KTP:The KN wasin 1930 replaced bythe KTP (Twinport). This was a sport bike with two exhaust portsand thus two outlets,but it was not successful.The double gatesyielded a lack ofpower and the ignition coilwas unreliable and thereforedisappeared within a year. TheKTP had thefish tail muffler,which at that timewas modern.
KTS Mk I: The successor to the KTP was theVelocette KTSMk I, which continued until 1935. Remarkably enough this machine was again fitted with an ovalsilencer.The machine had legshields and wide fendersand was thus positioned more as atouring model.
KTS Mk II was produced from 1936 until1940,
