  • 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...

    US-based L.A.Sleeve is supporting a new generation of hot rodders by supplying centrifugally spun-cast ductile iron cylinder sleeve liners for fast road and drag-race use.

  • San Felipe 250 Race Report - Course Cutting, Penalties and Protests

    Once a year the sleepy beach town of San Felipe is awoken by the sounds of chase crews, pre-runner vehicles and race machines tearing around the streets and nearby desert in preparation for the season opener of the SCORE Baja series. The town may be a destination for those seeking relaxation and an escape from the hustle and bustle of the American way of life, but the race itself offers nothing of the sort. The terrain is brutal. The course features more whoops than most racers would care to hit in a lifetime and embedded rocks blending in so well with the dirt that it makes racing feel a bit like a game of Russian roulette. Maintaining focus over such unreadable terrain is of the utmost importance as the slightest mistake could end your race. Couple the mental test with the physicality of the course and the speeds required to compete and it can be argued that the San Felipe 250 is one of the toughest off road races in the world.
