In the same day, Peter set a new 125GP track record of 59.14s.
After the first two rounds, Peter was leading the USGPRU (United States Grand Prix Racers Union) West Coast 125GP and 250GP class championships.  Mid-season Peter crashed into a tire wall  at Portland International Raceway (PIR) on May 31, 2009 due to several mechanical failures. He suffered several broken bones (tibia and fibula just above the boot line; a broken femur; and a broken humerus just above the elbow) requiring several surgeries. The arm also suffered a severed radial nerve. The accident effectively ended Lenz’s 2009 season and his run at the USGPRU 125GP and 250GP motorcycle road racing national championships. Full recovery is expected with plans to return to racing in 2010.
Peter began riding in the dirt on a Yamaha PW50 when he was 5 and quickly started racing it. He soon moved up to a KTM Pro Senior 50. At age 7 he transitioned to pocketbikes on pavement which he rode for the next 2 years, finishing with an undefeated season.  Peter then advanced to racing minis for 3 years on a variety of bikes including: Honda NSR50, KTM 65SX roadracer, Metrakit MiniGP 50 and 80 and Honda RSF150R.
2005 was Peter’s first season riding pocketbikes (see Pocketbike racing) as well as being a member of the BMS Factory Racing, USA Team. He finished the season taking 4th Overall in the Junior division of OMRRA (Oregon Motorcycle Road Racing Association).
In 2006 Peter rode a full season with OMRRA and joined Portland, Oregon based FNB Racing.
In March he traveled to France, to visit the BMS factory, and Spain where he placed 4th & 6th in an internationally attended pocketbike race.
At the Canadian Mini Nationals sanctioned by the CMA in August at Quesnel, BC, Peter went home as the 2006 CMA Canadian National Open Pocketbike Champion & the Canadian Junior National Pocketbike Champion.
Peter also raced his first year in MiniGP on his NSR50 finishing as the NMRRA Mini50 GP Class Champion. Peter completed the season as the OMRRA Junior Overall Pocketbike Champion and announced his retirement from pocketbikes.
In 2007 Peter rode undefeated in the 50cc classes for the Metrakit Canada Factory team  on a Metrakit 50 with ambitions of winning several Canadian National titles. Unfortunately, a startline crash  resulted in a broken arm taking Peter out of the series and along with it, his ride with Metrakit. He finished the year aboard his Honda NSR50 and his KTM 65SX motard racer taking a total of 4 national wins, 34 regional wins, and an additional 14 podiums for the season.
In 2008 Peter focused on full-size GP chassis bikes.

He also ran the Can-Am Mini Motorcycle Roadracing Championship Series  in which he won four National Champion titles. He also won the CMA Canadian National Formula Thunder Championship
