Suzuki C 1800 R test

The big C

Suzuki is now building the really large, classic cruiser, the C 1800 R, around the elemental engine of the M 1800 R..

Friends of large-volume, classic-looking cruisers have been poorly served at Suzuki in recent years. The 125 hp M 1800 R power cruiser was the only answer to the competition. Outwardly and in terms of driving experience, however, he was as far removed from a down-to-earth cruiser as the rock brat Avril Lavigne from country singer Johnny Cash musically.

Now Suzuki is closing the gap with the new C 1800 R. However, the sheer, explosive power of the modern four-valve V-engine was slightly reduced. Instead of 125 it is nominally ?? only ?? 113 HP and the gigantic torque was also reduced from 160 to ?? just ?? 155 Nm reduced. In the fourth of five gears, the dynamometer attested 107 hp, plus a maximum torque of 143 Nm. And like Triumph with the Rocket III, Suzuki also limits the torque of its Big Twin in the lower gears (see performance diagram) in order to nip cockiness in the bud.

But no reason to be sad. The C 1800 R has plenty of power and torque. Better still: Your throttle response is nowhere near as rough as in the M variant. She goes on the gas softer, more controllable, more carefree. This is a wonderful way to cruise, especially since the gearbox and final drive also go about their work unobtrusively. But if you want to know, just open the tap. Stomping and shaking at low speeds, the Big Twin makes forwards. Whether in third, fourth or fifth gear? From 50 km / h to well over 200 km / h, the engine pushes forwards with a hammer without pause, as if it wanted to plow the asphalt.

Intoxicating but exhausting. Because beyond 160 km / h, the driver hangs on the protruding handlebars pulled far back like a flag in the wind. And the spongy, soft, comfort-trimmed chassis does not really want to feel at high speed. Slowing down is less stressful, even if the 384 kilogram cruiser needs to be tilted vigorously, the wide tires tend to be sensitive to ruts and draw attention to themselves on bad roads with proper self-steering behavior. The combination brake works very pleasantly and can easily be dosed, easily handling the heavy weight of the cruiser. Its stoppers have nothing in common with the snappy radial brake calipers of the M model. Unfortunately, his wish for an ABS remains unfulfilled.
