Well those numbers people are pulling are by pro drivers so are the numbers from sport rider are pro riders.

And they even factor in bull**** math crap for altitude temp wind etc to make the time slower. Let's say a bike pulls a 12.3 after all there mumbo BS it turns into a 12.8 sometimes.

 

Those numbers arent mumbo BS or anything else. If you know much about engines, whether car or bike, you will know that altitude, head/tailwind, barometric pressure, and temperature have huge factors on performance. For instance, I have a 1969 olds. At 500 foot elevation, the car runs high 12s low thirteens. At sea level tracks the car runs low to mid 12s.

They have to add the math factor in, or else everyone would have to test at the exact same track on the exact same day.

BTW, 13 second quarter mile is a lot faster than you think. 1 second means a lot when it comes to the quarter mile. For bikes to be able to do it in 10-11 seconds is outstanding. And as someone else said, the 0-60 time is a lot better. I dont know my car's 0 to 60 time, but the 60ft time is about 1.7-1.8 seconds. Thats not much time to cover 60 feet, and i bet the bikes do it a lot quicker.
