2016 KTM 690 Duke

Owners for 2016 and 2017 model year KTM 690 Duke motorcycles should take note, as the National Highway Traffic Safety Administration (NHTSA) has issued a recall on the popular hooligan machine because it may leak fuel from its filler cap on the fuel tank.

The recall affects 718 units in the United States, but in documents to NHTSA, KTM says at this time it does not have a remedy for the problem, and that such a remedy could take up to 120 days to create.

Presumably, this would then bar KTM from selling any 690 Duke models in the United States until a fix can be made.

The KTM 690 Duke has always been a fun street bike, with a fair amount of power wedged into a relatively light package. For 2016, the KTM 690 Duke learns some refinement though, most notably with an engine overhaul that drops the buzz from the motor, and adds power to the dyno chart.

This comes about as the 690cc LC4 engine gains a secondary balancing shaft, a new crankshaft, and lighter pistons and connecting rods. All these changes come with a new cylinder head that has the exhaust valves on roller rockers, and the intake valves on the camshaft.

The result is that the 2016 KTM 690 Duke gets a modest power gain – a 73hp peak horsepower figure – and a powerband that is 1,000 rpm wider than before.

KTM is pulling the interesting move of only alerting certain outlets to the fact that the Austrian company will be bringing updates to the KTM 690 Duke for the 2016 model year. Regardless of that alienating choice, the facts remain, and we’re here to give you the details of their new models.

As such, expect to see the 2016 KTM 690 Duke to get a power boost, roughly to the tune of 73hp @ 8,500 rpm (up 1,000 rpm over the previous model), with peak torque also getting a boost of roughly 6%.

This increase in power comes about partly to internal changes, which include a larger bore and shorter stroke. These give that 690 Duke a very slight displacement increase of 3cc, for 693cc in total.
