1972 Suzuki GT 750 J (739cc  water-cooled two-stroke transverse triple)

 

67 bhp, 482 lbs, 123 mph

 

Launched in late 1971, this was Suzuki's answer to the changes being brought to the motorcycle industry, mainly by the Honda Four. It built on Suzuki's extensive two-stroke background but was radical in being the first large capacity water-cooled two stroke. With a five speed gearbox, electric start and solid performance it held its own versus the other large capacity bikes of the period. Its wet weight (with fuel, coolant and oils) of around 550lbs, resulted in something of a handling - and manhandling - disadvantage (not easy to get on its centre stand).

 

For the first model year (1972), the GT750J, had a double-sided, twin-leading shoe, 200 mm drum front brake with 180 mm drum rear. The Exhaust Coupler Tube System (ECTS) that connected the left- and right-side exhausts together was designed to boost low-end torque. Carburetors were 32 mm Mikuni slide type and power output was 67 bhp at 6,500 rpm. Also included was Suzuki's SRIS (SuzukiRecycle Injection System) which was a method for lowering the visible exhaust smoke by collecting and burning residual oil/gas lying in the bottom of the crank chambers. This was a first for any two-stroke from any manufacturer.

 

The GT 750 was produced till 1977, but then - as with most two-strokes - fell victim to rising emission controls.

 

This bike was acquired in the UK in 2013, but spent its life in the US Midwest. It is original in every respect, including original paint (California Burgundy or Candy Lavender - Suzuki colour code 216 - and Pure White - Suzuki colour code 64), vented side covers, black cone exhaust tips and painted radiator end covers - plus the front brake as mentioned above. Relatively minor restoration and tuning work has been undertaken.
