Honda VFR 750 vs CBR 600 F4 

cbr600 stronger top end and around 10 more hp in the bag. The f4 also has around 10 years of engineering advancement on the VFR. However I personally prefer the VFR; have a soft spot for them, the awesome V4 power plant with gear driven cam whine and that lovely single sided rear swingarm etc.

Yes exactly, it is much harder to get a good start on cbr, cause of lower torque on low rpm, but at high rpm it feels much faster than vfr

Yes definitely, if we keep going he flies by me when i hit about 120mph
