Default Belt to chain conversion question

Hi all,

I'm going to do my first belt to chain conversion on my 2003 - 883 Hugger, since it is the first time I''m doing this I was wondering if any one now how I can calculate the size of the sprockets. I
want the same gear ratio as with the belt drive .

Thanks.

mmesa005 thanks for useful links,

Thanks to the link I now that I need a 23 tooth at the front and a 48 tooth at the rear, I am now looking for a shop based in Europe because the tax that I pay with when
I import it from the US is approx 40% on the total including shipping. There are several shop that sells the Lowbrow brand so I'll contact them.

I also forgot to say that I use a 200 rear tire and need a offset at the front so it will fit for this setup.

I think my stock sprockets are 23/48 on my 1991. I would highly recommend an X-ring chain and use Bel Ray Super Clean Chain Lube. I have an RK X ring but there are other quality manufacturers as well. The Bel Ray lube does not make a mess on your back rim or swingarm, amazing stuff. And, my X ring chain has needed no adjustment in almost 4000 miles, that's so much better than previous chains I've used. Get a good chain, don't be a cheap bastid. I think I used a 106 link chain, but don't hold me to that.

Hi John,

Thanks for the advice and tips !

My frame is about 3" stretched so I think the chain have to be a bit longer then yours if your setup is stock. I'm going to start with ordering the sprockets and then I can measure the chain lenght,
Or with the length in mind that you give up, I choose one with the extra length of the stretch. If the price does not make much difference, I better choose one more then long enough and that
saves shipping costs if I can order it al together.

He's right, my 1991 stock sprockets are 48/21. They did not have chains on 1991 1200s, only "newfangled" belts. Only 883 Standard models had chains.

Madnss thanks for your input !

On road6customs website they say 23/48 to get a allround perfect ratio but I prefer the ratio from someone who experienced them selve and mine is also a 883.
In the euro webshops that I have searched in today, I also found more 21 and 22 tooth sprockets and in many more offset sizes.
