The Service 500AF  Rocks the Hit TV Show Mythbusters!

It’s not every day that you pick up the phone and on the other line is Jamie Hyneman of the blockbuster show MythBusters. You can bet we were stoked when he asked about our 500AF 2-Stroke. We believe the 500AF is one of the fastest, lightest and most durable bikes on the market, and if there’s anyone willing to put it to the test, it’s the crew of MythBusters, a show dedicated to testing the enduring myths, odd ball claims, and incredulous stories that we all wonder about.



Service Honda 2 Stroke 500AF Verses Honda CRF450 4 Stroke. The Ultimate Showdown!

Four strokes are here to stay and there is no arguing the fact that they are far easier to to ride. The power delivery is much more manageable which lets the rider go longer with less fatigue. Having said that, whenever you hear someone speaking about a bike they have just ridden for the first time, invariably you hear the reference to a 2 stroke motor. Statements like “it’s really snappy, it feels just like a 2 stroke”. Here’s a news flash, it can never respond like a 2 stroke.

Motocross Action Magazine Interview: Gregg Foster - Service Honda

The men behind the logos don’t always get the publicity that their high-paid racers do. These men toil behind the scenes. These men don’t know the meaning of nine-to-five and would never be happy taking a vacation during the racing season. The motocross industry is forged by these men. They have dedicated countless hours, risked their finances, and based their lives on the premise of service to the sport of motocross.

The MXA staff decided to interview some of the mover-and-shakers of the motocross biz in an effort to share some of the wisdom, inspiration and experiences of the men behind the logos.




Selecting the perfect motor. You'll be pleased to know why!

Since we build the engines in house, from all new OEM parts, we can choose any engine style and I was never really inspired by the case reed inducted, servo powervalved, CR250 engines from 2002-2007. The 2001 Honda CR250 engine was just a great all around 250 2 stroke power plant. And one thats good for just about everyone who twists a throttle.
