DON’T MISS IT! THE NEW MXA IS ON THE NEWSTANDS NOW: WE TEST THE FASTEST 250 TWO-STROKE EVER, WE RIDE RICKY DIETRICH’S YZ450F, WE BUILD A YZ310 & WE TALK TO BROC HEPLER


MXA’s Dennis Stapleton takes a break from his globe-trotting to throw a leg over Ricky Dietrich’s Valli Yamaha YZ450F for the September cover. It was one weird machine.


In this issue the MXA test crew evaluated everything from biogredable tear-offs (didn’t like them) to Super B KTM batteries (didn’t like the price tag) to “MX vs ATV: Alive” (thought it was the worst version ever) to a Pro Circuit KTM 250SXF exhaust system (this bike needs help).


We thought that we’d never ride a bike as strangely set-up a Ricky Carmichael’s bikes (and we tested a lot of Ricky’s bikes throughout his career). We were wrong. Ricky Dietrich’s set-up rivals RC’s.


Broc Hepler tells an important tale of the effects of post-concussion syndrome…and gives advice to young racers.


Jody brings the tech revolution that motocross seems to be going through into sharper focus?you’ll never look at the “latest thing” in the same way again.


Whether you are for ’em or agin ’em, you need to read this 2012 KTM 250SX two-stroke test to truly appreciate what is possible without cams, valves or $1500 repair bills.


What could you do with an extra 60cc? The MXA gang wanted to find out. Thumper Racing’s YZ310 test tells you just how big you can go.


MXA presents a plan to solve the sound testing riddle?which is so complicated that the AMA is almost afraid to test bikes anymore. Our plan is simple, fast and foolproof (which is required for the AMA to use it).


Do you remember Kalevi? No, not Pekka, but his uncle Kalevi. The Montesa VR (Vehkonnen Replica) is a beautiful bike.


The 2012 Yamaha’s have been forgotten in the shuffle. They hit the showrooms on September 14, but you can see them up-close and personal in the September issue of MXA.
