Can the 450R motor be stroked?

[razer]

I read the Yamaha motor doesn't have to the room. How about the Honda? Can it be stroked, say 4 mm?

Anybody know?

The TRX is already a stroked version of the CRF motor, but with a smaller piston. More stroke will give you more torque and midrange power, which I feel the honda has more than enough of! But theorotically speaking, i don't see why the honda couldn't be stroked, chances are, it would need some type of spacer or different piston, to compensate for the 4 mill stroke though.
