I wish mine felt nervous! The day after i fitted them i nearly came a cropper on my fave roundabout, turned it in, bike wouldnt lean anymore, went straight towards the kerb!
Yesterday, rode down to the bottom of my road and took a right, the same happened again
The reason I chose renns/SCs is because they offer the rear in a 190/55 which gives the quick steering of a 180 coupled with a bigger contact patch
