The parts spinning in the engine all act like gyroscopes, so even if a 1000 and 600 weighed the same, all other things being equal, the 1000 would still be less nimble and slower to bend into corners.

Less rpms for everything inside the engine though.

A 5oz unit of mass spinning at 16500 rpm, would have the equivalent force of x spinning at 13500rpm?


I don't know the calculations, or I'd do em myself. And I know they won't be equal, I just think they're a lot closer than most people think.

Apoc's 2005 or 2006 1000rr turned in faster than my 2000 r6.

You may be on to something, but I don't know the formulas to be able to do the math.

Your example, though, suffers because there are a lot more variables involved than simply displacement. The suspension geometry of those two bikes is dramatically different, and suspension setup was probably not comparable.

Okay, displacement is governed by cylinder size which has no gyroscopic effect that I know of. I always thought that the crank and fly wheel were the main gyro culprits. Theoretically, a 600 or a 1000 "could" have the same sized crank couldn't they? Also, don't engine designers purposefully install larger than necessary fly wheels to produce a desired effect which would increase the gyroscopic effect, right? I always thought that race engine builders typically "lightened the crank" to reduce gyro effect and increase hp. I'm not sure, you seem to be the resident expert. Oh and don't discuss "gyro" effect around all these new V-Twin-aphiliacs around here.

Technically a 600 and 1000 could have a crank with the same weight and throws, but then the motor on the 1000 would have to be wider to accomodate the bigger bores needed to make up for the extra displacement.

Bigger cylinders/displacement needs bigger pistons or longer throws. Both of which weigh more on their own and need more counterweight to balance the crank.

These look like jugs to me.

that would be a rc51 or TLR right there

did we just become best friends?

yep, wanna go do karate in the garage?
