Didn't really think you where looking for an answer. One of two possible

1. Cooler air and the bike makes more power
or
2. A few beers and optimistic reading of the speedo.

Beer goggles make the speedo faster, people more beautiful in bars, improves your karaoke voice, and encourages you to dance like Ben Vereen.

Cooler air gives a boost to older bikes that don't have the magic of ECUs. Modern technology takes air temp and altitude into account in providing instructions to your engine. Still, it only works within a range so if you have a choice, go for an optimal temp that is warm enough for tire traction but cool enough for rich oxygen.

As for the ton — it is a rush. Most modern sport bikes get there in less than 8 seconds, but it is a glorious 8 seconds with musical accompaniment by your air intake.

Wow. Correct on both counts. The cooler air is more dense as well.

Yes, cooler air is denser but not as dense as a street rider doing the ton. But that's not using the same unit of measure! :smile:

Earth's orbital speed around the Sun is about 67,000 MPH and takes about a year to complete the trip while spinning at a rotation speed of about 1,037 MPH at the equator, which takes about a day.

All this spinning around isn't fast enough for some people, that's why we have sport bikes. :smile:
