Aprilia unveiled the latest generation of its Tuono V4 naked bike, boasting a larger 1077cc engine, revamped chassis setup intended to increase agility, and a more powerful electronics suite that now features Bluetooth connection with your smartphone for real-time telemetry and electronics adjustment.
The new Tuono V4 1100 will be available in two versions: the V4 1100 RR, and the Factory APRC edition with Öhlins suspension and steering damper.
A 3mm bore increase (from 78mm to 81mm) is responsible for the 77cc engine displacement boost, with the new pistons sitting on Pankl connecting rods that are a total of 400 grams lighter.
The crankshaft rod journals have been reduced to 36mm in diameter, and the upper half of the engine cases is made with a shell fusion process for less weight and increased strength.
The crankcase also has a ventilation window system to reduce pumping losses.
Horsepower and torque make not unexpected big jumps, with peak horsepower going up five horsepower, but the spread underneath getting a tremendous boost (Aprilia claims an increase of almost 20 horsepower at 8000 rpm compared to the previous Tuono V4).
Engine electronics have undergone some updates, with the third-generation APRC (Aprilia Performance Ride Control) system still featuring eight different ATC (Aprilia Traction Control) settings that are adjustable on the fly using a joystick on the left side of the handlebar, but with more refined operating logic.
The percentage of tire slippage allowed now also differs depending on the speed in the turn: the system's performance is said to be smoother and provides good drive in long sweepers at high speeds without overpowering grip coming out of slow turns.
The AWC (Aprilia Wheelie Control) still comes with three settings, but map 1 (the least intervention) has been recalibrated to be more sporty for better acceleration and a smoother drop of the front wheel when activated.
Both the ALC (Aprilia Launch Control) with three settings for track starts and the AQS (Aprilia Quick Shift) for full-throttle upshifts return unchanged.
Both Tuono V4 1100s now come with the highly advanced Race ABS, utilizing a Bosch 9MP system that weighs only 2 kg and is claimed to provide optimum safety on the street without sacrificing any track performance.
The Race ABS has three levels of adjustment in addition to RLM (Rear wheel Lift-up Mitigation).
Level 1 is for track use, and RLM is disabled; Level 2 is for sport riding on public roads, and the RLM activates progressively depending on the bike’s speed; and Level 3 is for riding surfaces with poor grip.
The Race ABS can also be turned off if desired.
Minor styling changes to the front mini-fairing provide better wind protection and aerodynamics, and the three-headlight assembly is now 1.5 kg lighter.
The seat height is 15mm lower and the tubular handlebar is narrower.
Expected availability for the 2015 Tuono V4 1100 RR and V4 1100 Factory APRC is May 2015.
