Learn about the lean

Par­al­lel link­age

The par­al­lel link­age con­trols the lean lim­its of the front end, en­sur­ing both wheels stay aligned dur­ing cor­ner­ing, and of­fer­ing up to 45º of lean be­fore it hits its limit (and you scrape the pegs on the floor).

In­de­pen­dent ar­tic­u­la­tion

Twin USD KYB forks are mounted out­side the wheels for max­i­mum lean an­gle, of­fer­ing 110mm of sus­pen­sion travel. They work in­de­pen­dently. Its 41mm front forks pro­vide di­rec­tion set­ting – and hold the wheel and brake as­sem­bly in align­ment. And the 43mm rear forks pro­vide shock ab­sorp­tion, with full preload, com­pres­sion and re­bound ad­just­ment.

Dual front wheels

The Niken uses unique 15in front wheels and specif­i­cally de­vel­oped Bridge­stone tyres to recre­ate the nat­u­ral steer­ing feel of a two-wheeled mo­tor­cy­cle. They help to of­fer high-speed sta­bil­ity, cor­ner­ing con­fi­dence and, Yamaha claims, up to 80% more grip.

What is Ack­er­mann ge­om­e­try?

In sim­ple terms, Ack­er­mann ge­om­e­try means that the in­ner wheel must fol­low a tighter ra­dius than the outer wheel, like on a car. It works to cre­ate a nat­u­ral mo­tor­cy­cle feel­ing in all con­di­tions – by al­low­ing each wheel to in­de­pen­dently track the re­quired ra­dius with­out slip or scrub­bing, en­sur­ing the Niken holds its line and doesn’t drift wide.
