    Default Finding a custom tooth count 520 sprocket

    I'm looking for something bigger than a 38T which is stock for the Honda CBR250R 2011-2013. Anyone know how I cross check part numbers? Biggest I can find is a 41T at Vortex....

    Here is the centre numbers for PCD etc:



    Looking for a 43 or 45

    Sprocket Specialties could set you up, but I haven't had great faith in them after the last couple of transactions with them. Good luck salty_monk

    In used to be a dealer for Sprocket Specialists back in the 90's when I had my shop in MA.,they were in Oroville,CA. They have since moved to Utah and none of the pleasant sounding folks seem to be there anymore.I'm also looking for a place for custom steel sprockets.

    I’ve used these guys with success when I was converting my ‘86 GSXR1100 rear wheel to an ‘89 3 spoke 520 pitch. http://www.pbisprockets.com/

    I've more than once bought industrial blank sprockets and machined them to suit.
    530 is a common industrial size and is easily machined to 520.

    Hmm, unfortunate that Sprocket Specialists isn't what they used to be, I always had good luck with them.

    Probably still worth an email inquiry to them.

    Yeah it would be nice if another model Honda had the same PCD/bolt circle & I could get one off the shelf! Anyone know of a good model cross referencing tool?

    Thanks for the links to the custom guys.

    The rear sprockets that I have purchased from them have been beautiful & works of art. It's "customer service" and an "iffy" front sprocket for a GPz that makes me shy away from them. I sent 1 sprocket to them to duplicate & they forgot to return it with my new one. The reply after sever emails was "we're gonna get it in the mail to you tomorrow". To add to the weirdness, I had received it by the time the email response came in???

    Just email SS with the info you have, if there's another model that takes the same sprocket they should know that.
