Based on what I see in the parts list (web) all 2015 LEs (600,900,1200) have M3 x 30mm pins. So this is great and easy to do. 1/8" punch is all you need and you can punch them right through.
+1 ; 1/8" standard punch worked great from me 2017 Rene 600ETEC. Didn't need to use the roll pin punch or find a 3mm punch. Replaced the pivot bolt with the earlier design with the clip, I just looked up the part number from an earlier model year. I was expecting removing the pin to be a b**th, had I known how easy it was i wouldn't have bothered making the switch but I purchased the parts and so just went ahead.
