The third-generation Suzuki Hayabusa, launched as a 2021 model in India at Rs. 16.40 lakh (Ex-showroom), may not be an entirely new motorcycle, but it gets significantly updated from the second generation ‘Busa it replaces. The new Hayabusa gets comprehensive updates for the first time in 13 years. The bike now features improved aerodynamics, as well as an updated electronics suite which features multiple mode selections for each electronic control system to fit different riding conditions, ranging from city riding to touring, racetracks, and to also offer individual rider preferences and skill levels.
The big news on the 2021 Suzuki Hayabusa is the engine, which is said to accelerate more quickly with less peak power. The new Suzuki Hayabusa is powered by a 1,340 cc, four-stroke, fuel-injected, liquid-cooled, DOHC, inline four engine which makes 187 bhp at 9,700 rpm and 150 Nm of peak torque at 7,000 rpm. The new Suzuki Hayabusa sees a 10 bhp drop in power, and now makes 187 bhp at 9,700 rpm, while peak torque has also seen a 5 Nm loss to 150 Nm at 7,000 rpm. Top speed is still rated at 299 kmph, and kerb weight sees a marginal drop of 2 kg to 264 kg.
Although the exterior of the engine remains unchanged, almost all the moving parts have been revised. New cam timing offers reduced valve overlap, and the exhaust valve lift is higher. New valve springs are stiffer to handle the higher exhaust valve lift. New lighter pistons, more rigid and lighter connecting rods, new cam chain tensioner, new quickshifter, and a clutch with assist-and-slipper functions. Fuelling is now ride-by-wire, and there’s a six-axis IMU with a long list of rider aids, as part of the SIRS.
The new Suzuki Intelligent Ride System (S.I.R.S.) features SDMS-a, which offers a choice between three factory presets (A: Active, B: Basic, and C: Comfort), as well as three user-defined settings (U1, U2, U3). Each one of these selects the mode settings as a group for the Power Mode Selector, Motion Track Traction Control, Anti-lift Control, Engine Brake Control and Bi-directional Quick Shift systems. The rider uses switches on the left handlebar to change modes and settings, and the current settings are displayed on the TFT LCD panel located in the center of the instrument cluster, between the Hayabusa's large analog speedometer and tachometer.
