Hi, I have Pirelli Scorpion MT90/AT front and rear on my 950 SE. I normally go 60-70 % tarmac ( No highway, only twisty backroad tarmac) and the rest is gravel/very easy enduro. I also enjoy a track day now and then. The last time I went to a track I was a little to fast/low on a 90 degree turn that ends in a hill ( Slaktern/Rudskogen for Norske lesere :)) The rear just spun out with absolutely no warning, and I got a good ride on my arse with the bike in front of me. ( I'm not a very skilled driver) So to the point: If I change from 140/80-18 to 150/70-18, will this give me a better grip at trackdays without compromising handling on gravel/ligth enduro? Sorry for crappy English and what might be a stupid question.
