Thread: Yamaha YZF-R1

When Yamaha first brought in its fly-by-wire throttle method named YCC-T in 2006 on the YZF-R6 and then after one year on the R1, many wondered if the method was a material to traction control on Team Blue’s Super bike. As this years rolled on it expected similar to Yamaha was more than fulfilled with the power send to the R1, and to be sincere we were also once the crossplane crankshaft engine constructed was insert into production. The link among the rider’s right wrist and the rear wheel on the cross plane crankshaft skilled sport bike has been almost telepathic. It almost looked that traction control would be redundant with so much throttle control in build. Yet for 2012, Yamaha has skilled the R1 with traction control. Is it a gimmick to maintain the R1 at the top of the sales for sport bikes in 2012, or will it create an excellent road bike and racer?


To search out, we were received out to a Southern California desert hotspot familiar as Indian Wells to expenditure two days riding the 2012 YZF-R1 on the road and track. One day would assume us up a part of the twisted Palms to Pines Scenic Byway and return in near tri digit heat. For the second and more expected day, we would proceed to the always famous Chuckwalla Valley Raceway. Both days would give us lot of time and varied times to play with the new electronic wizardry from Yamaha.




The list of alters to the 2012 YZF-R1 can be counted on one hand, but only one of those 5 alters is sufficient to acquire our attention. The entire latest 7-place traction control system is derived from seasons of competition in MotoGP with the YZF-M1. Using tyre speed sensors and a latest ECU, the TC system first observe tyre spin through calculation the difference among the rotational speed of the front and rear tyre. Once slip is observed the ECU set the YCC-T, fuel injection and ignition to optimize tyre spin and forward drive. Yamaha arrogates that the the system will observe a loss of traction early the rider can and search the excellent collection of throttle opening, fuel delivery and ignition to make a so smooth and seamless power management answer. Through varying the throttle opening, the system avoids a jerky or harsh experience when the power requires to be handled. The math is complicated but the system is pretty straightforward.


The seven place of the traction hold back system are 6 increasing steps of intervention and the option to switch it off fully are controlled through a switch on the left device. On the fly alter just need a shut throttle, but to switch the system off the motorcycle must be at a stop. A bar graph at the top right of the LCD dash shows what level is chose and a yellow light flashes when the TC kicks in. Mixing those 7 options with the 3 levels of the D-Mode power selection gives the rider 21 circumstances to well tune the ride.
