What engine do you guys think it will have?

I heard its DRZ400 based..

Might just be a bored/stroked drz motor, with high performance cams/porting/compression

 

[midwestrider]

could it be all new?

I doubt it would be DRZ based when they already have a DRZ based quad (z400) Honda did the same thing. Their 400ex is basically a detuned XR 400 engine. The new 450's on the other hand, are all new and I'm expecting this one to be the same.

I speculate that it will be based off the RM-Z450 engine, the same way the YFZ engine is based off the YZF450 and the TRX450 is based off the CRF450 engine.

No need to reinvent the wheel when there's a perfectly good engine already being used in their motocross dirtbike.

either that or its a all new one b/c it took forever

 

[Bigless36]

I think it will be an all new engine

 

[Bigless36]

From the pictures it looks like a totally new engine

It is most deffinatly DRZ based, but the reason it too so long is because of the tranny, they took a lot of time tring to get it just right. COnstant mesh 5 speed. Me gusta :wink:
