Why does shipping cost so much?
It is a huge book! The book itself weighs 2.2lbs plus another 0.3lbs for the box and packing materials and we are nearly at 3lbs. To be completely honest, this is the most affordable shipping available via USPS for international orders if you want your book to arrive in a timely manner.

How will my book arrive?
Your book will arrive shrink wrapped in a 12" x 9" x 4 3/4" box.

MEET THE AUTHOR
Paul Olesen is Wisconsin native who has always had motorcycles on his mind. From tearing apart his first bike at the age of 18, his curiosity around engine design has guided his entire career. 

During his years in the UK attending the University of Wales, Paul not only received his degree in motorcycle engineering, but he also designed and built his own racing motorcycle from the ground up. He spent his summers stateside, where he interned as a design engineer for S&S Cycle. While there, he built the fairing for their Bonneville racing bike and worked on the 2012 racing team.

It was through this education and exploration that Paul honed his engineering knowledge, which launched him head first after graduation into a powertrain position at Erik Buell Racing. After spending just over a year there, Paul realized his time was better spent educating the everyday rider through DIY Moto Fix. In doing so, he is bent on keeping the world of motor sports alive and well.
​
Currently, Paul holds a position as the Principal Development Engineer at DeltaHawk Engines, where he is designing and developing a two stroke diesel engine for aviation. ​
