fatter tires give better grip powering pass the apex. look at the GP rear tires.
for a literbike, it will be safer. but the only question is, will there be enough clearance to prevent rubbing.
i've ridden superbikes with oversized tires. i am able to hammer out of corners without high-siding.
bigger tire = larger contact patch = more rotating mass = readjusting suspension to compensate for new geometry.
the rear end needs to be raised to change geometry. fatter tires will slow the bikes turn in characteristics. either raising the rear or lowering the front will compensate.
extending the swingarm back just changes the whole purpose of the bike.
