ABS protection covers both ends as part of the standard equipment package.ĭual 310 mm disc, Brembo 2-piston sliding axial calipersĢ55 mm disc, Nissin single piston sliding axial caliperĢ022 Triumph Bonneville Bobber Price and Availability Out back, a single-pot Nissin caliper and 255 mm disc take care of business. In spite of the fact that the Bonneville Bobber weighs in at a middling 553 pounds soaking wet, the factory doubled down on the front brakeage with twin-piston anchors that bite dual 310 mm discs. A chunky new 47 mm front forks and a fat 16-inch front hoop matched by a 16-inch rim out back with Avon Cobra hoops make the connection to the concrete. The front end is lent more visual weight. From there, a triangular swing-cage unit continues those old-school lines with an under-seat shock that buoys the rear end for a modern ride in spite of its antique mien. The fall from the steering head to the rear of the backbone is reminiscent of the geometry from the old hardtails. This gives the Bobber rather sharp handling characteristics that give lie to its home-cobbled look. Rake and trail are dead short at 24.5 degrees and 3.6 inches respectively. Welded tubular-steel members a double-downtube/double-cradle arrangement completely cups and supports the engine rather than using the mill as a stressed member. While you can say that the frame sets the stage for every bike, the Bonneville Bobber's bones go far beyond simple support. The Bonneville Bobber top speed is 112 mph (180 km/h). As for the power figures themselves, the Bonneville Bobber generates 76.9 horsepower at 6,100 rpm with a deep torque well at a claimed 78.2 pound-feet of grunt at an even four grand.Ī torque-assist wet clutch couples engine power to the six-speed transmission, which in turn sends power to the rear wheel via a tough chain drive. The fins are mostly decorative though they do carry off some waste heat, no doubt about it. The cooling fins are typical of air-cooled engines, but this plant is actually liquid cooled.
Rather than the old pushrod system, this engine runs with a single over-head cam that times the 8-valve head. The 10-to-1 compression ratio should tolerate mid-grade fuel quite happily.Īnother contrast with its predecessors is in the valvetrain. This gives it a lope at idle and prevents that “angry lawnmower” racket while underway that's so typical of 180-out lumps.īore and stroke are oversquare at 97.6 mm and 80 mm respectively to give the Bonneville its 1,200 cc displacement. Unlike its forebears, this engine rocks a 270-degree firing order.
