Thanks I'll be ordering that kicker soon . The stock kicker feels wrong and looks weird at least to me, looking forward to trying the RGM kicker .Yes, it's the RGM one as stated by others. I bought it for my Dommie Cafe Racer but it didn't work with the rear sets so I fitted it to the Commando.
The downside to this kickstart is that it's quite a high reach up for the foot for a kick when sat astride the bike for me (32 inch inside leg).
Bonus now I know of another source for parts your post is the first I've seen mention RGM so thanks again!
