Crossplane technology. first pioneered in MotoGP® racing with the M1. puts each piston 90° from the next. with an uneven firing interval of 270°- 180°- 90°- 180°. This uneven order does an amazing thing… it actually lets power build more smoothly. That means smooth roll-on delivery out of the corners. with outstanding tractability. followed by very strong high rpm power. It’s a feeling that’s simply unmatched. like having two engines in one: the low-rpm torquey feel of a twin with the raw. high-rpm power of an inline four. This breakthrough technology on the YZF-R1 represents a paradigm shift in both technology and performance. · Yamaha Chip Controlled Throttle is MotoGP® inspired fly-by-wire technology used to deliver instant throttle response. YCC-I® is Yamaha Chip Controlled Intake which is a variable intake system that broadens the spread of power. The fuel injection system provides optimum air/fuel mixtures for maximum power and smooth throttle response. · The R1 features Yamaha D-MODE (or drive mode) with rider-selectable throttle control maps to program YCC-T performance characteristics for riding conditions. The standard map is designed for optimum overall performance. The “A” mode lets the rider enjoy sportier engine response in the low- to mid-speed range. and the “B” mode offers response that is somewhat less sharp for riding situations that require especially sensitive throttle operation. Switching maps is as easy as pushing a button on the handlebar switch. ALSO SELLINGBrand New: Yoshimura Exhaust System Race Series. R-77 3QTR SS-CF-CF Dual $1. 00. 00. Email me for details. The popular R-77 offers outstanding performance. thanks to being developed in the heat of competition. It features a trapezoidal design. which allows a large volume of packing material and in turn delivers top performance. The R-77 muffler’s front cap is MIG-welded. while the end cap is riveted using high-end 304-L polished stainless steel rivets and bands.
