A standard BMW S1000RR with a new £22 rear sprocket and gaffer tape over slots in the screen has come close to cracking 200mph.

The bike had a standard exhaust and no engine modifications whatsoever, and hit 197. 289mph during an experiment by MCN’s sister title Performance Bikes – out today – which explored the bike’s high speed potential.

PB’s editor Matt Wildee said: “To increase the potential top speed, the rear sprocket was swapped for one with two fewer teeth. This yielded 191mph – 2mph more than the bike achieved with the standard sprocket.

It was when the mirrors were removed and the screen slots and gaps around headlights were taped that speeds increased dramatically, with the bike hitting 195.453mph.

When test rider Smith sat further back over the tail, he eventually coaxed out a phenomenal 197.289mph.”
