Ya, I actualy found one web page listing the same part numbers, but I remember when I bought them they asked if I had OEM or Heli bars so thats why I'm thinking they may be different. Oh well, I find out when they arive.ConqSoft : I thought they were the same though, only the ones for the Heli-Bars don't come with the internal bar insert like the one for the stock bars does. You could call and ask.
Funny you should ask, I have a throttlemeister (AHR2) on my '99 vfr , and have bought 929 helibars for a project I'm working on - I asked Throttlemeister direct and they said:
"You can use the AHR2 if you are purchasing NEW heli bars. If not you will need some different hardware from us. Cost about $10."
