2021 Suzuki Hayabusa hyperbike has been finally revealed. Nearly 200,000 units later a third generation takes all that was right with the genre-defining hyperbike, but leverages the latest technologies to provide greater control and improved comfort to maintain its position as the ultimate sports bike.
The all-new Busa has the same engine capacity, but loses some power while gaining a huge number of features.
The new Hayabusa uses new, lighter pistons, more rigid and lighter conrods, new camshaft with revised cam profiles to reduce valve lift overlap and new cam chain tensioner, revised crankshaft and crankcases, new gearshift stopper, cam, and cam plate, and gears with revised bearing widths to improve shift feeling, new slipper clutch assembly, and new magneto.
Changes to the combustion chamber promotes faster and more efficient burning of the fuel-air mixture. Further machining on the combustion chamber around the intake valve expands the valve curtain area and improves the flow coefficient by 5% as the valve begins to open and reaches 5mm in lift height.
A new ride-by-wire electronic throttle system works with the new Hayabusa’s variety of electronic control systems, while also providing a light, natural response with linear control, similar to that of conventional throttle operation. In conjunction with the introduction of this new throttle system, the size of the tapered throttle bodies has changed from 44mm to 43mm, but the overall intake pipe length, (including the intake pipe, throttle body, and funnel), is extended by 12mm over the previous intake system. This contributes to producing greater power output at low and mid-range engine speeds.
There’s also a new side feed fuel injector that places the secondary injector at an angle on the side of the intake funnel. Its spray strikes a reflecting plate in the funnel and creates a fine mist that enters the combustion chamber. The result is again an increase in power and torque output at lower engine speeds.
New air intakes reduce pressure loss and increase flow into a larger airbox, which ups capacity from 10.3 to 11.5 litres, and while retaining the bold, twin muffler design the Hayabusa is known for, a new exhaust system saves over 2kg over the previous system, as a new pipe connecting cylinders one and four helps delivery more bottom end torque. A new two-stage catalytic converter replaces the previous single-stage design to help meet Euro5 emissions standards.
Chassis
Suzuki engineers focussed on evolving the existing chassis setup to build on the proven base, as opposed to ringing the changes unnecessarily.
The tried and tested twin-spar aluminium frame uses extruded aluminium sections which lend the right amount of suppleness and strength, achieving a better overall balance. A new subframe reduces weight by 700g.
A new setup of the fully adjustable front and rear suspension units help improve the bike’s stability at speed as well as its ability to turn, and also deliver improved grip from the specially-designed Bridgestone Battlax Hypersport S22 tyres. The seat height is 800mm while ground clearance is quoted at 120mm.
Mounted to new seven-spoke wheels are bigger 320mm discs up front, with improved stopping power also coming from Brembo Stylema calipers.
Longer journeys on the 2021 Suzuki Hayabusa are not only made easier thanks to the extensive electronics package, but changes to the bike’s ergonomics see the ‘bars brought closer to the rider by 12mm, aiding rider comfort while ensuring the rider remains directly connected to the front wheel.
Electronics
The 2021 Suzuki Hayabusa has gained a lot in terms of electronics.
- Suzuki Drive Mode Selector Alpha (SDMS-α) featuring a selection of three factory preset and three user definable modes, combining:
- Motion Track Traction Control System (10 modes plus off)
- Power Mode Selector (three modes)
- Bi-directional Quick Shift System (two modes plus off)
- Anti-lift Control System (10 modes plus off)
- Engine Brake Control System (three modes plus off)
- Active Speed Limiter
- Launch Control System (three modes)
- Emergency Stop Signal
- Suzuki Easy Start System
- Low RPM Assist
- Cruise Control System
- Combined Brake System
- Motion Track Brake System
- Slope Dependent Control System
- Hill Hold Control System
Design & Features
Still low, long, and wide, the new generation has faithfully inherited the DNA of its predecessors, but with sharper lines and a tough, modern look.
The side profile looks every inch Hayabusa, but the design features straighter, sharper lines, from the new mirror design to the famous seat hump. A fresh face comes from new vertically stacked LED headlights, nestled between the new angular air intakes. New position lights flanking the scoops double up as integrated turn signals.
Great effort was also devoted to designing the straight-edged exhaust and mufflers, that sweep up towards the tail.
A colour TFT screen has also been introduced on the 2021 Suzuki Hayabusa – while retaining the elements that standout as Hayabusa: the two large dials that flank the new TFT display.
The large analog tachometer and speedometer gain a fresh, more attractive appearance. Features include bigger, bolder numbering that improves legibility, and raised scale markings around the periphery of each meter use LED lighting to provide a clearer view and faster recognition.
The colour TFT screen displays a plethora of information readouts from the new Hayabusa’s suite of electronics (described in full, below) including the current SDMS-α settings or an active data display that shows lean angle (with peak-hold function), front and rear brake pressure, rate of forward/reverse acceleration and the current accelerator position. The panel also shows clock, gear position, odometer, dual trip meter, ambient temperature, instant fuel consumption, riding range, trip time, average fuel consumption, and voltmeter displays. LEDs located in the corners above and below the LCD include the neutral indicator light, turn-signal indicator lights, high-beam indicator light, low oil pressure warning light, traction control indicator, malfunction indicator lamp, master warning indicator, and ABS indicator. There is also an LED engine coolant temperature indicator light in the upper right corner of the engine coolant temperature gauge and fuel indicator light in the upper left corner of the fuel meter gauge. An ambient light sensor automatically adjusts the instrument cluster’s brightness level based on surrounding conditions, or the rider can also opt to make manual adjustments.
India Launch
The previous Hayabusa was available in India as a CKD at INR 13.75 Lakh. The 2021 Hayabusa is expected to get a price bump and is expected to be launched around – INR 16 Lakh. The 2021 Suzuki Hayabusa will launch in the international market in March 2021 and in India by July-August 2021.
