It’s amazing how fast motorcycles can go. I used to fix bikes in the 70s and also put in big bore kits and hot cams. Hot exhaust systems… etc. One fella came in after my modifications and complained that sometimes he could get the bike up to 160 and other times only 140. He wanted me to take it on a test run. No I said, I won’t do that. I mentioned to him that if you drive into the wind and against the wind you could possibly get that much of a difference.
A dyno’ed turbo ‘Busa can produce over 500 HP.
