When customer Luke arrived with his Suzuki GSX 1400, it was a welcome assignment for Purpose Built Moto’s Tom. More magnificent than this air-cooled XXL in-line four-cylinder from Suzuki is at most the classic in-line six-cylinder from Honda – with which Purpose Built became internationally known in 2021. Client at that time was also Luke.
Slim down and breathe easier
He had used his GSX 1400 for touring in its original condition, but it looked so bland next to the rebuilt CBX that he gave it a treatment at Purpose Built Moto. Workshop manager Tom Gilroy explains his approach as follows: “Slimming the beast and making it easier to breathe will almost inevitably drive better.”
Rear and steering head angle steeper
The original body panels have been removed except for the nice, large petrol tank. The main change was the radical shortening of the rear frame. The remaining solo seat has been given a chic Alcantara upholstery by Timeless Auto Trim. With two longer, adjustable spring struts from YSS, the rear is now a little steeper, which not only looks more aggressive, but also places the steering head angle a little steeper, making handling easier.
Tail with integrated exhaust
The rear has become even more striking with the small tail and integrated exhaust. Soundproofing was obviously not the focus here, so the big four-cylinder shows all the more acoustic presence when it starts roaring. The resistance is also lower at the inlet with the separately attached air filters from DNA, so that with the adapted injection software there are 130 Nm and 107 hp – at the rear wheel. According to Suzuki, it was originally 106 hp at the clutch.
White wheels plus MotoGP colors
The few trim parts were custom-made from sheet aluminum. A relatively small, round LED headlight is located in the lamp mask, which fits closely to the fork, which is supported by an additional light on the left and right. Oil, not water, runs through the radiator hanging in between. Customer Luke had a special request: white wheels. The color concept was coordinated by Pop Bang Classics with silver, blue and black – inspired by earlier Suzuki factory racers.
Seven hours home
Details such as the front wheel cover with brackets or lights and switches including electronics come from the Australian custom bike manufacturer’s in-house product range. When Luke picked up his GSX 1400, he drove it straight home. It took seven hours, though, from the Gold Coast to the New South Wales coast.
Many are beautiful, but also impassable.
Better to leave it in its original state.
Even as an original, the Suzuki GSX 1400 is an impressive sight. This example lost a lot of pounds at Purpose Built Moto in Australia and gained some show effects. Client Luke is happy.
