After checking the Kaoko website for the correct model and it showing HND310 I bought a throttle lock second hand from his now sold CT, but it won't go in as the inside of my bars are threaded for the OEM bar ends and the throttle lock looks designed for a smooth inside tube. I have a late model 2018 DCT CT. There appears to be another model mentioned on this forum of HND200, but wondered if anyone else has had a similar issue?
