Nice bike that '83 Ducati 900 SS but no crotch rocket by horsepower just crotch rocket (look) by way of a road race fairing.

'83 Ducati 900(cc) horsepower was 69.0 hp.

A Suzuki GS850G had 78.0 hp with -50cc less displacement.

A Suzuki GS750(cc) had 84.0 hp with -150cc less displacement.

A Suzuki GS110e had 108 hp with +200cc's

And the 1983 Kawasaki GPZ 1100 had a whopping 120 hp or 51 hp more than the Ducati's hp.

Torque has always mattered more to the Euro and American motorcycle manufactures (HD) but during that time horsepower was king to the American magazines and the J-models delivered that.
