Suzuki launched the highly anticipated 2011 model GSR750 in Australia on Tuesday.

Suzuki Motorcycles launched two brand new models to the 2011 line-up in Melbourne this afternoon, including the highly anticipated GSR750 and a TU250X retro bike.

Both models will be on display at this weekend’s opening round of the World and Australian Superbike Championships at Phillip Island, however the pair was introduced today to the national media.

The GSR750 will replace the existing GSR600 when it’s released in autumn (May or June), its price yet to be confirmed in Australia.

An all-new aggressive street fighter set to shake up the big bore naked bike category, the GSR750 features an engine based from the K3-K5 model GSX-R750 sportsbike.

“We have been looking forward to the arrival of the GSR750 as it provides riders with an aggressive naked Suzuki street bike option,” said Perry Morison, general manager motorcycles, Suzuki Australia.

The GSR750, which was first previewed in an artist impression during Intermot 2010, features a 749cc, four-cylinder, fuel-injected DOHC engine resulting in broad powerband with loads of low-end torque and dynamic mid-range power.

The fuel-injected motor from the K3-K5 model GSX-R was selected for the shape of its cases, providing a suitable position for the street fighter chassis.

A broad torque curve was the focus of the development, featuring revised ports and an increased piston pin size in comparison with the GSX-R. The conrod is also shorter, but stronger.

“It makes sense to take that legendary GSX-R750 and make a naked bike out of it in the GSR750,” Morrison added. “We are very confident in its position in the market place.”

Providing impressive stopping power, the GSR750 is fitted with 310mm dual front disc brakes and a 240mm rear disc brake.

A sculpted vented front fender and headlight shell and chiselled aggressive front bodywork complete its head-turning looks.

The GSR750 instrument cluster has been designed with functionality in mind.

In addition to an analogue tachometer, the LCD display features a digital speedometer, gear-position indicator, temperature gauge, fuel gauge, clock and selectable odometer/dual-tripmeter. It features a 17-litre fuel tank.

Gold coloured anodized upper tubes on the inverted KYB front forks and exposed four-into-one exhaust system highlight the GSR750’s styling. Plus, Bridgestone BT016 tyres are fitted standard.

The Suzuki GSR750 comes in a choice of two colour schemes – Glass Sparkle Black/Pearl Mira Red or Pearl Glacier White – and is backed by Suzuki’s two-year, unlimited kilometre warranty.

According to Suzuki, pricing information will be announced closer to the arrival date.

Suzuki revealed that it will bring the TU250X into Australia, arriving in April for $5990.

Another new street bike to Suzuki’s line-up is the Suzuki TU250X, arriving in Australia this April for $5990.

The Suzuki TU250X is perfect for riders seeking a retro looking, user-friendly motorcycle, packed with proven Suzuki reliability and high-quality features.

According to Suzuki, the TU250X will fill a void in the Suzuki line-up between sports, cruisers and scooters – a motorcycle that has proven popular in overseas markets.

“The Suzuki TU250X is the ideal motorcycle for a wide range of riders who are seeking a timeless and classic machine,” Morrison explained.

“We’ve complemented our range with a retro looking, value packed bike with broad appeal. The TU250X has proved very popular in other markets and I am pleased that we could introduce it into Australia.”

Delivering a responsive and easy-going ride, the Suzuki TU250X’s 249cc, single-cylinder, fuel-injected, air-oil cooled SOHC engine produces strong low rpm torque, making it ideal for the city rider.

The TU250X’s digitally controlled CDI ignition system provides optimum ignition timing and engine speed, with its five-speed transmission making it ideal for variety of riding conditions.

The front disc brake with dual-piston caliper and rear drum brake combine to give the TU250X impressive and reliable stopping power.

Suspension is made up of a telescopic, coil spring, oil damped fork at the front-end, while dual swingarm-type, coil sprint, oil damped shock absorbers are featured at the rear.

The TU250X’s generous 12-litre fuel tank and fuel-efficient engine work together to provide excellent fuel economy and riding range.

An ideal choice for a variety of riders, the TU250X has been designed around a strong diamond-shaped steel frame with a low seat height, compact chassis and upright riding position.

With classic retro styling, the TU250X displays chromed front and rear wheels, headlight case, speedometer cover, tail light housing and exhaust system.

The Suzuki TU250X will be available in a Pearl Black/Metallic Grey colour scheme, backed by Suzuki’s two-year, unlimited-kilometre warranty.
