Today we noticed that in our firestorm the rectifier would overheat within minutes after starting the bike and sitting idle. Looks like we need a replacement. Unfortunately there aren't any to be found. There are Honda CBR600F rectifiers. It would be helpful if someone could confirm if it would work on the VTR.

P.S: The local ad for the CBR rectifier says it supports the following bikes

I have found that most 12v RRs will work on most bikes. My Aprilia RR toasted itself two years ago. An OEM one was $150USD. I scrolled through an online market place for a 12v RR which had the same connectors as mine. I found one for a Honda for $30USD.

When it arrived I had to swap around one wire. It even had the exact shape and mounting holes as my original. It's been in the bike for two years now without a problem. I bought a second one as a back up in case this one failed. The second one is still in it's box in my little workshop.

You could buy the one for the CBR 600 - you might just have to swap out the connectors from your old one to your new one. The fact that it fits so many models tells me that it's generic except for the connectors.

Many years ago my Ducati 860GTe's RR died. None available locally. After talking to a mate who worked in a boat shop, I ended up fitting an Evinrude V6 (I think) outboard's RR - worked fine. I just had to make a little copper heat sink for it.

Thanks, I think I will end up buying the 600 one as there aren't any available locally. Will put an update on how it went.

If you check Flips link - the RR should fit your bike. The Firestorm was also called SuperHawk I believe.

Yes its called the SuperHawk in the US I believe.
I have placed an order on the 600 one as its easier for me. Should be here in a couple of days.
