is engineered to deliver more power by increasing displacement to 120cc with a 58mm bore.\n\nThe kit includes a high-compression 58mm piston, complete with rings, pin, and clips, matched with an aluminum cylinder that features a durable, cast-in steel sleeve for longevity. It also comes with a head gasket kit. This setup is designed to be safe for use with standard 91+ octane pump fuel.\n\nInstallation is straightforward, as the kit bolts on without requiring the engine case to be bored. TBParts notes that if you are capable of replacing a stock piston, you can install this kit. For those less experienced, they recommend consulting a repair manual like Clymer's, as the installation process mirrors that of OEM parts.\n\nThis big bore kit serves as an affordable alternative to a full OEM rebuild, providing a substantial increase in power and making the XR100 or CRF100 more enjoyable to ride.","brand":"TBParts","offers":[{"title":"Default Title","offer_id":52663946412344,"sku":"TBW9087","price":184.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687721960.jpg?v=1784331138","url":"https:\/\/store.motormia.co\/products\/120cc-big-bore-kit-with-high-compression-piston","provider":"MOTORMIA","version":"1.0","type":"link"}
