I am 53 and it is amazing how most of us are right at that same age , my first bike was a Sapphire / Torquise blue 4 speed , it was licensed , had blinkers and I rode it to high school , you could get a motorcyle license at 14 back then , I could ride a wheelie in 4th gear , wide open over a mile with that bike , I'd get it up in 2nd and shift gears in the air ............... talking about speed , the fastest bike I had was when I was 18 I bought a brand new Kawaski 500 3 cylinder 2 stroke my friends Grandfather owed a hot rod bike shop here in the city and he helped me set it up , bored , ported , polished , pistons and connecting rods , opened hooker headers 3 into 1 ( sweet sound ) , carbs ,K=N air filters , coils , numerous sprockets to find the right combo , respoked Harley rear rim and larger tire , it had every trick known back then and I weighed in about 125lbs , it would only do 135mph , but it got up to 125 in seconds , it had the cafe handle bars and I would lay out on it , could beat anything on the street in 1/8th of a mile and 80% of cars and bikes in the 1/4 mile , it would pull two bike lenghts off the line on anything even the 750 Kawaski 2 strokes, 900 4 strokes and Corvettes , I finally got hurt pretty bad on it , guy didn't see me and crossed the road and I hit him broad side and flew 100 ft over his car and landed head first on the asphault on the Bell Helmet , thanks Bell .....................I remember a friend who had a Honda CB 750 and every couple of weeks after pumping hundreds into his bike he thought he was ready and going to beat me , I guess he ran out of money or things to do as it never did happen ............ one trick he never knew I was pulling was my friends Dad owned a Aviation Shop at the Airport and I was running high octane Airplane fuel
