Bonneville America Forums Forums Technical Forums Custom Corner Belt drive question

Hi guys and girls,

I have a question. For my America, I would like to install a Quiet Power Drive belt. I have found this belt on the homepage www.newspeedmaster.com. Their price is relatively high and I am presently trying to find alternatives in Germany.

For this, I require technical data. Who can tell me -

1. how many teeth must the front tire have and how thick/deep does it have to be ?
2. how many teeth must the rear tire have and how thick/deep does it have to be ?
3. how many teeth must the belt itself have and how thick does it have to be ?

I would very much appreciate your replies to my question. Thank you.

Dinqua has done his.

welcome aboard.

QPD is rebuilding their website QPD site , but they used to have the ratios (number of teeth front/rear) posted. I can get the numbers off my belt later, I do rememeber it is a 28.5mm pitch between the teeth though (using the Goodyear Blackhawk belts) , and 135 teeth if I rerember correctly, but I'll get the info later and post what I have.

Hello Dinqua,

I sincerely hope that you haven't gone into hibernation yet, or have you?
When do you think you can post the promised information?
I am very much looking forward to it.

Regards, Korja
P.S. or can someone else perhaps answer the above question? this would be of great help!

I think this is the info you're looking for on Dinqua's site: Belt conversion

First of all, Welcome to the site!
You've come to the right place.

I ordered the QPD belt drive from Brent at newspeedmaster.com
last week. It is on back-order.
Hopefully it will arrive before the NorEast Rally, so I can
ask(bribe) Pat for help putting it on. His website has a
great section on installation, but I'd rather do it under
the supervision of someone that's done it before (and someone
who I consider an expert on these bikes).

I agree it's expensive, but I'm convinced it'll be worth it.

Progress reports to follow,
Uncle Charlie
