REAL TESTS! 2010 MXA RACE TEST OF THE HUSQVARNA TC250:

  Q: FIRST AND FOREMOST, IS THE 2010 TC250 BETTER THAN THE 2009 TC250? A: We?re going to say yes, because Husqvarna did not import the 2009 TC250 to the United States. The last Husqvarna 250cc four-stroke that MXA tested was back in 2005. It was an electric-start, 237-pound, undersprung, slow bike that we said was ?a blast to ride, but not all that much fun to race.? Q: WHAT CHANGES DID HUSQVARNA MAKE TO THE TC250 FOR 2010? A: The MXA wrecking crew got a sneak peek at the 2010 Husqvarna TC250 way b…

HUSQVARNA TO BUILD A 2011 WR150 TWO-STROKE: BIGGER IS BETTER

From Husqvarna: Husqvarna has a banner crop of bikes set for the 2011 model year. Beginning with the launch of the amazing 2011 TE630 and SMS630 models earlier this spring, Husqvarna has come out swinging again with the all-new 2011 WR150.

NEXT YEAR’S BIKES TODAY! FIRST LOOK AT THE 2011 KAWASAKI KX450F!

2011 KAWASAKI KX450F INFO In the 450cc motocross game, the only thing that matters to serious racers is top-tier performance and running up front.

In this arena you can?t stand still technically, which is why Kawasaki engineers scrutinized every system and component of the race-winning 2010 model and came up with a host of tweaks that?ll have red, blue, orange and yellow wondering what hit ?e…

ASK THE MXPERTS: 2001 HONDA CR125

Dear MXA,     Can you get the rear suspension settings for a 2001 Honda CR125?  I need a good starting point.     For hardcore racing we recommended this shock set-up:     Spring rate: 4.6 kg/mm     Race sag: 100mm     High compression: 1.5 turns out (1 stock)     Low compression: 8 clicks out (9 stock)     Rebound: 20 clicks out (24 stock)     Notes: For faster riders we recommen…

FIRST LOOK! RADICAL NEW 2011 HUSQVARNA 450 REVEALED:

The wraps come off of the 2011 Husqvarna TC450. Husqvarna has begun final prototype testing of next year’s TC450 (motocross) version of the all new Husqvarna 449cc motocross motorcycle. In addition to motocross models Husqvarna will also offer TXC (cross country) and TE (street legal enduro) versions based on this platform. BMW bought Husqvarna recently and has ensconced them in a brand-new Italian factory. The 200 TC450 is second of the new breed of Huskys (the first was this year’s super lightweight T…

WE RIDE RIDE ENGINEERING’S 2010 YAMAHA YZ450F:

Just like the star quarterback in high school, the 2010 YZ450F is the BMOC this year. Everyone wants to touch it, be near it and, if possible, get a date with it. There is little doubt that this year’s Big Man On Campus caught the attention of the public with its reverse exhaust, tilted cylinder, offset cranks, downdraft EFI and cab-forward airbox. Not since the heady days of 1973 when word leaked that Honda would make a two-stroke has a bike been so eagerly anticipated (even the leaked tech info fed in…

MOTOCROSS ACTION PRODUCT TEST: PRO CIRCUIT 2010 KTM 250SXF FORK REVALVE:

WHAT IS IT? KTM’s WP forks are weird. The MXA test crew likes the 450SXF forks and hates the 250SXF forks. How can that be? We don?t know, but we do know that if we owned a 2008, 2009 or 2010 KTM 250SXF, we?d be interested in having Pro Circuit revalve the forks. WHAT’S IT COST? $675.80. CONTACT? www.procircuit.com or (951) 738-8050. WHAT STANDS OUT? Here’s a list of things that stand out with Pro Circuit’s 2010 KTM 250SXF fork revalve. (1) Stock forks.

Here’s a list of things that stand out with FMF’s Factory 4.1 CRF250 exhaust system (with MegaBomb head pipe). (1) Performance. The FMF Factory 4.1 maintained the stock CRF250’s oomph in the lower rpm range?which is just enough to help get into the midrange. The stock CRF250 powerband is at its strongest in the middle, but weak on t…

THE ULTIMATE 2010 YAMAHA YZ250F EXHAUST:

The 2010 Yamaha YZ250F is a pleasant bike, but it comes up short in the kind of power that it needs to get the job done. Designed with a low-to-mid powerband and a flat top-end, the YZ250F engine is in desperate need of help. To fix the 2010 YZ250F, the MXA wrecking crew gathered up six different exhaust systems to test. Our goal? More power! As with any test, we have caveats: We tested the exhaust systems as they were sent to us. We didn?t add any reducing cones to make the pipes quieter. We didn?t put…

REAL TEST! 2010 MXA RACE TEST OF THE HUSABERG FX450:

Not fast, not powerful, not aggressive, the FX450 asks the rider to maintain momentum, and it doesn?t get in the way if he gets the FX450 rolling. It is like a mild-mannered Clark Kent (without the Superman alter ego). Q: FIRST AND FOREMOST, IS THE 2010 FX450 BETTER THAN THE 2009 FX450? A: Yes, with a caveat. The FX450 is a new model that didn?t exist in 2009. The previous Husaberg was the enduro-based FE450. The FX450 is designed for cross-country racing, while the FE450 was largely a woods bike. Q: IS…

