The Elite 4 on my F6B has sub parr performance. When I first installed them, on the way home from the shop, within less than a kilometre the performance was scary. The front end wandered so much, I thought I had left the front bolts loose. I returned to check it out and all secure. Up to 70 kph the wandering was constant and a highway speeds the wandering stopped. 12000 kms in and a slight improvement was experienced. I replaced with the Bridgestones and noticed a substantial improvement. The wandering is completely gone. The Elite 4s are not recommended for the F6B.
