As I'm mulling over the addition of a BB kit to my new purchase, the thought occurred about the increase in top speed and how close to the speed rating of the tires one would see. Those of you with the bird, are the tires rated up to a certain speed? And what would be a likely top end for a 1700? (Not that I want to see it, just curious, ya know.)

Not sure what the OEM tire ratings are but I have a set of Pirelli Night Dragons setting here as replacements (when needed) that are Z rated. That should cover it.

The rear is a 200/55-17 instead of a 200/50-17.

The stock metz's are Z rated i believe.

I thought I read somewhere that due to how ABS works on a bike it was not advisable to change the tire sizes....was I dreaming?

"On ABS-equipped vehicles, all vehicle manufacturers recommend using the same size and aspect ratio tire as the original. ABS systems monitor the rotational speed of the tires through individual wheel speed sensors. Changing to an oversize tire with a taller diameter than stock would cause the tires to rotate at a slightly slower speed relative to vehicle speed than the stock tires. Changing to a low profile tire with a shorter diameter would cause the tires to rotate at a slightly faster speed relative to vehicle speed. Though the difference either way isn't much, it may be enough to upset the calibration of the ABS system and have an adverse effect on its ability to detect and prevent skids."
