CHASSIS The fully adjustable, 48-mm USD forks from WP guarantee excellent damping, incomparable tracking stability and high reserves. The WP shock absorber with an integrated compensation tank is attached by means of a Pro-Lever linkage system and has adjustable rebound damping and spring preload. The front and rear suspension travel is 275 mm. SWINGARM A one-piece, aluminium die-cast swingarm encloses the frame. Its contour was shaped to follow the bending moment curve to provide suspension-assisting flex properties in conjunction with the lowest possible weight. A Pro-Lever linkage gives the shock absorber a progressive pivot point and allows the rear damper to be placed in a low and steeply slanted position to make room for a maximum fuel tank capacity. BRAKES Brembo’s finest Supermoto racing technology guarantees maximum brake performance. Up front, a 320-mm floating disc is teamed with a radially bolted, four-piston fixed caliper and four single linings to ensure excellent application and high reserves. A single-piston caliper and a 240-mm brake disc reliably slow the rear wheel. AIRBOX Nestled within the tubular space frame, the large-volume airbox above the cylinder means high performance and, together with the long intake snorkel, efficient sound absorption. EXHAUST SYSTEM The narrow design of the frame permits a lateral and thereby direct arrangement of the powerful single header pipe, leading from the cylinder straight to the elaborately designed, stainless steel silencer. The large volume of the silencer ensures a minimal noise level, while the regulated catalytic converter oversees the effortless compliance with the EURO III emissions limits. SEAT The sporty and slim seat extends all the way to the steering head and, thanks to its elongated form, offers maximum freedom of movement. A cable noose seat release offers easy access to the airbox and electrics. BODYWORK The rear fender tank and all around new plastic parts give the 690 SMC a completely new, trend-setting appearance, which also clearly displays the clean lines of a KTM-Kiska design. An add-on number plate bracket with indicators and licence plate illumination can be quickly and easily removed for racing use, so that the plate can be mounted directly below the robust LED taillight. FRONT END The flat headlight mask incorporates a weight-reduced headlight with an H4 bulb and a plastic panel with a scratchproof coating. COCKPIT The especially lightweight multifunctional instrument is equipped with an analogue tacho and a digital speedometer, as well as numerous additional functions to provide essential information while you ride. ENGINE The heart of the 690 SMC is its high-tech LC4 engine with 654 cc, which is currently serving as the role-model in the large-capacity, single-cylinder, four-stroke category. It distinguishes itself through state-of-art technology, low weight, compact construction and the highest performance. OHC CYLINDER HEAD An overhead camshaft operates the four valves (extra lightweight, hollow-shafted valves on the exhaust side) by means of two weight- and rigidity-optimized rocker arms. In combination with the compact combustion chamber, this construction makes incomparable performance and the greatest reliability possible, as well as makes servicing simple, due to the slanted attachment of the cylinder head cover. CLUTCH The APTC anti-hopping clutch efficiently prevents the rear wheel from chattering during braking. Under load, the system increases the pressure on the clutch linings, whereby the hardness of the clutch springs and consequently the hand grip strength needed to operate the hydraulic clutch were able to be significantly reduced in comparison with conventional systems. ENGINE MANAGEMENT The LC4 engine is supplied via an electronic injection system, which features a 46-mm throttle plate cross-section, automatic cold start, idle-speed regulator, lambda control and altitude compensation. The so-called EPT System (Electronic Power Throttle) produces a very homogenous power output, because the position of the throttle plate is electronically controlled in addition to the manual operation of the throttle. BALANCER SHAFT A central balancer shaft effectively reduces vibrations to a minimum. |