  MXA NEW PRODUCT: MILLENNIUM TECHNOLOGIES/CP PISTON HONDA CRF264 BIG BORE KIT: HOW TO GET MORE JUICE FROM YOUR 2010 HONDA CRF250 With earlier model Honda CRF250’s (2004-2009), it was difficult to big-bore the engine much past 256cc without endangering the cylinder liner’s structural integrity (or resorting stroking the crank). No more! Thanks to a cooperative effort between Millennium Technologies ( www.mt-llc.com ) and CP Piston ( www.cppistons.com ) it is now possible to build (at a reasonable p…

WE RIDE RYAN DUNGEY’S NATIONAL CHAMPIONSHIP SUZUKI RM-Z250:

Sometimes moments pass so fast that you don’t have time to muse on them. The 2009 season was like that for Ryan Dungey. He not only won the 250 West Supercross Championship, but the AMA 250 National Championship and the 450 class at the Motocross des Nations.  Rather than let Dungey’s triumphant year speed by in a blur, MXA decided to take the bike he rode to two AMA Championships for a spin. Here is the test of Ryan Dungey’s Championship winning RM-Z250. The greatest advantage of a factory ride ov…

Your local Yamaha dealer. WHAT’S IT DO? In stock trim, the 2010 Yamaha YZ450F is crisp, sharp and powerful from low to mid. Yamaha’s new, four-valve, reverse-cylinder engine is a creative design, but if we had our druthers, we?d want more mid-and-up power. The YZ450F’s awesome low-end power and snappy throttle response aren?t ma…

25 THINGS YOU NEED TO KNOW ABOUT THE 2010 YAMAHA YZ450F:

In its third year theYZ450F’s new rearward-slanted cylinder is still revolutionary idea that was designed for mass centralization (concentrating inertial mass toward the center of the machine). This bold design idea also swaps traditional intake and exhaust positions, putting  airbox and throttle body out front. This contributes to mass centralization,while also achieving a straight intake tract for superb combustion efficiency that delivers more power. 1. The cylinder is offset so the connecting r…

DR.D (AKA DOCTOR D) UNVEILS 2010 YAMAHA YZ450F PIPE:

STAINLESS STEEL / ALUMINUM PIPE ONLY $649.99 Dubach Racing Development had the advantage of spending countless hours track testing the 2010 YZ450F before any others. Doug Dubach, a 24-year Yamaha test rider, spent the summer working with Yamaha and developing the DR.D YZ450F SS/AL exhaust. With a revolution design, the DR.D ?Curled? exhaust improves the stock YZ power output with a more responsive bottom hit, broader mid-top power and more overrev. It is lighter, easier to repack and comes with the opti…

The 2009 KTM 250SXF pumps out 38.6 horsepower in stock trim (the 2010 model makes less horsepower because it uses the more restrictive EXC muffler). Yikes! That is powerful. For comparison, that is at least one horse more than an 2009 RM-Z250, KX250F, CRF250 or YZ250F. Even more impress…

MXA PRODUCT TEST: DR.D SINGLE-SIDED 2009 CRF250 EXHAUST: How To Make Your 2009 Honda CRF250 Look Like A 2010; Go Single, You’ll Never Go Back

WE RIDE THE SERVICE HONDA KX500AF (ACTUALLY WE HAVE CHUCK SUN RIDE IT):

By Chuck Sun From my personal motocross experience, big-bore 500cc two-strokes trigger deep emotions. First of all, a 500 championship was what all aspiring riders strove to achieve during my teenage years. And the 500 Nationals were the best place for a privateer to try to defeat the factory riders. Back in the day, when I entered the Trans-AMA International class on my 360 Husqvarna, I could earn more money by placing in the top 15 than by winning the 250 support class. A starving privateer could line…

WE RIDE CHAD REED’S MAKITA SUZUKI RM-Z450:

The 2009 season will go down as being one of the most exciting championship battles of the last decade. Chad Reed and James Stewart went toe-to-toe all the way to Las Vegas for the Supercross crown, while more riders won AMA 450 Nationals in a single season than in recent memory. Chad Reed came up a few points short in Supercross, but he outlasted all-comers in the AMA 450 National Championship. It was a great year of racing; made all the more interesting by Chad’s last-second decision to race the outdo…

WE RIDE JAMES STEWART’S L&M/SAN MANUEL YAMAHA YZ450F:

Regardless of what Chad Reed’s contingent of diehard fans think, James Stewart deserved to win the 2009 AMA Supercross title. Not only did he win seven races in a row to pass Reed for the points lead, but he came back again to win even more races and regain the lead a second time. Stewart was the Rocky Balboa of Supercross (minus the butchered Philadelphia accent). It also didn?t hurt that James won 11 races to Chad Reed’s three. Stewart showed the poise and speed of a champion. Winning every round of t…
