2005 KTM 640 LC4 Adventure

KTM 640 LC4 Adventure

Wherever in the world strange continents, lonely desert expanses or wild jungle trails are explored - the KTM 640 Adventure is the ultimate, single - cylinder travel motorcycle. Directly descended from successful rally racing bikes, it is characterized by its low weight, agile chassis with long suspension travel and a robust LC4 engine.

OIL CIRCUIT

Experience from racing: a second oil injection nozzle now cools the pistons from below too, making the engine even more dependable.

IGNITION

A new ignition program map provides optimized combustion. A "low octane" program map can be activated for low-octane fuel (up to 80 octane).

VALVE TIMING

A new camshaft with quicker valve timing offers a more spontaneous progression of power and even better performance.

FORK FRONT

A new forks set-up with firmer springs reduces the forks' plunge when the Brembo twin discs really grab.

GRAPHICS

There's a new graphic design for all Adventure models in 2005. The KTM letters will be delineated with a silver shadow.

BRAKE REAR

In conjunction with new sintered brake pads, a new Brembo brake disc with round holes guarantees top braking performance and the highest Brembo standard.

INDICATORS

New indicators with a smaller orange glass and a longer operational life.

CHAIN

An X-ring endless chain (without a connecting link) eliminates the risk posed by the weakest link, i.e. the connecting link, which is always subject to the most wear.
