Question: what is the difference between bmw s1000rr and hp4?
Answer: The BMW HP4 (HP stands for High Performance) is the ultimate incarnation of the words sports bike. ... The bike's engine makes 193bhp and has been boosted in its mid-range between 6000rpm and 9750rpm, compared to the standard BMW S1000RR, itself hardly lacking in excitement. But then the weight has been cut too.
