So then you’re running a 100/80 up front and 130/80 on the rear?Regarding the Bridgestones, the BT46s will be smaller than the OEM tires, in the stock sizes, but will put the same amount of rubber on the road when leaned over.
It will increase the speedo error. Mine is now 5mph over. I find that more convenient than the previous 3mph over.
The next sizes up, 110/80 and 140/70, will be about the same overall size as OEM, but will put more rubber down on the sides.
I went with the stock sizes, which is probably why the bike feels so nimble. If you go up in size, do not get 110/90. It will slow down the steering and get very close to the front fender (according to other posters).
