Tyre wear question?
 
I noticed that the front tyre looks more scrubbed than the rear over near the edges, also i'm nearer to the edges on the front than the rear.

Pirelli 120/70 and180/55.

35psi and39psi.

Could it be the front damping or preload is too hard?

cheers

Braking deep into corners?

I'm not that quick, maybe I don't know i'm doing it?

is the bike understeering.
sounds like it must be
as the back is pushing the front when cranked over
raise the rear or lower the front

I would say thats nomal,if you fit a 190 on the rear then you would see the front closer to the edge as its a 180 and has a smaller profile the front does'nt get such a hammering in the corners. Thats my experiance between the two as Ive just gone back to a 180 from a 190. 4D

It is a 180 so i'm not sure what you mean 4D

I have dropped the forks through the yokes, or raised the yokes up the forks if you prefer so yes the front is higher than it was when I got it, i'll change it back or lift the rear.

Is this the result of what people mean when they say "pushing the front"?

Thanks all.

"Pushing the front" thats when you go into a corner a bit too hot/fast and still be on the front brake ,your'e then "pushing the front" tyre to its limit of adession and a possible spill.
The 180 is the width of the rear tyre (180mm) with a 180 on the rear your front tyre will turn quicker into a corner and lean over in comparison to the width of the rear tyre thus the "Chicken" strip ( where the tyre has not been used)will be wider, but closer to the edge on the rear
With a 190 mm rear tyre because its wider you find the front is slower to turn in and will wear nearer to the edge , as you are trying to overcome the extra width of the rear . Sounds complicated you need to see it more than talk about it. Hope that makes sense 4D
