 Not yet, but it could be a reality for you very soon!
Sparks Racing has definite plans to develop the CRF450R
motor for ATV racing. There will likely be a limited
supply of motor available for sale. Also, Curtis has
plans to build the very first Sparks chassis for the
CRF450R motor to aid in the development of the motor for
ATV racing. We will post more details as they become
available, but if you are interested, please contact us
right away. In case you have been under a pile of rocks
and haven't heard of the new CRF450R, Honda has decided
to take over the top four-stroke MX spot from the
YZ426F. Currently, Ryan Hughes is competing in the
outdoor nationals on it and has managed to gather up a
few holeshots. Heath Voss raced at the final round of
the Supercross series in Las Vegas and ripped some of
the fattest holeshot's seen at a Supercross. The motor
definitely has authority and it's a Honda. Here are a
few pics and some specs on the motor and the bike.

Displacement comes in at 449cc (96mm x 62.1mm). It has a
SOHC, four valves, 11.5:1 piston. The carb will be a
Keihin 40mm FCR (wonder why we recommend the FCR for the
400X?). Honda is claiming 55bhp at 9000 rpm and 36 lb/ft
at 7000 rpm. The engine weighs in at 65.4 lbs. Honda
chose Titanium intake valves and a system to make cold
and hot starting superbly easy. Basically it is a Honda
and it will be completely awesome.
