2006 KTM 640 LC4 Supermoto
This package combines race-oriented and racing tested technology with the comfort and design of KTM's SMC models. The light, sporty twin exhaust, 11 litre tank and comfortable double seat are the per-fect mixture of agile Supermoto handling with everyday rideablity.
The KTM 625 SMC and 640 LC4 Supermoto have both electric and kick starters; 660 SMC favours the more sporty kick starter.
Smooth shifting and maintenance free hydraulic clutch.
41 KEIHIN flat-slide carburettor with an adjustable accelerator pump and hot start button; throttle position sensor (TPS) conveys the relevant slide position to the ignition's CDI. The 640 LC4 Supermoto features a 40 mm Mikuni constant pressure carburettor also with a TPS.

Compact SAS post oxidises exhaust gases to fulfil strict "EURO II" emis-sions standard.

Double light aluminium silencers derived from KTM factory bikes for high power output and sporty sound.
KTM utilizes a reliable, chrome moly central tube frame, which is very closely related to those of the factory motorcycles.
