MXA’S 2006 TM125MX DIRT BIKE TEST

TM, the Italian bike manufacturer, has been around for many years, and their claim to fame (as far as a marketing strategy goes) is that they are the only manufacturer offering a full-blown factory bike to the public

RESTORE THAT OLD DOG! WE BRING A 2006 YZ250F BACK FROM THE DUMPSTER

Home sweet home. The MXA wrecking crew dug it out of the trash heap, lavished it with beaucoup bucks and ended up with a new 2006 YZ250F. This is a bike test unlike any other test that we have done in recent memory. The MXA gang is not test riding an uber-expensive factory machine, a big-bore fire breather or even a new 2012 bike. Nope. We have focused our attention on an old roach of a bike on the brink of death?a bike that was doomed to spend eternity collecting dust. And so goes the typical story of …

WE BUILD AN L.A. SLEEVE YAMAHA YZ270:

If you own a 2006 to 2010 Yamaha YZ250, consider yourself lucky. You have one of the best motocross bikes ever made. It weighs less than a comparable four-stroke, costs less to repair and produces more horsepower per cc. And most importantly, it comes stock with Kayaba SSS suspension. It is a sweet motocross machine. However, there is a but. If you are racing your YZ250 against 250cc four-strokes, you have a superior motocross machine; but if you race the 450 class on your YZ250, you are giving up a bun…

THE BEST USED BIKES! WHICH 450’s TO KEEP FOR ANOTHER SEASON? Which Used Bikes To Save And Which Ones To Jettison; We Name Names

CAN MY OLD 450 MAKE IT ANOTHER SEASON OR TWO? THE MONEY YOU SAVE CAN FINANCE YOUR RACING CAREER    Let’s take it for granted that your trusty, but rusty, old bike isn’t leaking fluid out of the shock, making clunking noises at low rpm, suffering from terminal rust behind the ignition cover, cracking down the head tube like old concrete or oozing tranny oil that looks more like chocolate milk than 30 weight. If your bike is sound and air worthy, your next questions should be:  …

WE RIDE CHAD REED’S WORKS YAMAHA YZ450F

GETTING A CHANCE TO TEST RIDE A WORKS BIKE, IN THE MIDDLE OF THE AMA RACING SEASON, WOULD BE LIKE  FERRARI LETTING YOU TAKE MICHAEL SCHUMACHER’S FERRARI DOWN TO THE STORE FOR A QUART OF MILK ON THE EVE OF THE GRAND PRIX OF MONACO. Getting a chance to test ride a works bike, in the middle of the AMA racing season, would be like Ferrari letting you take Michael Schumacher’s Ferrari down to the store for a quart of milk on the eve of the Grand Prix of Monaco. Factory teams are protective of their mach…

WE RIDE MAXPOWER/RPM’S BIG-BORE KX315

    WITH TODAY’S METALLURGICAL CONFIGURATIONS, IT IS POSSIBLE TO MAKE AN ENGINE PRODUCE MORE POWER, ACCELERATION, SPEED AND SENSATIONS THAN THE HUMAN MIND CAN PROCESS OR HUMAN BODY MANAGE.             Formula 1 race car designers, from as far back as Colin Chapman, have understood that there is a delicate balance between weight and power. In truth, the never-ending pursuit of power has pretty much ended, and if it weren’t for computer mana…

WE RIDE SEAN COLLIER’S STAR RACING YAMAHA YZ250F

  IT’S NO SECRET THAT EVERY RACE TEAM LIKES TO THINK OF THEMSELVES AS THE CENTER OF THE UNIVERSE.  IT’S HUMAN NATURE TO THINK THAT EVERY MOTOCROSS FAN KNOWS WHO THEY ARE. As he’s a neighbor of Motocross Action’s managing editor Tim Olson, we’d love to say Sean Collier volunteered to let the MXA wrecking crew take his 2006 Star Racing YZ250F and thrash on it. Truth is, Sean was busy at the Yamaha Supercross test track in Corona, California, and wouldn’t be able to help us in our quest to try ou…

WE RIDE PRO-CIRCUIT’S RC REPLICA RM-Z450

    THANKS TO THE AMA PRODUCTION RULE, AS FEEBLY ENFORCED AS IT IS, MOST FACTORY RACE BIKES ARE FINELY TUNED VERSIONS OF SHOWROOM STOCKERS. What’s the difference between a works bike and a stock bike? Cubic dollars. Big bucks. Massive infusions of loot. Moolah. Filthy lucre. Greenbacks. What does all that cash buy? You probably think that it buys exotic one-off parts. Not true. Most of the trick parts on a modern works bike are obtainable on the open market. Thanks to the AMA production r…

