THE Duke is the foundation of KTM’s road range. It’s the bike that took the Austrian manufacturer from the dirt to the road, laid the groundwork for its range of road bikes and is a shining example of KTM’s commitment to single-cylinder engines.
Now in its third generation, the new 690 Duke is the latest affirmation of that commitment. For 2016 the new LC4 engine has been heavily reworked from top to bottom. The new cylinder head houses a redesigned valve train that incorporates an additional balancer shaft. The bore has been enlarged by 3mm, while the stroke has been decreased accordingly. The crankshaft, con rod and piston are new too.
