Bio from Leslie's website.

I’m originally from Dallas Texas and have been riding motorcycles since I was 16 years old. I bought an old motorcycle from a neighbor for $200. Most of the bike was in a box. I rebuilt the carburetors, put it back together, and rode it for years mostly because everyone I knew said I would never be able to ride it.

I eventually earned an Accounting Degree but ended up working for a Yamaha shop. In a short time I owned part of the shop, opened up a second shop and sold both in 2002. I decided to go into a more ladylike profession; construction- and built spec homes in Dallas for the next 3 years. I missed the motorcycle business, sold off my properties and opened up High Five Cycles a non-franchised pre-owned motorcycle dealership in Dallas, TX in 2005.

I always wanted to set a world record at Bonneville. I bought used Hayabusa from a customer made a number of modifications and made my first Land Speed Record runs at the Bonneville Salt Flats in Utah in August of 2007. I crashed at about 110 MPH, was taken by helicopter to the hospital, with 7 broken ribs, a punctured lung, and a concussion.

I was determined to set a record so I went back to Bonneville in 2008 and set my first record at 209 MPH on a naked (unfaired) motorcycle. This record also earned me the honor of being the first woman in the Bonneville 200 MPH club on a conventional motorcycle in its 61 year history. I then set the fastest world record of any woman on a motorcycle at 232 MPH.At that same event I set the 1000 CC production class record.

In 2009, I returned to Bonneville to take the Top Speed of the Meet award (man or woman) on a motorcycle with my 240 MPH pass against a record of 227 MPH. This was the first time in history a woman has taken the award.


I currently hold, or have held, Motorcycle Land Speed records in 4 classes. My records include:
