OZ's forging process aligns the grain structure of the metal for maximum fatigue resistance — a process refined over decades of World Superbike and MotoGP campaigns. The result is a wheel that holds its geometry lap after lap under the sustained lateral and braking forces generated by the M1000RR's 212 hp inline-four.\u003c\/p\u003e\u003cp\u003eThe Cattiva six-spoke layout distributes load symmetrically around the hub while keeping material only where finite-element analysis confirms it is structurally necessary. Every gramme removed from a rotating component has a disproportionate effect on performance compared with static mass reduction, which is why teams in the Superbike World Championship continue to choose forged magnesium over all alternatives.\u003c\/p\u003e\u003ch2\u003eTrack Use and Intended Application\u003c\/h2\u003e\u003cp\u003eThis wheel is designed exclusively for closed-circuit competition use. It is not intended for road registration or public road riding. Riders campaigning the BMW M1000RR K66 at circuit level will find the Cattiva rear wheel reduces lap times through improved corner entry stability, faster direction changes and crisper drive out of slow corners. Part number C6271BM60X.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis wheel is a precise fitment for the BMW M1000RR K66, model years 2021 through 2026 only. It is not compatible with other BMW models or year ranges. Fitment requires an aftermarket rear sprocket carrier — the original BMW sprocket carrier does not fit. Installation of suitable quality bearings (supplied) and, where applicable, the included spacers is required before fitting.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrand: OZ\u003c\/li\u003e\n\u003cli\u003ePart number: C6271BM60X\u003c\/li\u003e\n\u003cli\u003eModel: Cattiva\u003c\/li\u003e\n\u003cli\u003eType: Rear wheel\u003c\/li\u003e\n\u003cli\u003eMaterial: Forged magnesium\u003c\/li\u003e\n\u003cli\u003eSpoke design: Six-spoke Cattiva\u003c\/li\u003e\n\u003cli\u003eOrigin: Made in Italy\u003c\/li\u003e\n\u003cli\u003eFitment: BMW M1000RR K66 (2021-2026)\u003c\/li\u003e\n\u003cli\u003eIntended use: Track \/ closed-circuit competition only\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OZ","offers":[{"title":"Gloss Black","offer_id":53167447572746,"sku":null,"price":2193.6,"currency_code":"EUR","in_stock":true},{"title":"Matte Black","offer_id":53167447605514,"sku":null,"price":2193.6,"currency_code":"EUR","in_stock":true},{"title":"Gold","offer_id":53167447638282,"sku":null,"price":2193.6,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/OZCattivaglossy_2f5bc799-313a-43b4-b1fb-119a1149cefa.png?v=1780798025","url":"https:\/\/inter-pace.com\/products\/oz-cattiva-magnesium-rear-wheel-bmw-m1000rr-k66-c6271bm60x","provider":"Inter-Pace","version":"1.0","type":"link"}
