This might just be our most eclectic Sunday round-up yet. We start with a Guinness World Record-holding 48-cylinder Kawasaki two-stroke, then look at a Royal Enfield Interceptor 650 café racer from Mumbai.

The bike satisfies all legal requirements in England, where it holds a full license. It?s running a one-off engine block with custom fuel and ignition systems, along with a BMW K100 gearbox, and an alternator borrowed from a car. It?s a hefty bi...
