What difference would going from 110/80/17 to 110/70/17 make?

need new front tyre. Got a sport demon on it at the moment which is a 110 80 17.

KBer has a 110 70 17 for sale. It would fit yes? What would it do to the bike handling wise?

It would fit, and sharpen the steering up, maybe to the point of being twitchy.

But. It depends on how fresh your suspension front and rear is too.

The 110 is how wide it is in mm, and the 80 is how tall the sidewall is as a percentage of the width. the 17 is diameter in inches. Don't ask me why the unit standards are such a mess.

The 110/80 will have a sidewall height of 88mm.

The 110/70 will have a sidewall height of 77mm.

This will do similar things to your handling as dropping the upper and lower triple clamps 11mm down the fork stanchions.

You'll see racers raise the forks through the stanchions to speed up the steering in increments of 2-5mm at a time, so 11mm is a pretty big change by those standards.

thanks for that

From my understnading the current tyre 110/80 sport deamon you have is a sport tourer and if you get the 110/70 it will be a fully sport front tyre which is the right one for yours!

[Posh Tourer :P]

It would also have a flatter profile (ie the curve over the tyre will be less), so deaden the steering too.... not sure if it will make all that much difference to your handling, though it will make some....

close but no cigar ,the aspect ratio i.e the middle measurement is a percentage of the width but is measured from the crown of the tyre to the beading edge not the sidewall

It won't make that much difference Jim...
