KTM 690 Enduro

The KTM 690 series is a range of single cylinder 4-stroke motorcycles made by KTM. The 690’s roots are in the first generation LC4 KTM 600GS from 1987. The follow-on 1994 KTM 620 Duke and the 1997 KTM 620 EGS/Adventure, both 620 models, were actually 609 cm3. 1998 saw both changing their model designation to 640 and introduced the 640 Supermoto with a 625 cm3 motor shared between them. In 2008 the KTM 640 Adventure R was replaced by the KTM 690 Enduro. Also in 2008, the Duke, SMC and Enduro R models were designated 690 even though the actual displacement of the LC4 motor was 654 cm3. In the 2011–2012 timeframe all 690s were increased to 690 cm3.
