Now that's good thinking Xlerate. Lighter has got to better (reducing weight equates to more power, or something like that). And the 'balancer shaft' - what a beautiful dream!

I hope so, xlerate, I hope so.

Thanks for the reply.

Cheers,

That's the first time I've heard someone say 'one GOOD engine'. Interesting idea. 'Cos modern manufacturing likes 'modularity', that would make good sense, especially since there are significant parts not shared between the 883 & 1200.

Good point Akdawg!

Evening Steve - a good point, shared by Xlerate. I found out recently that the Sportster engine weighs MORE than a Twin Cam. Fancy. (No, I can't remember where!)

We can only hope AZ. (But PLEASE play nice - it was only a joke.)

That's only because it's got a transmission & primary built-in. It's not heavier than a Twin Cam + transmission + primary...

Morning Roscoe - ofcourse, I didn't think of that. One's unit construction and one isn't. D'uh. But I do remember where I got the (approximate) respective weights from: it was Donny Petersen's awesome 'Unauthorised Technical Guides'. (I am soooooo hoping he'll do an Evo Sportster edition - or, preferably, two: rigid and rubber.)

Cheers,

Since the Street models, 500cc and 750cc seem to have gone away at least in the US, Harley a while back indicated 4 engine sizes.

500, 975 and 1250 with likely another one at 750cc.
The 500 and 750 would be replacements for the Street models and the 975/1250 for the Evolution replacement.

Afternoon Shanneba - it's been a (long) while as I've been, you know, busy. Anyway, this is a thorny issue for me (see my YouTube vid) as I don't think the RevMax is an Evo replacement. Others... many others... disagree though...

Still, next video will pursue this further (hopefully, on the 12th).

Cheers,

Chris
