The 2012 Yamaha YZF-R1 has broken cover, and the biggest feature the lightly tweaked liter-class bike boasts is a new seven-level traction control system (for our brothers in arms across the pond, a six-level traction system is being used…consider that punishment for your European ways). Other material changes include a revised engine map for smoother power delivery in the lower and middle rpms, while the footrests, triple clamps, headlight marker lamps, front cowl, and exhaust guards & end caps have also been revamped for 2012. More after the jump.
