Machined from solid aluminium billet and built entirely in Italy, it delivers the kind of repeatable, micrometric adjustment that turns a fiddly workshop chore into a two-minute routine.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCNC-machined aluminium construction for exceptional rigidity and long-term durability under road and track stresses\u003c\/li\u003e\n\u003cli\u003eMicrometric adjustment positions let you set chain slack with pinpoint precision, protecting sprockets, chain and gearbox output shaft alike\u003c\/li\u003e\n\u003cli\u003eMounts directly into the swingarm with no modifications required — a straightforward swap that any rider can complete at home\u003c\/li\u003e\n\u003cli\u003eExact fitment engineered for the RN65 chassis, ensuring a secure, rattle-free installation every time\u003c\/li\u003e\n\u003cli\u003e100% Made in Italy — manufactured to the exacting tolerances Bonamici Racing is known for on race circuits worldwide\u003c\/li\u003e\n\u003cli\u003eAvailable in five anodised colours so the tensioner complements your bike's livery rather than hiding under it\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eEveryday Usability and Long-Term Value\u003c\/h2\u003e\u003cp\u003eA poorly adjusted chain is one of the leading causes of premature wear across the entire rear drivetrain. The CHAD11 takes that risk off the table. Because each adjustment position is micrometric, you get the same result every service interval — no guesswork, no drift between the left and right sides. That consistency pays dividends whether you are commuting daily, heading to a track day, or preparing the R1M for a weekend canyon run. The direct swingarm mounting means the tensioner works with the geometry Yamaha engineered into the RN65 frame rather than against it, so chain tension remains stable under hard acceleration and through suspension travel.\u003c\/p\u003e\u003ch2\u003eBuild Quality\u003c\/h2\u003e\u003cp\u003eBonamici Racing produces this chain tensioner entirely in Italy, using CNC milling to hold tolerances that cast or stamped alternatives cannot match. The aluminium is anodised to resist corrosion and abrasion, while the finished surface is available in red, blue, gold, black or silver to suit personal preference. The result is a component that looks purposeful on the bike and lasts as long as the machine it is fitted to.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe Bonamici Racing CHAD11 chain tensioner is designed exclusively for the following models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eYamaha YZF-R1 RN65 (2020-2026)\u003c\/li\u003e\n\u003cli\u003eYamaha YZF-R1M RN65 (2020-2026)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eBonamici Racing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePart Number\u003c\/th\u003e\n\u003ctd\u003eCHAD11\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProduct Type\u003c\/th\u003e\n\u003ctd\u003eChain tensioner\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eCNC-machined aluminium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFinish\u003c\/th\u003e\n\u003ctd\u003eAnodised (red, blue, gold, black, silver)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFitment\u003c\/th\u003e\n\u003ctd\u003eYamaha YZF-R1\/M RN65 (2020-2026)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMounting\u003c\/th\u003e\n\u003ctd\u003eDirect swingarm mount, no modifications required\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCountry of Manufacture\u003c\/th\u003e\n\u003ctd\u003eItaly\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Bonamici Racing","offers":[{"title":"Red","offer_id":53167200076042,"sku":"CHAD11-01","price":266.68,"currency_code":"EUR","in_stock":true},{"title":"Blue","offer_id":53167200108810,"sku":"CHAD11-02","price":266.68,"currency_code":"EUR","in_stock":true},{"title":"Gold","offer_id":53167200141578,"sku":"CHAD11-03","price":266.68,"currency_code":"EUR","in_stock":true},{"title":"Black","offer_id":53167200174346,"sku":"CHAD11-04","price":266.68,"currency_code":"EUR","in_stock":true},{"title":"Silver","offer_id":53167200207114,"sku":null,"price":266.68,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/CHAD11black.png?v=1780792667","url":"https:\/\/inter-pace.com\/products\/bonamici-racing-chain-tensioner-yamaha-yzf-r1-m-rn65-chad11","provider":"Inter-Pace","version":"1.0","type":"link"}
