Well I just did this upgrade on my Connie, this week. I got a Meanstreak wheel that has been turned down already, and got a Nomad front rotor and bolted it all together. The wheel came with a very lightly used BT-020
http://www.motorcycle-superstore.com/1/28/394/6009/ITEM/Bridgestone-Battlax-BT-020-OEM-Replacement-Rear-Tire.aspx 170/60ZR17. Now I do know that a lower profile tire better for handling, but to be honest with you all, I did not expect this type of improvment. I'm really trying to be subjective but dang I "feel" an improvement.
On the way to work there is a twistie off ramp I need to use, normally I can take the road at a conservative 55-60 mph and maintain it..... any more the rear starts to get unsettled. With this set up 72mph (gps speed) no problem. And she has a better transition too, I think. I now need to get a 17 inch front to complete the package.
Cheers
Ron
