Nah... it's just how we ride these dam fine bikes....
I have a 125 Criuser, and used the bake brake on that more than the front. Worryingly that was a drum on the back...On the rider course it was a sports tourer style and was braking 'properly'... Get on the America and back to using the back brake more.
And then I've had a warped rotor on the front for a couple of weeks so haen't really used the front at all. Then the back pad looked really worn, so engine braking became the norm...

However now have a brand new front rotor and new pads on the back. So I will have to get used to a normalformebrakemethod again.
