WE RIDE PRO CIRCUIT’S 60-HORSEPOWER HONDA CRF450

The 2013 Honda CRF450 is the most discussed bike of the year, thanks in part to a new model change and because, to put it bluntly, it’s red. Honda has long held the attention of the buying public. Honda is known for their dominance during the 1980s, with racing greats such as David Bailey, Johnny O?Mara, Donnie Hansen and Ricky Johnson, continuing through the ?90s with Jeff Stanton and Jeremy McGrath, and onward to a new millennium with Ricky Carmichael and Trey Canard. A reputation for quality products…

The March 2013 issue of MXA is in the mail and on the shelves right now.

Not only did we weigh them, sound test them, dyno them, race them and do back-to-back tests with a Novic…

TEN THINGS YOU NEED TO KNOW ABOUT YOUR CLUTCH

(1) Although the clutch in your bike may seem like a complicated mechanical device, nothing could be further from the truth. A motorcycle clutch is a ?deadman switch.? When it is pulled in, the engine is disconnected from the drivetrain. When it is released, the engine and the drivetrain are hooked up. (2) The working mechanism on a motocross bike’s ?deadman switch? is a spring-loaded coupling that has enough spring pressure to keep the  side geared to the crankshaft and the side geared to the tran…

MXA’S FIRST RIDE ON THE PRODUCTION 2013 HONDA CRF450: WHAT WE KNOW & WHAT WE ARE WILLING TO TELL

2013 Honda CRF450. We know that everyone wants to know everything there is no know about the 2013 Honda CRF450…and they want to know it now, but MXA is ready to pontificate this early in the process. At the moment we are testing different combinations of springs, gearing, air pressure, setup and details. We have yet to dyno it, weigh it or sound test it…although we have raced it.

AMA RULE OF THE WEEK: WHERE ART THOU, TRACTION CONTROL?

The following AMA rule is so poorly written that it doesn’t actually ban much of anything. Read it carefully. Part 1.14 a says that “electronic devices specifically designed for traction control are prohibited.” Does that mean that an electronic device that monitors fuel and the ignition and also has traction control would be legal? After all, it isn’t specifically designed for traction control? The second half of part a says that “This includes sensors that can determine front wheel speed, and any elec…

Belleville washers are a type of disc-shaped cup with an extremely high tensile strength. Originally developed in the mid-19th century by Julian Belleville, Belleville springs are used in a variety of environmen…
