After riding the 2015 Yamaha R-1 one will be totally amazed!!!! The 998cc crossplane-concept inline-four is essentially all new and weighs 8.8 pounds less than the engine it replaces. Titanium fracture-split connecting rods are 60 percent lighter than their steel counterparts; the cylinder head now has finger-follower valve actuation (permitting increased lift), larger-diameter intake and exhaust valves, and revised cam timing; cylinder bore has increased to 79.0mm (up from 78.0), while stroke now measures 50.9 (was 52.2); compression has been bumped to 13.0:1 (from 12.7). Thanks to the new valve gear, lighter rods, and shorter stroke, redline has been raised from 13,750 rpm on the previous model to 14,500 on the 2015. Allowing the rider to control the increased power output is Yamaha’s proprietary six-axis inertial-measurement unit (IMU), which measures pitch, roll, yaw, and acceleration fore and aft, up and down, and side to side. It then feeds all of this data to the Yamaha Ride Control processor that meters Power Delivery, Traction Control, Slide Control, Lift Control, Launch Control, and the Quick Shifter. Settings are controlled via an all-new and excellent TFT display interface. MENU: All of the bike's electronics settings are accessed via the Menu thumbwheel on the right control pod. Odo, Trip-1, Trip-2, Fuel Consumed, Fuel AVG, CRNT Fuel (average), engine temp, and air temp. The chassis was completely updated, as well. An all-new aluminum Deltabox frame with magnesium subframe contributed to lowering the R1’s weight dramatically (we measured a 34-pound reduction for the bike, sans fuel). Wheelbase has been reduced by 0.39 inch, all-new suspension (manually adjustable KYB on the standard model tested here) is included, it has new brakes with ABS and the Unified Braking System (UBS, with linked functionality), and it has 10-spoke cast-magnesium wheels. This one also has a "M4" pipe that has been installed, WOW, talk about a SWEET Sound!!! 172.8 rear-wheel horsepower at 12,270 rpm, with 77.0 pound-feet of peak torque at 8,810 rpm. Now that will get you down the road!!! Some bikes you just hop on and click right into position, This in one of those sportbikes!!! Bars, seat, footpegs, control feel all felt completely natural and are beautifully placed. What Yamaha has done better than any other manufacturer thus far is to keep the electronic intervention in the background and let the rider just focus on staying between the lines. The user interface is intuitive, the chassis predictable and stable, and the build quality is of the highest order. Fully serviced, and we have installed new tires on it too!! This bike is Amazing!!!
