I was just looking at the specs on the new Scrambler model. As a friend is putting a down payment on one.

Turns out it has a 270 degree firing order like the cruisers. Why would they do this? Is there a reason you would not want a lighter bike like this to rev like the thruxton? i dont get it... Can anyone shed light on the logic of going with the 270 firing order over the traditional 360 degree? I thought they did this to add tourque for the heavier bikes?

your thoughts?

I'd have thought that anything with off-road pretentions would have wanted torque rather than revs.

I thought the only reason for the 270deg firing order was to give the cruisers a lumpy tickover - as per V-twins.

This, boys, is a motorcycle.

hmmm.... it also makes less horsepower and torque! 54hp/51fpt compared to the thruxtox's 69hp/53fpt! What a dog, I don't get it? its the same 865cc motor right?

EBcreep,
No, it has the 865cc engine from the Speedy (270)
The Thrux and the 05 and up T-100's have the 865cc (360)
Standard Bonnies have the 790cc (360)
Americas have the 790cc (270)

:edit:

Yes, I realize that. I am just trying to understand the logic of using a version of the same motor (only the cams and crank are different) that has less peak horsepower and torque.

As for the "off road vibe" i don't think anyone in their right mind will be driving one of these in the dirt. Also i would argue that torque is not more suited for offroad. Ever ride a 2-stroke dirt bike? I'm sure all dirt bikes would all still be 2-stroke if it wasnt for the emissions concerns and they are all about the revs.

This is true.......it's about the torque. If you use the Scrambler like it should be used, it needs the power to knock you on your tush in first gear, like a dirt bike.

Mark,

Substitute Speedmaster for America and vice versa in your above post to make it correct. You risk getting a blast from the Speedy guys. :-D
