American Honda has released details on the 2012 model CRF motocross range, with a host of modifications implemented across the board.

In 2012, Honda has put forward a host of upgrades for the ever popular CRF450R, including fitting a stiffer fork outer, stiffer fork springs, and revised suspension settings front and rear.

Also at the rear there’s a new shock linkage for improved tracking, more precise handling and added rider confidence over rough terrain according to Honda.

New, longer and wider footpegs offer more support with a larger platform have also been fitted for the year ahead.

The 2012 model Honda CRF450R is expected to be released in the second half of this year.

Also revised is the 2012 Honda CRF250R, which has received a new cylinder head, camshaft and 46mm throttle body to produce a broadened powerband featuring more low-end and midrange torque according to Honda’s press materials in the U.S.

In addition, a new suspension linkage along with updated suspension settings front and rear also mark fresh changes.

Also like the 450, longer and wider footpegs have been fitted, and it’s also expected for release in the second half of 2011.

The revisions haven’t been limited to the 450 and 250 though, with the 2012 model CRF150R and CRF150RB benefiting from a new cylinder head, piston, camshaft and carburetor. Like its big brothers, there are also updated suspension settings front and rear.

Confirmation on these models is yet to be released by Honda Australia.
