Edited Date/Time:
I have been using a starcross 5 soft 80/100-21 front and 110/100-18 rear on my 1980 yz250 and riding tracks with a dry, hard, surface like milestone, perris, and elsinore. I just got a 1981 yz 465 and it has a fairly steep steering angle, so it turns pretty decently, so i was considering going with the larger 90/100-21" starcross front in hopes that it would give slightly better traction on flat, hard, dry surfaces then the 80/100-21", but wanted to know if it will make it noticeably harder to turn or lean or if it will try to climb out of ruts etc with the larger tire. Appreciate any opinions on this from those that have run a 90/100-21" front tire on mx type tracks.
I plan on using the starcross soft or hoosier 25 compound (semi soft) rear in a 120 so i can get the beast to hook up at least a little.
Thanks in advance for any opinions/suggestions.
