Suzuki Hayabusa 1300cc

    Published on Jan 17, 2010 08:00:00 AM


     Hayabusa is as famous and awkward looking a bike as any

    This new Busa gains a massive 25bhp in peak power output over its predecessor, with 197bhp now spinning out at the crank. The ram air fed, in-line-four, liquid-cooled, four-stroke engine retains its earlier bore dimensions, but has increased stroke by 2mm to 65mm to bump up displacement to 1340cc. Maximum torque is now 15.7kgm developed at 6200rpm.

    The compression ratio is now higher at 12.5:1. A pair of overhead, hollow camshafts power a fleet of 16 titanium and bucket tappet-supported valves. Cam-chain tensioning is hydraulically achieved which helps bring down noise levels. Pistons are lighter and propped up by shot-peened chrome molybdenum steel alloy connecting rods. An advanced digital fuel injection system finds place on the new Hayabusa, as do twin 44mm double-barrel throttle bodies.
    The new Busa uses a curved, compact radiator that is controlled by the bike’s engine management system. This Busa’s six-speed, one-down, five-up shifting transmission is smooth, always precise and positive with oil spray for its top three gears reducing sound levels during high speed cruising. The Hayabusa’s twin exhausts let out a soft, yet menacing exhaust tone that provides a nice background to its silken smooth engine.
    The new Busa’s back torque limiting hydraulically operated clutch is as good as it gets and offers perfect feel.It takes no more than a few moments of experiencing the violence of nearly 200bhp to understand what a Hayabusa is all about. Throttle response is instant with an equator-wide power band starting close to idle.  Once past 7000rpm, there is no letup till slamming into the bus’s stop at 11000rpm.

    No other bike can rocket as quickly from rest with such consummate ease. We managed 0-220kph in 10.26seconds, 0-200kph in 8.39sec, 0-160kph in 5.84sec and 0-100kph in 3.35sec.
    Make no mistake; this is an expert’s motorcycle. It commands respect and should be ridden with utmost care and responsibility.
