  • Hands down the BEST moto service anywhere

    Tom Miyao

    Hands down the BEST moto service anywhere! Nick and Mike are pro's, there is NO guess work here. just brought in a 2013 EFI ktm for service, (full race prep) and i could not be more pleased! you get what you pay for, NOTHING in moto is cheap, and if it is you'd better think twice. the old saying "you dont have a $50 head, so dont use a $50 helmet" i'm a pretty damn good wrench, but when it gets to the point where i have to break out the manual, off to pro valve i go. get it done right the first time, and then go rip!!

  • One by Nick and the other by a well known company

    Carlos Castillo

    Nick and Mike are not only fair and honest, they stand by their work. I've had two different suspension jobs done in the past. One by Nick and the other by a well known company. Nick's work is noticeably better. Taking my 3rd bike to him today.

  • The quality of work and depth of knowledge

    Michael Mahoney

    The quality of work and depth of knowledge is unparalleled for both engine work and suspension. Equally good suspension experts for trail riding old men on KTM rock crawlers in Big Bear or on the track at Glen Helen. Nick has done the testing and solicits feedback from his clients. Can't say enough…

  • Nick is the best at what he does

    Glenn Pietronico

    Nick is the best at what he does. A true professional. He's done the suspension on all of our bikes. His track support has been a god send .And he has become a great friend to our family. Thanks Nick. The Pietronico’s
