New tire, chain and guard...
 

It's strangely fun to modify bikes that weren't designed to support such features...

For instance it took a little grinding to fit my new 160 ContiForce rear tire setup into the swingarm by removing the stock chain guide bracket. THEN the old worn chain which ate into my precious Excel Rims got replaced along with an upper chain guard which hopefully will prevent more rim destruction. The tire however is so wide(missing the edges of the swingarm by millimeters) will inevitably get rubbed, but so is the case with most converted motards.

Now the tire will protect the rim from the chain.

For like 5minutes maybe, I wish I had pics of the Dunlop slick that was on it. The whole left sidewall was ate away down to bead just about.(hence all the markings on the rim)

The rim looks sorta cool like that. Is there anything you can do to stop the chain from rubbing?

Why put a 160 on such a small bike? I mean, obviously a 110/100-18 is a weird size, but something that doesn't destroy tires and rims would be better, right?

You could shim the whole chain system outward with some SS washers behind the sprockets.

Ya the guard sitting atop the swingarm blocks the chain from the rim. It would the tire as well but its a bigger tire. A 150 wouldn't come close.

For better traction and as much surface area for a contact patch as possible. The previous tire was a 170/65 dunlop slick. The previous bike owner bought the 160 n threw it in the deal with the bike. However he didnt calculate the correct size tire, but luckily I got it to fit. BTW my wheels are the standard 17" sportbike size, the rear is only about 5" wide similar to a ninja 250 or even an SV.
