The final effect of the machine's power characteristics is an average fuel consumption of a consistent 41 mpg, which is a ridiculously high rate for a 250 and comparable to the consumption of a heavyweight performer. But the poor fuel mileage reflects the fact that you have to use lots of revs to obtain the engine's full performance and anything less is not going to get you very far. However, lighter riders should be able to improve upon my fuel figure by 3 or 4 mpg. The petrol tanks holds 3.3 gallons, and goes on reserve at about 105 miles, at which point it takes 2.75 gallons to fill to the brim. Two-stroke oil consumption is meagre at almost 300 miles to the pint, a tribute to Suzuki's excellent CCI lubrication system. | The final effect of the machine's power characteristics is an average fuel consumption of a consistent 41 mpg, which is a ridiculously high rate for a 250 and comparable to the consumption of a heavyweight performer.

The engine is conventional for a modern two-stroke, with twin | The engine is conventional for a modern two-stroke, with twin aluminium alloy cylinders having four scavenging ports, which gives a power boost over the old GT250M model's twin ports. Unlike the older model the cylinder head is a single casting, and does without the M model's ram air cover which was of dubious value. The crankshaft runs on four main bearings; the centre pair and the left bearing are lubricated by the CCI oil supply, and the transmission oil does the honors for the right-hand bearing. The air cleaner is a wet polyurethane foam element, replacing the M model's paper type, and the carburetors have revised jetting as well as being mounted on flexible rubber inlet pipes. The six-speed gearbox is smooth and combines with a light clutch to give easy changes, although shifting through the lower ratios is a bit noisy. The transmission oil, all 2.3 pints of it, is easily accessible for filling and draining. | ||
All this makes for an undeniably rapid 250, and the engine's performance is not let down in the handling and braking departments. The brakes really are first class, the front hydraulic disc giving progressive and powerful retardation which is well supported by the cable-operated rear drum. A lightweight needs no better brakes than these. Despite what goes down in my book as our worst summer in years, it never rained during the test so I have no idea how the disc performs in wet weather. The stop light is activated only by the rear brake, although provision is made for a front brake light to be fitted — in today's traffic it should be standard. | All this makes for an undeniably rapid 250, and the engine's performance is not let down in the handling and braking departments.
