Nový motor R1 samozřejmě prošel všemi náročnými zátěžovými testy Yamaha a vztahuje se na něj stejná záruka jako na ostatní motocykly Yamaha. Protože až dosud to byly právě otázky životnosti a spolehlivosti, které bránily sériové výrobě takového motoru.
Yamaha R7 2021
Navzdory poněkud svérázné kombinaci rozumné pohonné jednotky se středním výkonem 73,4 k a extrémně agresivního sportovního vzhledu není R7 v žádném případě ovcí ve vlčím rouše. Výkon, který se pohybuje někde mezi R3 a R6, se v praxi ukázal být mnohem silnější, než by napovídaly čisté hodnoty na papíře, a pokud jde o geometrii, podvozek, brzdy a pneumatiky, inženýři Yamahy si dali opravdu záležet. Kromě toho má Yamaha R7 všechny předpoklady k tomu, aby si na kompaktní závodní trati, jako je například Pannoniaring, užila spoustu zábavy hned po vybalení z krabice, a to i bez velkých investic. Ale samozřejmě se lépe cítí na venkovské silnici, a tam podle našeho názoru patří především. Vzhledem k celkovému balení je pořizovací cena více než férově nastavená - takže není problém, že quickshifter není součástí balení a musí se dokoupit jako volitelná výbava.
