Looking to replace OEM tires. I wanted to get some Heidenau K60's, but looking at the tire sizes I'm not sure what I want. I'd like to go to a 150 on the rear, 160 if it will work (although Heidenau doesn't offer that size). Hoping to do 120 on the front but not sure how that will handle. K60 tire sizes available for the stock rim are 140/80-18 and 150/70B-18 for the rear. The 150 is a belted bias tire... anyone running a bias?

For the front the have a 110/80-18 like stock, or a 120/90-18. The 120/90 will be a radius increase of just over 3/4". Not sure that fill fit under the fender without rubbing. Any input would be much appreciated.

Check out the thread above. Send Redbirds a PM regarding the 120/160 combo.

Ha. I knew that would happen. I cruised the threads for a while and didn't see what I wanted so I decided just to post. I knew there had to be a thread out there already. Thanks man.

And not to knock your idea, but keep in mind that one of the main reasons these bikes feel so agile is those comparatively narrow tires. Slapping something wider on there is most likely going to affect that negatively. Coming from sportbikes, I have a great love of nice wide tires, too, but sometimes form just has to follow function.
Just wanted to toss that out there in case you weren't aware - let us know what you do, and how it works out!

Papa speaks wisely.
