990 Adventure
With even more displacement, an electronic fuel injection, regulated catalytic converter and an ABS System, the 990 Adventure is now elevated to the highest technical level in matters of safety and emission control, which is now regulated to conform to EURO III standards. The 990 Adventure is fitted with the proven light weighted LC8 engine with an increased displacement of now 999 cc. In addition, new motor management guarantees a powerful and dynamic unfolding of power and significantly improved torque while maintaining the same level of top performance.

OVERVIEW
Greater performance, even better responsiveness and optimum rideability in all areas these were the objectives KTM engineers set themselves. The result of their efforts not only looks good, it rides particularly well too. The 999 cc drive unit has been perfected in all fundamental details and provides for an enormous increase in performance in the adventure.
CYLINDER HEAD
One important reason for the drastic increase in power from 98 to 106 and 115 hp respectively are the newly developed cylinder heads. Optimisation of the combustion chamber has led to a clear improvement in combustion and rideability in the lower load and RPM range. Ports designed for ideal flow guarantee better charging and therefore increased power. Valves also no longer need to be adjusted during the first service.
CAMSHAFTS
The camshafts have been redesigned specifically for the state for the art cylinder heads. Optimised valve timing has led to improved charge exchange and provides loads of power on all rpm ranges.
CRANK MECHANISM
A new crankshaft with weight optimised con rods reduces the oscillating masses, hence minimising the potential for vibration. The result, powerful, spontaneous responsiveness as well as extremely sporty engine characteristics.
PISTONS
The redeveloped pistons have been produced in an extremely lightweight design. This along with the smaller DLC coated piston pins has led to a further reduction in the oscillating masses and the achievement of extremely spontaneous response characteristics.
ENGINE MANAGEMENT
The proven engine management system from Keihin has been completely readapted to suit the new engine configuration. It regulates the electronic injection system with focus on optimal behaviour under partial loads. Furthermore, a second throttle valve per cylinder ensures as constant a speed torque characteristic as possible, other major system elements are the air/fuel ratio and idle speed control system, cold start automation as well as altitude compensation. All important details in raising the bar to another level in the area of rideability and dynamic response.
MULTIFUNCTIONAL SHAFT
Running centrally between the cylinders, the multifunctional shaft serves as a counterbalance. It acts as a centrifuge for venting the housing, drives both the water pump and the timing chain, and also carries the idle gear for the electric starter.
