Hilde is holding down the fort at MotoUSA's Southern Oregon HQ. With world-class dirt bike and ATV trails just minutes away, the hardest part is getting him to focus on the keyboard. Two wheels or four, it doesn't matter to our Off-Road Editor so long as it goes like hell in the dirt.

The 2012 Suzuki RM-Z450 gets new graphics and seat cover.

Suzuki recently released its latest motocross bikes and the tech sheet shows no significant updates to the 2012 RM-Z450 and 2012 RM-Z250. New graphics are slightly different with less red on the radiator shrouds, but the seat cover gets a red stripe up the middle which looks sharp and ties nicely with the Renthal crossbar pad.

The 2012 Suzuki RM-Z450 uses a fuel-injected 449cc single-cylinder engine. The DOHC, four-valve mill churns out championship-caliber four-stroke power. Ryan Dungey and Brett Metcalfe are racing the RM-Z at the front of the pack in AMA Supercross and AMA Pro Motocross and it has been adapted to win Grand National Cross Country races in the hands of Josh Strang. A five-speed transmission gives it the versatility for multiple types of tracks and racing styles.

The RM-Z450 uses an aluminum, twin-spar chassis. The fuel tank is also aluminum which is unique to Suzuki. A 47mm Showa fork handles jumps and bumps on the front end with a Showa shock on back. Both are fully adjustable.

high-revving Single contains 249cc and has impressed us in the past with its wide range of power and potent delivery. A 44mm throttle body with 12-hole fuel injector sprays fuel into the DOHC engine.

The new styling carries over to the quarter-liter machine which also features black number plates. Showa suspension is tuned for the 250 machine and agile handling is one of the RM-Z trademarks.

2012 Suzuki RM85 and RM85L
Suzuki still offers its two-stroke mini racers for youth riders. The RM85 and RM85L are unchanged for 2012 and feature an 84.7cc, liquid-cooled Single fed by a 28mm Keihin carburetor. A steel chassis and aluminum swingarm handle the abuse of a motocross track with Showa suspension components. The L model uses larger wheels (19/16-inch vs. 17/14) to help accommodate growing riders.
