Changes promise improved fuel efficiency and an easier ride, writes Craig Duff
SAVAGE cuts to the Suzuki GSX-R600 and 750cc sportsbikes have made the racebred duo better bikes and improved fuel efficiency by a claimed 10 per cent.
The bikes look similar to the existing models, but the 2011 600 weighs a staggering 10kg less than the old unit and tips the scales at 187kg, with the 750 trimmed by 9kg to 190kg.
The changes should mean better performance even without changes to the engine, but it has also been revised to reduce frictional losses.
The fairing is now thinner and uses eight fewer components without sacrificing rider protection or drag coefficient. It covers a lighter and narrower chassis and the wheelbase has been shortened by 15mm for snappier handling.
The tank has been reshaped for easier rider tuck-in and the adjustable map modes now come with two levels instead of three. The instrument panel has been donated by the Gixxer 1000, giving riders a lap timer and programmable shift.
The front suspension is now dealt with by 41mm Showa Big Piston Forks and top-shelf Brembo monobloc, four-piston calipers are matched to a 280mm disc on the front. The reardisc size is down from 188mm to 186mm. Still no talk of ABS on the bikes, but that won’t worry track-day warriors. The engines use the same bore and stroke as the outgoing model, but the internals have been tweaked to cut weight and maximise oil flow. First gear is now slightly taller to match the ratio spread of the other five cogs and the exhaust system uses thinner pipe walls.
Along with the new Gixxers, Suzuki showed its new GSR750. It’s a detuned and de-specced, naked version of the GSX-R750, meaning it will come in as a price fighter and compete with everything from Triumph’s 675cc Street Triple to the Yamaha FZ8 and Kawasaki Z750R. The front forks and rear shocks will only have preload adjustment.
All three bikes should be on sale in Australia in March.
