Or it may be that your riding on "small" tracks, the tracks I ride are both about 2.5 miles with corner speeds from around 40 mph to a little over 90 mph. Could also be your riding style, I am normally at or close to full throttle from the apex on.
front has a little left to go
rear is at the edge, but has never let go on a clean track

You can see that 110 front tyre has taken more load (probably from trail-braking).
than 140 rear tyre, which has more even and less loaded wear.
With my more lopsided 110/150 Alpha 13-SP combo, due to Dunlop dealer monopoly refusing to sell me 130 or 140 rears, front tyre is easily overloaded. At limit, it's cooked and overheated all way to edge. Balls on edge is rubber that's scraped from centre to edge as tyre is sliding. It's so hot it even picks up bits and pieces off track on way back to pits!
Meanwhile rear 150 tyre is much calmer and cooler. Even with double Ninjette's power, I can't break rear-end loose when leaned over. Gently rolling on throttle or whacking it open just causes smaller front-tyre to slide; back-end glued securely in place.
I'm going down to 140 rear next and may even get 3.5" front wheel to run 120 tyre.
