While the previous iteration of the R1 was designed with more of a street focus, this new R1 is all about taking it back to the track. The new R1 comes with an absolutely incredible electronics package assuming the deliverables meet the claims. The new Communication Control Unit Rider Machine Interface System is composed of a GPS antenna and data logger which measures and records things like engine rpm, throttle position, speed, fuel consumption, braking pressure, and coolant temperature, while also recording your physical position and track times.

The setting Traction Control System TCS calculates and manages the speed differential between the front and rear wheel while taking lean angle into account. All of these systems are how you keep from exploding into flames.

The R1’s Deltabox frame is all new, composed of aluminum, and makes for a 10 mm overall shorter wheelbase. He idea being you can have them correlate directly 50 percent open gives you 50 percent throttle or some variation of more throttle at a smaller opening race settings or less throttle at a larger opening low-traction conditions.

Yamaha hasn’t released power figures yet, but rumors put it north of horsepower. Yes, I know that was a lot, and no, we’re not done yet. All of these systems are how you keep from exploding into flames.

Unfortunately, the Yamaha types would only respond to such questions with an enigmatic grin Share 0 Join the Discussion.
Finally, the three-setting Quick Shift System QSS detects movement in the shifter to briefly cut engine output for upshifts without the rider having to use the clutch or close the throttle. Yamaha claims the UBS system works with information from the Inertial Measurement Unit to help dictate how much rear brake is applied, based on the lean angle and available traction. It comes with three pre-set levels of intervention, as well as three rider presets, allowing for further customization for rider preference.
The cc engine is all new, though it still uses the inline four-cylinder cross-plane crankshaft model.

The IMU system is part of what helps tell electronic rider aids what to do. With World Superbike rules increasingly limiting the modifications that can be made to the streetbikes that the racebikes are based on, we had to ask if the up-spec R1M was really developed to put Yamaha back at the front of the World Superbike grid. Yamaha confirms new R1 for with teaser video Sean MacDonald. Street mode shows you your more common data points, such as speed, revs, and odometer, while track mode focuses more on lap times, best lap, and last lap, etc.
The four-setting Lift Control System LIF measures the front-to-rear pitching rate and helps keep the front end down under hard acceleration. The wheels are now magnesium, as is the new subframe, which shaves 1. The Ohlins Electronic Racing Suspension system takes information from the Inertial Measurement Unit IMU times per second and then controls the front and rear compression and rebound damping accordingly.
Three-setting Launch Control System LCS limits the engine to 10, rpm while the bike is at standstill, even with the throttle wide open, and makes sure the engine output is at optimum levels in conjunction with the TCS and LIF systems.
The fuel tank is aluminum too, which Yamaha claims is 3. Power Mode PWR is the R1’s version of fuel maps, which allow the rider to choose between four different settings that modify the throttle valve opening rate based on the degree the throttle grip is open. The setting Traction Control System TCS calculates and manages the speed differential between the front and rear wheel while taking lean angle into account.
Yamaha is pulling no punches about making its flagship, liter-class sportbike a serious track weapon, not an all-purpose machine. The front suspension is now adjustable for preload, rebound, and compression from the top of the KYB 43 mm fork, and the KYB rear shock allows for preload adjustments, as well as compression and rebound adjustments for both high and low speeds.
Subscribe to The Common Tread. The entire Yamaha Ride Control System has four customizeable presets, allowing the user to set each system specifically in each varying preset, allowing for four totally customizable electronic rider setups.
You’ll have to bear with me through all of the acronyms and names a bit, but I think you’ll like what they’ve come up with. Overall, the new engine is nine pounds lighter than the previous model, and an inch and a half narrower at the crank.
