I'm new to the page and need some input on a tire conversion. I have an '05 NT and have the stock 150mm on now. I am looking at getting the RSD rear fender kit and running an 18x5.5 spoked wheel with a 200mm rear. I know I will need to get a narrower belt and rear pulley and as far as I know I think an '07's will work. They run skinnier because that year they switched to the factory 200mm. Before I go buying the parts I just wanted to see if any of you have made this conversion. Right now my 05 belt is 1 1/8" and 1 1/2 pulley. Any advice will help.

Here is my build thread on this conversion

Thanks for the info. I am wanting to keep my belt instead of going to a chain. As far as I know I could use the 20mm pulley and 3/4 belt off of an '07 night train. Do you have any input on this? I guess Im not 100% sure that would work, but I am about to order parts and that's what I was going to try. Could you give me any advice on how to make sure the wheel is centered up once the pulley and everything is in place?
Also, I can do all of this with the stock '05 swing arm right?


Im sorry for all the questions! This is just my first big project and I don't want to spend money on parts I don't need. Thanks again for your help

 

I have the rsd 200mm conversion in my fatboy, that being said the belt, swingarm are stock. Just have to cut off the horns on the frame...

 

I did keep my bike belt drive. Machined my wheel down and also machined the backside of the pulley. I converted to the 20mm belt and put over 1000 miles without any belt wear or tacking issues. I thought that info was posted ind build thread. My wheel is from a 09 and so was the pulley. Yes I used my stock 04 swingarm. To keep the wheel centered gonna have to measure center line of the swingarm and then centerline of the wheel.
