I eventually wrote a book about motorcycle drag racing, called "Nitrous Wars," the black book of nitrous oxide racing. My son earned his motorcycle license at 16 years old, and purchased a Ninja 250, followed by a new left-over SV650S, and now a 1999 ZRX1100. We shared many miles together on all of his bikes. I had to recently sell my '02 ZZR1200 that I put 50,000 carefree miles on, due to neurological issues. I miss, more than anything, riding with my son. For me, that was my Nirvana. Did I mention, we love Kawasakis?
