All very interesting. Can't argue with the results.
Looking at the tread pattern they appear to both be Pirelli Diablo's?

Funny you should bring this up because although I find the N400 turns in OK and is generally very stable, I have been finding it hard to get right over comfortably for some reason. I was also surprised I hadn't ground my hero knobs once yet. Maybe I need to try the 140 when I buy my next rear hoop.
Thanks for sharing.

Late edit: Your tyre wear pattern looks really good BTW, your suspension set up must be pretty good.
 
I’m a Pirelli guy.

I’m running 120/70 sc1 front
160/60 sc2 rear

Bike handled great with this set up. The rear tire started to tear after about 100 laps but that’s because I’m still in the stock shock and the rear was moving around a bit


Currently have 150+ laps on a 1.7 mile track on these tires
Tyre wear looks good. Interesting that you find the 160 set up good and SDM prefers the 140. Quite a contrast in opinions.

Hey in what way was your rear moving around? I have a similar sounding problem with my SV race bike. It wags it's tail on corner exit under power. tempting to back off when it is bad. Harder you push the worse it gets. Any thoughts?
 
Im using 140/70 I think he is using 160/60. I looked they dont sell it here wanted to see the difference between the tires.
Looking at it on paper I would err towards the 140 because of the quicker turn in and, more importantly on a low HP bike, the lesser unsprung weight of the narrower tyre.
But you cant beat real world testing. :grin:
