YOu got it Foots. It is a 1300 rear wheel. The only problem with going to the 1800 on the front is you would have to change the front end also. This is the stock front end. The right lower leg had to be shave slightly to accomadate the rotor.
I have an 1800 retro front wheel on my 1300 retro. Fits fine you just need an adapter plate machined so you can use you stock retro and you need custom spacers. I have a pic but the file size is to big. I can send it to someone if they want to post it.
I like that look!!! It looks like a bike that Arnold the Terminator would be riding with a sawed off shot gun strapped to him. I am sure you will get many questions asked....."What kind of bike is that?" VERY COOL!!! Excellent Job :lol:
