2011 Yamaha YZF-R1, Frame sliders, flush front signals in mint condition! - The 2011 R1…Yamahas technical "Tour de Force." The R1 has been designed to be the "Ultimate Cornering Master" of the open super sport class and one of the keys to incredible handling lies partly in the chassis but equally as important, in its ability to put useable power to the ground. This revolutionary cross-plane crank R1 delivers as much power as the rider wants, exactly when the rider wants it...by a simple twist of the right wrist; leaving the rider feeling like they are directly connected to the rear wheel of the revolutionary R1.