WE RIDE PIONEER’S BIG-BORE SUZUKI RM-Z475

  NAMED AFTER THE EMBARRASSINGLY SHALLOW MTV SHOW, WHERE CELEBRITIES SHOW OFF THEIR  HOMES, SHOES, CARS AND SPAS, THE “CRIBS EFFECT” HAS SPREAD THROUGHOUT EVERY SOCIAL STRATA OF AMERICAN SOCIETY. Pssst! Wanna know a secret? Four-stroke buyers are bucks-up. They are better off financially than any group of motocross racers in the 35-year history of the sport. Suddenly, it appears as though everybody in America is rich?ostentatiously so. Modern racers are more than willing to spend beaucoup mone…

WE RIDE MB1/TOKYO MODS HONDA CRF450

  Einstein’s theory: Tokyo Mods’ engine formula is simple. Make the most power and make it right now. AS PART OF THE MXA FAITHFUL, YOU NO DOUBT REMEMBER THAT WE TESTED BOTH A STAND-ALONE MB1/TOKYO MODS HONDA CRF250 AND A CRF450 IN OUR INFAMOUS BLIND-TASTE-TEST PEPSI CHALLENGE. This isn’t the MXA wrecking crew’s first rodeo with the MB1 and Tokyo Mods boys. As part of the MXA faithful, you no doubt remember that we tested both a stand-alone MB1/Tokyo Mods Honda CRF250 and a CRF450 in our infamous bl…

WE RIDE DR. D’S HONDA CRF450

Bullet train: MXA’s melding of Suzuki, Yamaha and Kawasaki specialists produced a Honda CRF450 that is untouchable. You better be ready before you pull the trigger.   HISTORICALLY, FACTORY RIDERS MAKE BAD TEST RIDERS FOR ANYONE BUT THEMSELVES AND, UNFORTUNATELY FOR THE SALES DEPARTMENT, THEY DON’T PAY FOR THEIR BIKES. Test riders with the knowledge and gumption to tell the factory test engineers the truth are hard to come by. Don’t think that you can find them on the race teams?no way. Fast motorcy…

2006 YAMAHA YZ250F TEST

  As much as a giant, monolithic, multinational corporation can be, Yamaha is a rebel. As a rule of thumb, Yamaha always takes the road less traveled. Need proof? How about the first single-shock motocross bike (Monoshock)? First Brake Activated Suspension System (BASS)? First power valve-equipped exhaust port (YPVS)? First aluminum-framed works bike (YZM500)? Or, the granddaddy of all firsts, the first modern-era four-stroke motocross bikes?   While the rest of the manufacturers were busy per…

MXA PRODUCT TEST: YOSHIMURA RS3 CRF250 EXHAUST

  WHAT IS IT? Yoshimura’s take on the Honda twin-piper.   WHAT’S IT COST? $1175.00 (carbon fiber), $1075.00 (titanium), $750.00 (stainless steel)(909) 628-4722. http://www.yoshimura-rd.com   WHAT’S IT DO? Honda’s new twin-pipe exhaust has been a mixed bag for the consumer. Everyone thinks the design looks really cool, but very few feel, hear or see any actual difference in performance. Most devastating for consumer confidence is that buyers are scared to death about what it will cost to r…

MXA’S 2006 KTM 450SXF TEST

Have you heard of Maico? Bultaco? BSA? Ossa? Montesa? CZ? Rickman? Sure you have, but they’re only discussed when the subject of defunct European motorcycle brands is brought up. KTM was a contemporary of those dear departed brands, yet it is still standing, still in business, and still fighting the good fight. The Japanese industrial juggernaut of the late ?70s wiped most European motorcycle companies off the face of the earth, but KTM withstood the onslaught. How did they survive when all those around…

MXA’S 2006 KTM 250SX DIRT BIKE TEST

KTM was the smallest of the Big Five. It didn’t have the massive output in scooters, golf carts, power equipment, automobile engines, oil tankers, airplanes and motocross bikes of Honda, Yamaha, Suzuki and Kawasaki. But small isn’t necessarily a bad thing!

2006 HONDA CRF250 TEST

Buzz is a weird thing. Public attention is drawn to Ben Affleck when it comes to his personal life, but nobody goes to see his movies. New motorcycles aren’t all that different when it comes to buzz. Common sense would tell you that the all-new aluminum-framed KX250F and YZ250F would be the subject of all the pit chatter. Not so. The twin pipes on the CRF250 double-trump everything else on the public’s radar. How do we know? That’s simple. Every time we take our 2006 KX250F and 2006 CRF250 to a local tr…
