The Engine and performance Here we come to the heart of the matter – the big 1301cc, 2 cylinder, 4 stroke, V75 degree monster that has been based on the 1190 and the 1290 Super Duke R. Giving out 160 hp that is controlled by the host of electronics. What is more impressive is the fact that you get 140Nm of torque from the machine and even as low as 2,500 revs you’re getting a delivery of 108Nm pulling you away. An absolutely key element in the outstanding performance and smooth response of the 1301 cc 75° V-twin are the unit’s state-of-the-art four-valve cylinder heads. These combine twin plug ignition, flow-optimized ports and a slick, low-friction valve train with cams from each cylinder’s twin overhead camshafts driving DLC-coated cam followers. DLC (Diamond-Like Carbon) is an extremely hard, durable and tribologically (i.e. in terms of sliding behavior) particularly well-suited coating, that KTM uses in many engine parts (cam followers, piston pins, etc.). This is all combined in the slipper clutch; Not only does the slipper clutch open when the engine back- torque becomes too high, it also assists when you open up the throttle. The former prevents destabilising rear wheel chatter when braking sharply or decelerating; the latter reduces the hand force required for changing gear, allowing the clutch to be controlled with the little finger - saving you energy when riding. The 1290 can get a little grumpy if you drop the revs too low and the feel of the bike will be sure to let you know to shift down. There is a massive rev range to play in and she seemed to be very happy sitting at anything from 3k to 9k revs. Given the fact that in the tall 6 th gear override 5k revs will give your around 80mph there is nothing really to complain about. Just keep in mind that you’re on a cruise missile at the end of the day – it’s easy to forget as she is so well behaved when just cruising around. Should you forget, drop a gear and open up to do an overtake the traction control will quickly remind you in safety that you’re riding a mythical monster chained in by KTM technology.
