On my older R3s, I've fitted 140/75 tyres to the front fit nimbler handling and a Bridgestone 240/55 on the rear for a cheaper tyre. Never had troubles mixing the brands of tyres out changing the sizes

Just don't increase the circumference ratio further (smaller front) or the ABS will fault.
Note: the 150/70R17 is the same circumference as the 140/75R17.
