Sprocket Size Speed vs. Torque--Rookie Question...

After years of owning and working on my Enduro motorbikes, I need someone to remind me of the old rule about the 2 sprocket sizes, drive vs. driven/motor vs. wheel and how they effect speed and torque. Is it

[strike]Larger motor sprocket=more torque, less speed
Larger wheel sprocket=less speed, more torque[/strike]

**corrected:**
Larger (# of T) motor sprocket=More speed, less torque
Larger (# of T) wheel sprocket=More torque, less speed

Is that how it goes? I seem to remember it being an inverse relationship.

Rookie question, thanks.

I ordered 2x 10T motor sprockets, now I'm trying to calculate the wheel sprocket size. (Either 54, 58, or 60T)
Using 2x Tacon Bigfoot 160s

and your wheel size is???

8" MBS...but I'm asking in general terms about the relationship between the drive sprocket and the wheel (driven) sprocket, as a mechanical rule, as it applies to anything with chain drive--bikes, motorcycles, etc. I believe there is an inverse relationship between the two--I just can't remember which is which.

Actually, nevermind...sorry, I finally found a chart that explains.

From the question you asked, it would be a yes to both what you are asking. I probably believe you already get the concept of the final drive ratio....

I think it'd actually be no, for both. For the same wheel pulley, more teeth on the motor pulley would make your board faster, not slower.

Yes...corrected:

Larger (# of T) motor sprocket=More speed, less torque
Larger (# of T) wheel sprocket=More torque, less speed

I corrected the OP to avoid confusion
