  • Bell, Abbatoye and Seeds win the 10 Hours of Glen Helen

    When Ryan Abbatoye, Justin Seeds and I decided we wanted to race the 10 Hours of Glen Helen we started thinking of a way to make the experience a bit different for us. As fate would have it, Justin had a 2003 KX250 two stroke that he was just starting to assemble and it didn’t take much deliberation for us to come to the conclusion that racing a two stroke sounded like a lot of fun.

  • LAPC Honda CRF450 Piston Kit Review - MXA Team Tested

    LAPC's 2013–'14 Honda CRF450 piston kit is a performance-based piston that enhances power without diminishing reliability. Purpose: The stock 2013-'14 CRF450 produces the least horsepower in the 450 class. This isn't a dealbreaker, as the powerband is easy to ride and very tractable. But since it gives up as much as 5 horsepower to the competition, it needs more oomph...
